One of our favorite Shark robot vacuums is 58 percent off right now for Black Friday

Posted on by

Our pick for the best robot vacuum (or at least one of its many variants) is on sale. Amazon's Black Friday deals include the Shark AI Ultra robot vacuum. This model has a list price of $599, but you can snag one for $250. That's 58 percent off — and a record low.

One of this model's standout features is its bagless design. Like many robovacs, it has an auto-empty station. But here, you can remove part of the base, dump its contents in the garbage, and lock it back in place. The base holds up to 60 days of dirt and debris, and you'll never need to order bag refills.

The Shark AI Ultra has strong suction and decent obstacle avoidance (via LiDAR). The robovac cleans in a matrix grid. It auto-maps your home and supports Google Assistant and Alexa for voice control.

The vacuum has a runtime of about 120 minutes. (If it needs to stop and charge, it will auto-resume afterward.) Also note that this is a vacuum-only model: no mopping here.

But Shark has other Black Friday deals if you're interested in a robovac that also mops, or even a cordless stick vacuum instead. The Shark Stratos 2-in-1 robot vacuum and mop is 60 percent off and down to $400 right now, while the Power Detect Pet Plus cordless vacuum with self-emptying base is down to $380.

Monocoque Drone with Hubless Rotors is designed to withstand any extreme flying conditions

Posted on by

Ask any experienced drone pilot about their worst crash, and you’ll likely hear a story that ends with a collection of fragmented parts. The conventional quadcopter design, while effective at flying, is notoriously poor at surviving the unexpected kinetic events that come with operating in the real world. Whether it’s a sudden gust of wind, a GPS error near a structure, or a simple pilot miscalculation, the result is often the same: a compromised frame and a costly repair.

With the Mono Mothra, we see a design that fundamentally rethinks this vulnerability. The concept’s strength lies in its two core principles: a load-bearing monocoque shell and protected, ducted rotors. Instead of discrete arms that can snap and motors that can be damaged, the entire structure is designed to absorb and distribute impact forces. It’s a “what if” exploration into a different kind of aerial platform, one where resilience isn’t an afterthought but the very cornerstone of its design philosophy.

Designers: Rify Studio® & Martunis

Unlike the familiar bolted-together cross-frame of most drones, the Mono Mothra is conceived as a single, continuous unibody. This monocoque approach, common in automotive and aerospace applications, means the outer skin is the primary structure. There are no joints between the central body and the rotor housings to act as fracture points. An impact on the outer ring doesn’t concentrate stress on a single screw or plastic weld; the force is spread across the entire continuous surface. This not only creates a far more durable machine but also allows for a cleaner, more holistic form where every curve is both aesthetic and structural.

This philosophy of integration extends directly to the propulsion system. The outer ring of the monocoque doubles as a set of four substantial propeller guards, completely enclosing the rotors. This ducting provides an obvious and immediate layer of protection against side impacts with walls, branches, or the ground. The renders hint at a clever mechanical solution for the hubless look, with a gear-driven system hidden beneath the rotors. While a gear-driven system introduces complexity compared to a direct-drive motor, it allows the design to maintain its clean top profile and fully protected rotors, reinforcing the drone’s identity as a ruggedized tool.

The camera module itself rejects the fragile, exposed gimbal common on consumer and prosumer drones. Instead, the lens is bunkered within a solid, purpose-built housing that appears to be just as robust as the main body. Whether the ribbed side panels are functional heat sinks for a high-performance sensor or purely an aesthetic choice, they communicate a sense of durability. The entire unit is mounted securely to the forward section of the frame, suggesting it is an integral part of the drone’s hardened structure rather than a delicate payload that has been simply attached.

What a concept like Mono Mothra truly demonstrates is the necessary evolution for drones to mature beyond their hobbyist origins. The industry’s current focus on modularity has created a landscape of capable but delicate machines. This design, by contrast, argues for a future built on structural integrity, where a drone’s ability to withstand the environment is as important as its ability to fly. It’s a shift from disposable components to a resilient, unified whole – a critical step if these devices are to become the indispensable, all-weather tools promised to professionals.

The best robot vacuums on a budget for 2025

Posted on by

Robot vacuums have become ubiquitous over the past few years, in the sense that there are more options to choose from now than ever before. In their early years, you'd have to dish out $500 or more to get a decent robot vacuum, but that's not the case anymore. Sure, you could pick up a $1,000 cleaning behemoth with mopping features, but it would be incorrect to assume that you need to spend that much money to get a good machine.

Now, you can get an autonomous dirt-sucker to do one of your least favorite chores (and do it pretty well) by spending $300, or less in some instances. But you get what you pay for in this space; don’t expect affordable robot vacuum cleaners to have all of the bells and whistles that premium machines do, like self-emptying capabilities or advanced dirt detection. Engadget has tested dozens of robot vacuums at various price points over the years and we've narrowed down the best budget robot vacuums you can get right now.

Since I've tested dozens of robot vacuums, I'm often asked if these gadgets are "worth it" and I'd say the answer is yes. The biggest thing they offer is convenience: just turn on a robot vacuum and walk away. The machine will take care of the rest. If vacuuming is one of your least favorite chores, or you just want to spend less time keeping your home tidy, semi-autonomous robotic vacuum is a great investment. Many models, albeit more expensive ones, even come with features like a self-empty station to further reduce maintenance.

There are plenty of other good things about them, but before we dive in let’s consider the biggest trade-offs: less power, less capacity and less flexibility. Those first two go hand in hand; robot vacuum cleaners are much smaller than upright vacuums, which leads to less powerful suction. They also hold less dirt because their built-in bins are a fraction of the size of a standard vacuum canister or bag. Fortunately, some models include features like an auto-empty station, which helps with dirt capacity, especially in homes with pet hair.

When it comes to flexibility, robot vacuums do things differently than standard ones. You can control some with your smartphone, set cleaning schedules and more, but robo-vacs are primarily tasked with cleaning floors. On the flip side, their upright counterparts can come with various attachments that let you clean couches, stairs, light fixtures and other hard-to-reach places.

When looking for the best cheap robot vacuum, one of the first things you should consider is the types of floors you have in your home. Do you have mostly carpet, tile, laminate, hardwood? Carpets demand vacuums with strong suction power that can pick up debris pushed down into nooks and crannies. Unfortunately, there isn’t a universal metric by which suction is measured. Some companies provide Pascal (Pa) levels and generally the higher the Pa, the stronger. But other companies don’t rely on Pa levels and simply say their bots have X-times more suction power than other robot vacuums.

So how can you ensure you’re getting the best cheap robot vacuum to clean your floor type? Read the product description. Look for details about its ability to clean hard floors and carpets, and see if it has a “max” mode you can use to increase suction. If you are given a Pa measurement, look for around 2000Pa if you have mostly carpeted floors. Pay attention to the brush roll mechanism as well, especially if you're dealing with dog hair or other stubborn debris that can cause tangles. Many budget models use bristle brushes, while others offer tangle-free designs to minimize maintenance.

You may find some budget robot vacuums also offer vacuum/mop combo capabilities. These bots feature a water tank, which means they can offer mopping functionality, enhancing debris pickup, and resulting in shiny floors. However, these are less common when you’re shopping in the lower price range.

Size is also important for two reasons: clearance and dirt storage. Check the specs for the robot’s height to see if it can get underneath the furniture you have in your home. Most robo-vacs won’t be able to clean under a couch (unless it’s a very tall, very strange couch), but some can get under entryway tables, nightstands and the like. As for dirt storage, look out for the milliliter capacity of the robot’s dustbin — the bigger the capacity, the more dirt the vacuum cleaner can collect before you have to empty it.

You should also double check the Wi-Fi capabilities of the robo-vac you’re eyeing. While you may think that’s a given on all smart home devices, it’s not. Some of the most affordable models don’t have the option to connect to your home Wi-Fi network. If you choose a robot vac like this, you won’t be able to direct it with a smartphone app or with voice controls. Another feature that’s typically reserved for Wi-Fi-connected robots is scheduling because most of them use a mobile app to set cleaning schedules.

But Wi-Fi-incapable vacuums usually come with remote controls that have all the basic functions that companion mobile apps do, including start, stop and return to dock. And if you’re concerned about the possibility of hacking, a robot vac with no access to your Wi-Fi network is the best option.

Obstacle detection and cliff sensors are other key features to look out for. The former helps the robot vacuum navigate around furniture while it cleans, rather than mindlessly pushing its way into it. Many also offer no-go zones, letting you block off areas you don’t want the robot to enter. Meanwhile, cliff sensors prevent robot vacuums from tumbling down the stairs, making them the best vacuum for multi-level homes.

When we consider which robot vacuums to test, we look at each machine’s specs and feature list, as well as online reviews to get a general idea of its capabilities. With each robot vacuum we review, we set it up as per the instructions and use it for as long as possible — at minimum, we’ll use each for one week, running cleaning cycles daily. We make sure to try out any physical buttons the machine has on it, and any app-power features like scheduling, robot mapping and more.

Since we test robot vacuums in our own homes, there are obstacles already in the machine’s way like tables, chairs and other furniture — this helps us understand how capable the machine is at avoiding obstacles, and we’ll intentionally throw smaller items in their way like shoes, pet toys and more. With robot vacuums that include self-emptying bases, we assess how loud the machine is while emptying contents into the base and roughly how long it takes for us to fill up the bag (or bagless) base with debris.

First and foremost, always empty your robot vacuum’s dustbin after every cleaning job, or use a self-empty station if the model supports it. Simply detach and empty the dustbin as soon as the robot is done cleaning, and then reattach it so it's ready to go for the next time. It’s also a good idea to take a dry cloth to the inside of the dustbin every once in a while to remove any small dust and dirt particles clinging to its insides.

In addition, you’ll want to regularly examine the machine’s brushes to see if any human or pet hair has wrapped around them, or if any large debris is preventing them from working properly. Some brushes are better than others at not succumbing to tangled hair, but it’s a good idea to check your robot’s brushes regardless — both their main brush and any smaller, side brushes or corner brushes they have. These parts are often easy to pop off of the machine (because they do require replacements eventually) so we recommend removing each brush entirely, getting rid of any tangles or other debris attached to them and reinstalling them afterwards. If you have a robot vacuum with mopping capabilities, you’ll need to wash the bots’ mop pads too, to avoid any unpleasant smells or tracking mess around your home. Similarly, if your robot vacuum has a water tank, it’s worth washing this out regularly to keep it clean.

Robot vacuums also have filters that need replacing every couple of months. Check your machine’s user manual or the manufacturer’s website to see how long they recommend going in between filter replacements. Most of the time, these filters cannot be washed, so you will need to buy new ones either directly from the manufacturer or from other retailers like Amazon or Walmart.

Yes, budget robot vacuums can be good for pet hair. Just keep in mind they generally tend to have lower suction power and smaller dustbins than more expensive (and larger) robot vacuums. If pet hair is your biggest concern, we recommend getting as expensive of a robot vacuum as your budget allows, or consider investing in a cordless vacuum since those tend to be more powerful overall.

Budget robot vacuums typically last 40-60 minutes per charge, and the best ones will automatically return to their charging dock when they need more power.

Yes, budget robot vacuums work on both carpets and hardwood floors.

Home mapping features are typically exclusive to more expensive robot vacuums. Check the product description of any robot vacuum you're thinking of buying and look for "smart mapping" or "smart home mapping" in the feature list if you want a device that supports it.

This Interstellar-Inspired Robot Actually Walks and Rolls

Posted on by

Remember that sarcastic rectangular robot from Interstellar that somehow managed to walk, roll, and save humanity while delivering deadpan one-liners? Yeah, turns out someone actually built a working version of TARS, and it’s just as mesmerizing as you’d hope.

Meet TARS3D, the brainchild of roboticist Aditya Sripada and his longtime collaborator Abhishek Warrier. What started as what Sripada calls “a desire to reconnect with the simple joy of building robots” has turned into something that looks like a collapsing sculpture decided to get up and move across your living room floor. It’s weird, it’s wonderful, and it’s earning serious academic recognition.

Designers: Aditya Sripada and Abhishek Warrier

If you’ve seen Christopher Nolan’s Interstellar, you know TARS. That blocky, impossibly versatile assistant robot that accompanied astronauts across alien landscapes, morphing from a walking tower of metal rectangles into a rolling wheel when speed was needed. The movie version was actually a human-sized puppet with operators digitally erased from scenes, and its wheel form was attached to a motorized dolly. Movie magic, not actual robotics. But Sripada, who holds a master’s degree from Carnegie Mellon University’s Robotics Institute and works as a senior robotics engineer at Nimble.ai, wasn’t satisfied with movie illusions. He wanted the real deal.

TARS3D features four independently articulated telescopic pillars that transform into an X-shape faster than you can say “Cooper, this is no time for caution.” Pillars one and three rotate forward while pillars two and four swing back, and curved pads extend from the tops and bottoms of each pillar to serve as feet. The result? An eight-spoke double rimless wheel that actually rolls. According to Sripada, this is the only recreation of TARS that can genuinely both walk and roll.

What makes this even cooler is the tech behind the transformation. Sripada and Warrier wrote an entire research paper titled “Walking, Rolling, and Beyond: First-Principles and RL Locomotion on a TARS-Inspired Robot,” which explores reinforcement learning-based control for the robot’s gait. They’re combining first-principles physics with modern learning techniques, a hybrid approach that opens new possibilities for adaptable locomotion in robotics. The paper was named a finalist for the Mike Stilman Award at the 24th IEEE RAS Humanoids Conference in Seoul, which is essentially the Olympics of humanoid robotics research. Pretty impressive for what started as a curiosity project.

Here’s the thing that makes TARS3D particularly fascinating: it challenges our assumptions about what robots should look like. Most robotic locomotion research focuses on biomimicry, trying to recreate how animals and humans move. But Sripada and Warrier note in their research that robots operating in human-engineered environments might actually benefit from non-anthropomorphic forms. Why make a robot look like a person when you can make it look like an alien geometry problem that somehow solves itself?

The implications reach beyond just being a really awesome tribute to a beloved sci-fi film. This kind of adaptable, multi-terrain locomotion could have real applications for space exploration. NASA and planetary robotics programs are always looking for designs that can handle unpredictable alien landscapes. A robot that can walk carefully across rough terrain, then transform into a wheel to speed across flat surfaces? That’s the kind of versatility you want on Mars or the Moon.

There’s something refreshing about TARS3D’s existence in our current robotics landscape dominated by humanoid bots trying to walk like people or dog-like machines trotting around warehouses. This project reminds us that inspiration can come from anywhere, even a fictional robot from a movie about wormholes and time dilation. And sometimes the best solutions don’t look like anything nature ever designed.

What Sripada and Warrier have created proves that with enough engineering know-how, determination, and probably more than a few late nights, you can turn movie magic into reality. TARS3D might not crack jokes about its humor setting being at 75%, but watching it transform from walker to roller is its own kind of entertainment. Science fiction has a way of becoming science fact when the right people decide to make it happen.

This First-Response Drone’s Bladeless Design Could Change Emergency Rescue Forever

Posted on by

You know, we see a lot of drone concepts float across our screens, and most of them look like they were designed by either the military or an insect. They’re all sharp angles, matte black paint, and an unnerving number of sensors. Then you see something like VITA, an EMS drone that just won a Red Dot award, and the first thing you notice is that it has a face. A simple, friendly, almost disarming little face.

And that’s the whole point. It’s literally user-centric, given that this drone was designed as a first-responder aerial unit. If this thing is going to land at a chaotic accident scene, the last thing it should do is add to the panic. The designers clearly thought about the human side of the equation. It’s a little detail that tells you everything you need to know about the project’s philosophy: this is about making high-tech emergency care feel helpful, not hostile.

Designer: Hongyi Sun

That friendly face is doing some heavy lifting. Imagine you’re at the scene of an accident; you’re disoriented, maybe hurt, and suddenly a machine descends from the sky. If it looks like a weaponized hornet, your instinct (fueled by hundreds of sci-fi movies) is to back away. But if it looks like a helpful little robot from a movie, you’re far more likely to approach it. This is functional empathy built right into the industrial design. The goal is to get people on the ground to trust it instantly, so they can follow instructions from a remote paramedic or grab the life-saving equipment it’s carrying without a second thought.

The cleverness doesn’t stop at the surface. The design backs up that friendly promise with some serious safety engineering. VITA uses ducted fans instead of the exposed, spinning blades we see on nearly every consumer drone. This is a massive deal. It means you, or a first responder, or even a child, could walk right up to it without the risk of getting seriously injured. In the unpredictable environment of a crash site, where people are moving around and debris is everywhere, eliminating that obvious hazard is a non-negotiable feature. It’s the kind of practical, real-world thinking that separates a cool render from a viable concept.

When you see the renders showing VITA being held in one hand, it all clicks into place. This isn’t some huge, intimidating aircraft; it’s a nimble and accessible tool. It’s small enough to get into tight spaces between cars and light enough for anyone to handle. Every element, from the approachable face and safe rotors to its compact size and clear markings, works together to serve one mission: delivering critical aid as quickly and safely as possible. VITA isn’t just another concept for a delivery drone; it’s a cohesive vision for how we can design automated systems to work with us, not just for us, especially when it matters most. That’s what makes it stand out.

This Robot Changes Shape to Match Any Terrain You Throw at It

Posted on by

Imagine a robot that can’t decide whether it wants to be a dog or a person, so it just becomes both. That’s essentially what Hong Kong’s Direct Drive Technology has created with the D1, a shape-shifting machine that’s making waves in the robotics world.

This isn’t your typical tech demo that looks cool but has zero practical use. The D1 is a seriously clever piece of engineering that addresses a real problem: different terrains require different types of movement. Need to haul something heavy across rough ground? The D1 becomes a stable four-legged robot that can carry up to 220 pounds without breaking a sweat. Got a narrow hallway or smooth surface to navigate? It splits into two sleek bipedal units that roll along at speeds up to 7 mph.

Designer: Direct Drive

What makes the D1 truly fascinating is its modular design philosophy. Rather than trying to create one robot that does everything mediocrely, Direct Drive Technology took a different approach. They built two independent bipedal robots that can operate solo or dock together to form a quadruped when the situation demands it. It’s like having a transformer that actually serves a purpose beyond looking awesome in action sequences (though it does that too).

Each half of the D1 weighs about 54 pounds and runs on a lithium battery that provides over five hours of operation per two-hour charge. The brains behind the operation is a Jetson Orin NX 8GB processor running Ubuntu, which enables both remote control and autonomous decision-making. This means the D1 can figure out on its own when it needs to split apart or come together based on what it’s facing.

The real-world testing footage shows the D1 tackling scenarios that would trip up most robots. In one clip, it takes a nasty fall on rough terrain but recovers its balance with the kind of precision that makes you wonder if someone’s secretly controlling it. Another scene shows it rolling across water without losing its footing, which is the kind of versatility that could make this robot genuinely useful in disaster response, industrial inspection, or military applications.

What’s particularly smart about this design is how it leverages the strengths of both biped and quadruped configurations. Four-legged robots are notoriously stable and excel on uneven surfaces, which is why we see so many robotic dogs being developed for rough terrain exploration. Meanwhile, bipedal robots are typically lighter, more compact, and better suited for flat surfaces where speed and efficiency matter more than stability. Direct Drive Technology essentially looked at that trade-off and said, “Why choose?” The result is a robot that doesn’t have to compromise. When it needs to be a scout vehicle patrolling smooth terrain, it operates in its speedy biped mode with wheels. When stability and payload capacity become priorities, it transforms into a sure-footed quadruped that can handle chaos.

The timing of this innovation is interesting too. As robots move out of controlled factory environments and into the messy real world, adaptability becomes crucial. A delivery robot that can handle both indoor corridors and outdoor terrain without needing two different machines makes a lot of economic sense. The same goes for search and rescue operations where conditions can change dramatically within a single mission.

Direct Drive Technology is calling the D1 the world’s first fully modular embodied intelligence robot, which is a bold claim in a field that’s moving incredibly fast. But watching the demonstration video, it’s hard to argue with the innovation on display. This is a robot that fundamentally rethinks how we approach locomotion in machines. Whether the D1 becomes commercially successful or remains a fascinating proof of concept, it represents something important: a shift from specialized robots toward truly adaptable ones that can handle whatever environment you throw at them. And in a world that’s increasingly complex and unpredictable, that kind of flexibility might be exactly what we need.

Black Friday deals include this Roomba robot vacuum for only $130

Posted on by

Robot vacuums can be a huge help, keeping your floors clean regularly without much extra work on your part. Black Friday deals often include some of our favorite robovacs, and this year is shaping up to be no different. iRobot's entry-level Roomba 104 Vac robot vacuum is available for 48 percent off right now, bringing it down to a record low of $130. A number of other Roombas are on sale for Black Friday, too.

In iRobot's lineup of robot vacuums, the Roomba 104 sits on the low end, adept at vacuuming up dust and hair, but without the mopping ability of its more expensive Max, Plus or Combo counterparts. The Roomba 104 Vac makes for a great first robot vacuum all the same, though, because of its four levels of powerful suction, and easy-to-use app. Like iRobot's other vacuums, the Roomba 104 maps and navigates your home with LiDAR, which helps it avoid obstacles. And using the Roomba Home app, you can schedule it to clean specific rooms, and even spot-clean particularly dirty spots.

An earlier version of the Roomba Vac is Engadget's favorite budget robot vacuum, and you'll get the same great performance out of the newer Roomba 104 Vac. That includes a specialized brush for cleaning the hard-to-reach corners of your home, and also a charging dock that the vacuum can automatically return to once it's down charging.

This sale on Roomba vacuums comes at an admittedly difficult time for iRobot at large, with the company dealing with a serious financial shortfall as of its last earning statement. Regardless of what happens to iRobot, though, the Roomba 104 Vac's offline mode should mean that it can clean your home and charge itself without the need of an app or an internet connection.

DoorDash customers in Miami can now receive their food orders from robots

Posted on by

DoorDash is bringing its robot delivery service to Miami, following an initial rollout in Los Angeles and Chicago earlier this year with over 600 participating merchants. The company continues to work with Coco Robotics as part of its push towards a "muliti-modal system" that allows it to make human, robot and drone deliveries at scale.

As well as adding a third city to the initiative, DoorDash also now takes orders from DashMart, its delivery-only convenience store chain for groceries and household items. This means customers will receive robot deliveries from national grocers and retailers as well as restaurants. 

DoorDash has a dedicated robotics and automation division called DoorDash Labs, which is focused on forging new partnerships that allow it to meet increased demand with more environmentally friendly methods of delivery. Earlier this year it began operating drone deliveries in Charlotte with Wing, and as well as using Coco’s self-driving robots, DoorDash recently introduced its own in-house developed delivery robot called Dot.

Decidedly cuter than its Coco colleague, Dot is designed for quick neighborhood trips and is able to navigate roads, as well as bike lanes and sidewalks. Dot is currently being piloted in Arizona, and when rolled out more widely is expected to fulfill cheaper deliveries, with DoorDash ensuring its human staff that the robot will complement, rather than replace them.

With fully autonomous technology still in its infancy, lower-risk hyper-local deliveries are being explored by a number of food delivery companies that have traditionally relied on gig workers to fulfill orders. At the beginning of this year, GrubHub partnered with the autonomous robot delivery company Avride to scale up the latter’s existing robot delivery offering on college campuses including the Ohio State University.

DJI’s Latest Drone Was Designed To 3D-Scan Landscapes (And Maybe Find Hidden Treasure)

Posted on by

DJI just made professional-grade aerial LiDAR look affordable – for companies, governments, and organizations, at least. The Zenmuse L3, launched November 4, packs technology that would typically cost $150,000 to $250,000 into a $14,600 package that weighs just 1.6 kilograms. Its dual 100-megapixel cameras and laser system can map 100 square kilometers per day with centimeter-level precision – capabilities that open doors far beyond traditional surveying into realms like archaeological discovery and terrain analysis that were previously the domain of well-funded research institutions.

While the L3 targets professional surveyors, utility companies, and mining operations, the technology has captured imaginations far beyond its intended audience. DJI’s launch video has racked up over half a million views, suggesting that even those who can’t justify the five-figure price tag (like me, for example) are fascinated by what the system can do: strip away forest canopies with laser precision, reveal hidden terrain features, and create detailed 3D models of landscapes that might conceal everything from ancient ruins to forgotten infrastructure – or perhaps even treasure waiting to be discovered.

Designer: DJI Enterprise

So here’s the thing about LiDAR that makes it fundamentally different from just strapping a really good camera to a drone. Cameras see surfaces, whatever light bounces back to the lens. LiDAR shoots invisible laser pulses at the ground, measures how long they take to bounce back, and uses that timing to calculate exact distances. Fire enough of these pulses fast enough, in enough directions, and you’re essentially building a 3D point cloud of everything below you. The L3 fires up to 2 million laser pulses per second, which is an absurd number when you think about it. Each pulse that hits something creates a data point in three-dimensional space, and when you’ve got millions of them, you can reconstruct terrain with the kind of detail that makes traditional surveying look quaint.

What gets interesting is how far these lasers can actually reach. DJI claims 950 meters at lower pulse frequencies, which means you can fly this thing higher than most photography drones and still get usable data. Fly at 300 meters and you’re covering massive ground while maintaining accuracy within a few centimeters. That’s the kind of precision that lets utility companies inspect power lines without getting dangerously close, or lets mining operations map their entire site in a single day instead of sending survey crews out for weeks. The laser spot it creates is tiny, about 41mm across at 120 meters up, which is roughly the size of a golf ball. Smaller spots mean more precise measurements, and the L3’s spot is apparently one-fifth the size of what the previous model could do.

But the real party trick is how this thing handles obstacles like trees. When a laser pulse hits a forest canopy, it doesn’t just bounce off the first leaf it encounters and call it a day. Modern LiDAR systems can capture multiple returns from a single pulse. Think of it like the laser passing through gaps in the leaves, hitting a branch, continuing down, hitting more foliage, then finally hitting the ground. The L3 captures up to 16 of these returns, which is double what high-end professional systems typically manage. Every return gives you another layer of information about what exists in that vertical column of space. For someone trying to map terrain under dense vegetation, this is the difference between seeing a green blob and actually understanding the ground elevation beneath it. Archaeologists have used this exact technique to discover ancient Mayan cities hidden under jungle canopy, and while DJI isn’t marketing this as a treasure-hunting tool, the capability is absolutely there.

The dual 100-megapixel cameras add context that pure laser data can’t provide. Point clouds are incredibly accurate but they’re also just clouds of points, no color, no texture, nothing that helps a human brain quickly understand what they’re looking at. High-resolution cameras flying alongside the LiDAR capture regular photos that get mapped onto the 3D point cloud, giving you models that actually look like the real world. At 300 meters up, each pixel in those photos represents 3 centimeters on the ground, which is detailed enough to see road markings, individual shrubs, basically anything larger than a soccer ball. The system takes both types of data simultaneously, so you’re not making multiple passes or trying to align datasets captured at different times under different lighting conditions.

Traditionally, capturing LiDAR data was the easy part and processing it was where everything ground to a halt. You’d come back with terabytes of raw laser measurements that needed heavy computation to turn into usable maps or models, often requiring expensive software and workstations that could actually handle the processing load. DJI bundles their Terra software for free, no additional licenses, and they’ve optimized it so you can open massive datasets on fairly modest hardware. They’re also doing something clever with real-time preview, letting you see the point cloud data and take measurements while you’re still flying. You’re not waiting until you get back to the office to discover your flight parameters were wrong or you missed a critical area. That kind of immediate feedback changes how you approach the actual data collection because you can adjust on the fly instead of scheduling another expensive flight mission.

The whole package weighs 1.6 kilograms and mounts exclusively to DJI’s Matrice 400 drone platform, which is their heavy-lift enterprise model. You’re looking at around $34,000 for the complete system, drone included, which puts it firmly in the realm of business investment rather than hobbyist experimentation. But that price point is what makes this notable. Five years ago, getting this level of LiDAR capability meant spending six figures on specialized equipment. DJI’s approach has been to take technology that existed only in high-end professional contexts and compress it into something that mid-sized organizations can actually justify purchasing. A regional utility company, a municipal government, a decent-sized construction firm, these are entities that can suddenly afford aerial LiDAR when they couldn’t before. And apparently, based on those YouTube view counts, a whole lot of people who will never touch one of these systems are still captivated by what it represents. There’s something fundamentally cool about technology that lets you see through forests and map the world in three dimensions, even if the only treasure most users will find is more efficient powerline inspections.
