These Wheels Shapeshift for Different Terrain

Who says wheels need to just be round? These unusual Reconfigurable-Wheel Track (RWT) wheels were developed by CMU National Robotics Engineering Center for DARPA’s Ground X-Vehicle Technologies program.

We can expect to see these on the war machines of the future and they may be the next step toward real-life Transformers like Optimus Prime.

These wheels can morph from a round wheel to a triangular treaded track quickly, in less than a second, which makes the vehicle good for a wide variety of terrains. The round wheels are good for hard surfaces, while the triangular tracked wheel is good for softer ones.

It’s pretty impressive to see the wheels in action. I’m hope we see them on more military vehicles very soon, then one day hopefully our own civilian vehicles will have them as well. There’s certainly more that can go wrong with these wheels compared to what we are using now, but they provide a lot more benefits too.

It’s just a shame that they only show them working on a paved parking lot. I’d like to see how they perform and change while on softer ground. This makes me think that they may not be ready for prime time.

Three teams will compete for millions in DARPA’s rocket launch challenge

Despite all of the advancements in space travel, rocket launches are still hindered by the fact that they take months, if not years, to plan and execute. Because that could slow vital military operations, DARPA created the Launch Challenge: a call fo...

Android apps used by troops in combat contained vulnerabilities

Two Android apps used by the US military in live combat situations contained severe vulnerabilities that could have allowed attackers to gain access to troops' information, a Navy Inspector General report revealed. The mobile apps offered real-time m...

Centauro Robot is Part C-3PO, Part Centaur

While most visions of the future envision robots as looking like humans, they certainly don’t have to be. The funky looking robot you see her was designed to compete in the DARPA Robotics Challenge. Centauro isn’t your typically humanoid design. It does have two arms, a torso, and a head, along with four legs with casters as “feet.”

Those legs are key to the Centuaro’s prowess in the DARPA challenge as they each have six degrees of freedom. The legs can rotate the hips, knees, and angles and control the four-wheel modules individually. It can operate in a traditional quadruped configuration or in a spider-like configuration for stability when using tools.

The gold and black clad robot stands about 5 feet-tall, weighs about 205 pounds, and has enough battery power to run for 2.5 hours straight. Each of its arms is able to carry about 24 pounds. The gif above also shows that it can karate chop you in the head.

DARPA pushes for AI that can explain its decisions

Companies like to flaunt their use of artificial intelligence to the point where it's virtually meaningless, but the truth is that AI as we know it is still quite dumb. While it can generate useful results, it can't explain why it produced those resu...

DARPA’s wheel switches shapes with terrain!

Designed as a collaborative project between Carnegie Mellon University’s National Robotics Engineering Center and DARPA researchers, the Reconfigurable Wheel Track, dubbed the RWT, helps vehicles move on any sort of terrain… and it does so in spectacular fashion, by shapeshifting to turn from a rotary wheel to a track system.

On much harder terrain, the RWT works like a regular wheel, rotating to help move the vehicle from point A to B, but the minute it reaches terrain that’s softer, like mud, silt, snow, or sand, the RWT shapeshifts (within as quick as 2 seconds) to a triangular format, and the rubber grip around the tire runs like a conveyor track you’d see on tanks. The wheel ultimately allows vehicles to move around effectively, regardless of the terrain type or the weather, and will see itself being used on vehicles for defense purposes.

And while the GIF below definitely makes me go “whoa”, my favorite wheel reinvention will probably still be NASA’s incredibly light and versatile chain-link wheel.
