These Swarming Robots Can Avoid Collisions with Each Other
Score another victory for robot-kind. A system which coordinates swarms of robots to avoid colliding with one another has been developed by a team at Georgia Tech’s GRITS Laboratory. The Safe Swarm Robotics system works by adding minimally invasive safety controllers to the robots, and it can prevent collisions in a large groups of robots that are working together. Thank God robot accidents will be down from now on.
The system works for ground-based robots and flying drones too. It not only prevents them from crashing into each other, but it can also detect other obstacles like a non-integrated robot, human, or animal and avoid them too. Which is interesting, because I thought for sure, it wouldn’t care about humans or animals. I don’t trust that.
Seriously, this is pretty cool tech. Check out the videos to see how robots coordinate to avoid colliding.

1,024 Robots Form Shapes: Art of the Swarm
We’ve seen dozens of small robots create structures and light shows. Harvard University’s Self-organizing Systems Research Group recently upped the ante with a swarm made of 1,024 robots called Kilobots. According to New Scientist, which shared a video of the collective, this is the world’s largest robotic swarm. And they didn’t need a single overlord.
The Self-organizing Systems Research Group created the Kilobots to “investigate algorithms for robust collective behavior, such as collective transport, human-swarm interaction, and shape self-assembly, as well as new theory that links individual robot capabilities to acheivable swarm behaviors.”
The video below shows Kilobots autonomously forming shapes, organizing from four base robots outward, layer by layer until the shape is formed. The robots are as slow as they are numerous though, practically taking half a day to form a single shape.
It looks like robots could wipe out humanity by boring us to death. You can buy Kilobots from K-Team or use the research group’s documentation to create your own.

Foursquare Gets a Facelift, Focuses on Personalization
A couple of months ago, Foursquare decided to create the Swarm app for checking-in and displaying nearby friends. The most recent update removes the check-in functionality of the main app and concentrates on making Foursquare a more personal experience.
Foursquare started in 2009 as a game. You could let the entire world (or just your friends) know where you are at a particular moment, and the more places you checked-in, the more points you obtained. Racing with friends to obtain supremacy week after week, or becoming the mayor of a particular spot was very fun, and actually encouraged you to visit more places or to become a regular in a location of your choice. This year, in May, Foursquare decided to focus on reviews, and created another app for checking-in, while still retaining some of that functionality in the main app. The new Foursquare, however, has none of that functionality, comes with a new logo, and made a goal from providing personalized recommendations of places you might like.
With the new update, the recommendations are tailored according to each user’s taste. As soon as the users “add tastes, follow experts, or even just walk around for a few days,” the app starts getting an idea about what other places they would like to visit. Foursquare and Swarm now complement each other perfectly, but can be used independently, as well.
Foursquare is also proud of its ever increasing userbase. In its most recent blog post, the company announced that it went past the 50 million user threshold, which is pretty impressive, considering the somehow limited functionality that this app used to have prior to the split.
Locations used to be the most important aspect about being a Foursquare user, but now communities have a lot more emphasis. It’s important what others think of a place, and it’s equally important who you’re tagging while checking-in. What some users don’t realize is that Foursquare is an ideal tool for keeping track of the places you’ve visited, especially if you’re in a foreign city or country that you might visit again in the future. Knowing where you felt good or bad will definitely help you make better decisions in the future.
