up with a computer and then set it free. the flying robot uses the system to determine where it's flying, and how it can maneuver without running into things. look at that. that is way cool. and normally, when you think of a robot, there's usually a person running it, right? well, not this little guy. it is fully autonomous, which means it's able to run all by itself. so you just saw that robot flying around a room. this is how that room looks to the robot. so why would you want a little robot that can fly on its own? very good question. well, think military. imagine drones that are able to fly without maps or even gps. and yes, the army research office and the office of naval research actually funded this project to help build better drones. geeky, but cool. that's what we like to say. and in other big-i news, a new app for your smartphone uses your voice to sculpt three dimensional images. check out this video from construct. this company has created a way to utilize the camera and the microphone on your smartphone to create the 3-d sculpture.
