original post »MIT researchers have released a video of a robot they're calling "cheetah" making its way across campus. An earlier robot that was also called cheetah was part of a DARPA/Boston Dynamics (now owned by Google) collaboration that was notable for its speed. The MIT version is notable for ditching the tethers that supplied power to it—it goes for runs using on-board battery power and control logic.
Cheetah is only able to move at up to 10 mph, but its developers expect that they'll be able to get it to eventually travel at up to 30 miles an hour. For now, cheetah's biggest accomplishment is being able to move without any wires, which are normally used to supply power, and in some cases command-and-control, to more sophisticated robots.
The MIT group has also been working on the mechanics of the robot's stride, trying to have it exert more force each time it strikes the ground. The result is that it's been able to move across less rigid surfaces, like grass, which is why it's able to be taken out onto the MIT campus. Additionally, they've developed a routine that allows the robot to take a hop, which will let it bound over obstacles.
