MIT Robotic Cheetah

Quiet, efficient, and powerful: MIT’s robotic cheetah has a “custom-designed, high-torque-density” electric motor, and can run and jump around without being tethered to an external power source. It’s also looking to earn its name:

Description

MIT researchers have developed an algorithm for bounding that they've successfully implemented in a robotic cheetah. (Learn more: http://bit.ly/1CZToFe) The key to the bounding algorithm is in programming each of the robot's legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward. In experiments the robot sprinted up to 10 mph and MIT researchers estimate the robot may eventually reach speeds of up to 30 mph. The MIT Cheetah 2 contains the custom electric motor designed by Jeffrey Lang, the Vitesse Professor of Electrical Engineering at MIT and the amplifier designed by David Otten, a principal research engineer in MIT’s Research Laboratory of Electronics. This work was supported by the Defense Advanced Research Projects Agency.
