MIT's Cheetah robot is off its leash, running and jumping

Sharon Gaudin | Sept. 18, 2014

Kim noted that MIT's Cheetah has a smoother gait, is quieter and uses less energy than BigDog.

"Most robots are sluggish and heavy, and thus they cannot control force in high-speed situations," Kim said. "That's what makes the MIT Cheetah so special. You can actually control the force profile for a very short period of time, followed by a hefty impact with the ground, which makes it more stable, agile,and dynamic."

He added that a key robotics advance is the Cheetah's ability to balance itself while running and jumping.

Imagine being in a field and finding a rock, Kim said. "In this case, [the robot] can jump over it. The whole point of having legs is sending [the Cheetah] where a wheeled robot cannot go. A lot of cars go nicely on the road, but there are many things wheels cannot go over. With this we are realizing the actual function of the legs."
