Here is your robot cat. Premium price, since it has no head

Ecole Polytechnique Federale de Lausanne’s (EPFL) four-legged “cheetah-cub robot” is an amazing robot, albeit not something new in the world of robots. From the looks of it this robot can run quite fast and it is robust (ca walk over minor obstacles). They observed the leg s a cat and tried to rpelicate it using three segments, springs replace tendons and actuators replace the muscles.

Not the springs, nor the actuators are the ingenious part here. The rule of thumb is to make the darn thing move and stay upright even on rough terrain. And to make it move fast.

Deceptions, charge!
