A miniature cheetah robot created at MIT has broken a personal speed record. He accelerated to 14.04 km/h
The mini cheetah is not the fastest four-legged robot.In 2012, its larger cheetah brother reached a top speed of 45.5 km/h. But the new mini cheetah, developed by MIT's AI Lab and the National Science Foundation's Institute for Artificial Intelligence and Fundamental Interactions (IAIFI), is much faster and able to learn on its own.
Typically the robot's movement is controlled by a systemwhich uses data based on the analysis of the movement of mechanical limbs. It creates models that the robot focuses on. However, they are often ineffective and inadequate, the authors of the development note.
In recent experiments, a four-legged robotcrashed into obstacles and recovered and ran with one leg disabled (she simulated a situation with a severed limb). It also adapted to slippery, icy terrain and raced over loose gravel hills. This adaptability is achieved thanks to the neural network. She evaluates new situations that could put her hardware under a lot of stress.
