Blind robot learns to walk on its own in record three hours

The Biomimetics Laboratory at the Massachusetts Institute of Technology (MIT) introduced a high-speed

robotic mini cheetah.The researchers didn't teach it specific movements, but the blind device learned to walk on its own and then broke the speed record for such devices. It reached a speed of about 14 km/h.

Usually, in the process of training robots, they examinereal system and create a similar model manually. But for such training, about 100 days of intensive work are needed. This is the time that a person needs to spend to create models and correct errors.

Reducing training to three hours required bothmethodology changes, and the use of simulators based on NVIDIA technologies. The application of this method implies giving up control of the robot's actions and giving it freedom to create its own actions.

The new simulator is a safe gamea platform where the robot can stumble and fall. So the device moves faster and more intensively, and also learns from its mistakes. The key point of the project was simulation and the ability to make mistakes without consequences.

The MIT Team Created a Behavior Improvement Methodrobot through simulation experience. This turned out to be extremely important for the application of learned behaviors in the real world. Now the mini cheetah can run as fast as a human.
