How MIT helped a blind robot teach itself to walk in 3 hours: The key: removing humans from most of the process. And: extensive use of simulation.
TechFirst with John Koetsier: How MIT's Cheetah robot teaches itself to walk in 3 hours on Apple Podcasts
It may not sound very fast, but it is a record for this particular robot. Which, after all, only stands about a foot high and weighs about 20 pounds. Scale up the size, MIT grad student Gabriel Margolis says, and you’ll scale up the speed. Meaning, if they want to beat Usain Bolt and not just granny in her wheelchair, they can.“All of the behaviors that we’ve shown have been achieved, essentially, blindly,” Margolis says.
This gives the Cheetah the sense of what surface it’s on: whether snow or ice or concrete or grass or gravel, and the Cheetah adapts its method and speed of locomotion accordingly. “They can go a lot of places that wheeled robots can’t,” Margolis says. “We can have emergency response vehicles that actually come into a home and save someone. We can have delivery services that bring something up your stairs onto your porch or even into your house.”
