Engineers are racing to see who can create the toughest robot that can really take a beating. This quality is in high demand these days. In Tokyo, the Robust Humanoid Robot (aka RHP2) was built to take some serious punishment. It’s a human-sized, bipedal robot that is run by electric motors (soon to be a hydraulic system).
This robot is unique because it will always stand up again no matter how often it is knocked down. Like the film character Rocky said, “It ain’t about how hard ya hit. It’s about how hard you can get hit and keep moving forward.” Once knocked down, the robot pulls itself up again every time—just like a human.[
There is a lot of (expensive) damage that can happen to a robot when it topples over. Just like a cat has the instinct to right itself during a fall, RHP2 has been programmed to fall in a specific position. It’s also built with a metal frame to protect its innards.
