Robo-starfish learns about itself and adapts to injuries
I am walking strangely. About a week ago, I pulled something to my left ankle, which now hurts during the part of each step just before the foot leaves the ground. As a result, my other muscles are compensating for this to minimise the pain and my gait has shifted to something subtly different from the norm.

But we can get a sense of how hard it actually is by trying to program a robot to do the same thing. It’s far from straightforward. Robots have
