Summary
Episode 22: What happens when you put several small self-propelled robots together in a corral? Physicists from Bordeaux studied roach-bots and found that above a critical number, the bots split into two groups: one that behaves like a gas and one that clusters along the boundary. When applied to a mobile corral, this phenomenon enables the bots to move the corral around obstacles.This could lead to new ways of cleaning and exploring, using robots.
