The bot recently unveiled by Klaus-Peter Zauner of the University of Southampton, is controlled by a bright yellow slime mold. The single-celled organism naturally moves away from light and toward moist places, and is able to control a six-legged robot when light was focused on a sensor. Since the slime mold is able to grow to several feet in size, we assume Zauner is working on applications that go far beyond the lab, which will inevitably result in a light-controlled slime-bot army.
