By growing the mushroom’s mycelium into the robot’s hardware, researchers have engineered two types of robots that sense and respond to the environment by harnessing electrical signals made by the fungus. =================================================================== A wheeled bot rolls across the floor. A soft-bodied robotic star bends its five legs, moving with an awkward shuffle. Powered by conventional electricity via plug or battery, these simple robotic creations would be unremarkable, but what sets these two robots apart is that they are controlled by a living entity: a king oyster mushroom. By growing the mushroom’s mycelium, or rootlike threads, into the robot’s hardware, a...
