Robots are a major part of the cultural fabric of Japan; they’re performing weddings, buying groceries and keeping people company. A team of researchers at the University of Tokyo is taking this robotic cultural immersion a step further — they’re making animal-robot hybrids. Sort of. RatCar is a brain-machine interface that uses a rat’s brain signals to control a motorized robot. The rat hangs in the air, and the robot does what the rat’s limbs would do. It’s far from the only brain-robot locomotion contraption, but it’s arguably one of the strangest.
