MIT robot uses radio waves to find and retrieve hidden objects


MIT researchers have developed a robot that can detect and grab objects that are hidden behind walls or pieces of clutter. The system, called RF-Grasp, uses radio waves to locate items beyond the line-of-sight of a robot's cameras. It could help warehouse robots grab customer orders or tools that are occluded behind obstacles. If an object is concealed, they typically need to explore the environment and search for the item. Unlike visible light and infrared, RF (radio frequency) signals can traverse cardboard boxes, wooden walls, plastic covers, and colored glass to perceive objects fitted with RFID tags.
