A robot that senses hidden objects

MIT News  April 1, 2021 Using RF researchers at MIT have designed, implemented, and evaluated RF-Grasp, a robotic system that can grasp fully occluded objects in unknown and unstructured environments. It can identify and locate target objects through occlusions and perform efficient exploration and complex manipulation tasks in non-line-of-sight settings. It relies on an eye-in-hand camera and batteryless RFID tags attached to objects of interest. There are two main innovations: (1) an RF-visual servoing controller that uses the RFID’s location to selectively explore the environment and plan an efficient trajectory toward an occluded target, and (2) an RFvisual deep reinforcement […]
