At some point in your life, you've probably used a combination of sight and touch to find something hidden beneath your couch cushions. And for a while now, robotics researchers have tried to give their creations that same capability. Back in 2019, a team of scientists from the Massachusetts Institute of Technology (MIT) used a combination of tactile sensors and AI to allow a robot to identify objects by touch. A separate group of scientists from MIT has now built a machine that can find things it can't see initially. The aptly named RF Grasp depends on a wrist-mounted camera and an RF reader to hone in and pick up an object.
