Augmenting Your Hand with Two Robot Fingers
I missed this while at Comic-Con, but a cool example of one of the many human-robot interaction experiments being conducted at MIT: "Researchers at MIT have developed a robot that enhances the grasping motion of the human hand. The device, worn around one's wrist, works essentially like two extra fingers adjacent to the pinky and thumb. The robot, which the researchers have dubbed "supernumerary robotic fingers," or "SR fingers," consists of actuators linked together to exert forces as strong as those of human fingers during a grasping motion."
