When you go to catch a Frisbee, you don’t need to stare at your hand until it makes contact. You have an intuitive sense of where your arm is—and where it’s going—based on how your muscles and joints feel. This sense of body position, known as kinesthesia, has proved tricky to build into prosthetic arms.
