Large, fast-moving robots are common on manufacturing floors, but people seldom work next to them for safety reasons. Some jobs, however, require people and robots to work together. For example, a person hanging a car door on a hinge uses a lever to guide a robot carrying the door. Using arm sensors that can “read” a person’s muscle movements, Georgia Institute of Technology researchers have created a control system that makes robots more intelligent. The sensors send information to the robot, allowing it to anticipate a person’s movements and correct its own. The system is intended to improve time, safety, and efficiency in manufacturing plants.
