Robotic Control System to Improve Safety & Efficiency in Manufacturing Plants

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.

    00:00:02 When the robot detects that the person is trying to hold the device steady, it actually slows down the motion and adds damping into the system so that it moves more smoothly and is easier to hold in place when they need to. And then when the person relaxes again, and the robot detects that they're trying to move the device over a distance again, it then removes that restriction and will move quickly again. Basically, what we're doing is we are

    00:00:30 taking some sensor measurements of the person and trying to make the robot smarter. So, typically robots are designed just in a vacuum. The robot is designed as the robot and that's the way it works. But what we're trying to do is give the robot some knowledge of the people that will be using it to make that robot more intelligent and more user friendly.
