Robots are already being used in many manufacturing environments around humans. This video shows a gesture & speech-based approach to collaboration with a Baxter robot. The robot picks parts from the feeder, holds them in place, allowing the operator to screw.
The operator can ask the robot for a specific part or to hold parts at a specific angle. The robot can be controlled using voice commands and gestures. A Kinect 2 sensor is used for gesture and speech recognition.
