The Gesture Replicating Robotic Arm

Abstract

The Gesture Replicating Robotic arm is a servo controlled robotic arm which replicates gestures in a three dimensional environment. It makes use of cameras which detect the motion of one's hand in three dimensions. The cameras provide frames as input to the software which performs segmentation algorithms like background subtraction, color detection and contour detection. Pixel to angle mapping gives the appropriate commands to the respective servo motors. Thus, replication of the human hand movements is done. The crux of the project is to create software which can detect hand gestures without any involvement of sensors like accelerometers attached to the human arm, with no involvement of artificial intelligence. Thus it can avoid large blocks of code to perform a simple function which humans can perform easily like pouring coffee into a mug. That is robots will be able to move like people and they don't need to be intelligent. Such lifelike robotic arms can be tele-operated to protect human workers in hazardous environments, such as on assembly lines, in space, undersea, and amid nuclear radiation.
