The robot arm has 7 servos including the one for the X axis of the camera. The robot arm has a camera mounted on top of the claw and it tracks movement. The robot will say that you have been tracked when the subject is tracked by the camera and say goodbye when the subject cannot be tracked anymore. I included 3 basic scripts to manipulate the robot arm.

In the next version, the script will guide the robot arm to the object with the camera tracking movement and it will grab the object.
