This chapter was about building a face tracker using a webcam and Dynamixel motor. The software we used was ROS and OpenCV. Initially, we saw how to configure the webcam and Dynamixel motor, and after configuration, we were trying to build two packages for tracking. One package was for face detection, and the second package was a controller that can send a position command to Dynamixel to track the face. We have discussed the use of all the files inside the packages and did a final run to demonstrate the complete working of the system.
