The Mechanical Hardware The CMUCAM is mounted on a platform connected to 1 servo. Thus it has a single degree of freedom. For its locomotion, Ouimet relies on 2 continuous servo motors setup in a differential configuration. Ouimet’s Golf Club is connected to its chassis by means of a micro-servo motor.

Algorithm Search for a white ball by executing random turns and straight line motion, with the camera pointed downwards. Once a white ball is detected align it in the center of the frame. Raise the camera to 0 o elevation and rotate till the flag(marking the hole) is located while measuring the angle of rotation.

Algorithm Once the flag has been and the relative angle between the ball’s location and the hole has been measured calculate the next steps of motion. ɸ d d1d1

Algorithm Align with the ball and the hole in a straight line and then putt the ball into the hole. Ouimet

Algorithm If the ball is visible repeat the process. Otherwise the objective has been accomplished! Ouimet

Behavior Flowchart Start Search for a white ball by moving randomly Ball detected ? Center the ball in the image Rotate and locate the flag Calculate the position of alignment, move to the same and putt the ball into the hole Is the ball Visible? End YES NO YES
