Click here to view the full project report.
My 1-year old dog is full of energy andloves to play. However, with the first 8 hours of my day spent in school, Iwanted to build him something he could play with. That’s when I decided tobuild the dog ball launcher. My dog drops the ball into the plastic chute andthe machines detects the ball, and launches it back out.
As the machine is automatic, there is noneed for anyone to be present! This robot was also the perfect excuse toimplement sprockets and ratchet bearings while practicing my welding too.
