            My 1-year old dog is full of energy and loves to play. However, with the first 8 hours of my day spent in school, I wanted to build him something he could play with. That’s when I decided to build the dog ball launcher. My dog drops the ball into the plastic chute and the machines detects the ball, and launches it back out.

           As the machine is automatic, there is no need for anyone to be present! This robot was also the perfect excuse to implement sprockets and ratchet bearings while practicing my welding too.
