This automatic ball launcher was originally designed for dog training. Drop in a tennis ball and yell “Fetch!” The ball hits the switch, the motor pulls the arm, and off it goes. I made it of whatever I had lying around in the workshop and it’s driven by an old battery drill motor. After a spell of baseball practice use, it is now used by another happy dog & owner.
Did you use a PLC to control the timing of the system? I am looking to make something similar for my dog! Thanks!
I want make something like that to! Do you have any photo’s where i can see clearly how it works? That would help me a lot to start. Thx
