does anyone know how to build a sturdy ball thrower for my dog?

I have one arm an it hurts to much to use those plastic ball thrower using your arm need something that I can set it up to so I can go for the ball more then one or two times(very active dog).

I want to say something like a pneumatic potato gun...that is, I love ballistics and pneumatics.... My first thought was to suggest those plastic armature ones, but if your arm isn't up to it, then you need something mechanical. A tennis ball launcher (like a baseball launcher), using a motor, rubber tire (or tires) and a mechanism to insert the ball into the moving tire to cause it to launch...
