Hey all, this is the shooting mechanism for our robot. We maximized simplicity and efficiency in our build. Compliments and constructive criticism are appreciated.
I love that trigger mechanism! Awesome design guys!
How is the wear and tear on the boulders?
We ripped our first one 
You can definitely hear the wheels slipping on the ball in the first video. I would try to see if you can get similar results with less that what seems like full throttle. And I agree, the off center wheel as a trigger is genius.
I really like how smooth the arc is. How is your consistency?
