I just thought of an idea, haven't had time to try it out but here it is.
What if you were to have a sliding worm gear that would wind the arm up when
the motor was powered forward and release it when the motor was powered
reverse.
Like I said, just a thought.
Hope this helps
Scott

| Quoting scott davis <rcx2man@hotmail.com>: (...) Some of my students did this very thing. They used one motor to wind up a spring which was then released to kick a ball. Worked well. Bruce (21 years ago, 27-Jun-03, to lugnet.robotics)
