Team 178 has had luck with the pneumatic punter. We tested a prototype that gave us a 17" push, divided into 3 stages, with (at least) 50 psi. When tilted (angle currently unknown) it was able to clear the truss and the high goal. Plus, it had enough air stored for two more cycles. Video has been recorded of these tests
and I will provide a link when available.
We've got more 8" pistons on the way so the above configuration is not final. If this does become part of our bot the students need to figure two things.
- Where to mount the completed mechanism on the robot
- How we can properly seat the ball in place for an optimal shot
EDIT 11:24pm: link to video highlighted above. Go to 10:50 in.
