Re: How do the Shooters work?
I guarantee we are the only catapult of our kind.
We use 4 springs, or about 300 pounds of force, to launch the ball. The springs are attached to a solid axle at the top, and to linear slider on the other side. A winch system using a custom gearbox for the van door motor, uses a ball lock mechanism to lock into place and winch the catapult back, thus tensioning the springs.
A limit switch tells the robot when we are cranked all the way back. We load up a ball and come around the track and hit the fire button, which engages the pneumatic piston that releases the ball lock and thus puts the gearbox into "neutral" allowing all the stored energy to be released. The results can be seen here at around 1:37 :
