pneumatics or motors?

Using a pneumatic cylinder to push balls directly will be disappointing, given the equipment legal on an FRC robot.

In Breakaway, many teams kicked the soccer ball using latex tubing to power the kicking 'leg, and then used a cylinder to reset the 'leg'. A latch held the 'leg' in place until the driver decided to kick again.

In Aim High, the more successful robots used a spinning wheel, like a baseball pitching machine uses, to launch balls. A well-designed mechanism was extraordinarily repeatable, but that is difficult to actually do, since the wheel wants to slow down as its momentum gets put into the ball.

Don't be afraid of pneumatics, but please read the rules very carefully to make sure your robot uses ALL of the safety equipment properly. This includes the 120 PSI relief valve*, the pressure release valve, the pressure switch**, the primary regulator, both pressure gauges, and the cRio and a Spike to control the compressor.

*This is supplied uncalibrated, be sure to calibrate it before use
** This is wired to a digital input of the digital sidecar. That signal is used by the cRio to control the Spike relay controlling the compressor.
