I have been out of FIRST for a couple of years and now mentoring a team. Can y’all help me a question we are having? We are hoping to have one solenoid activate 4 pistons to lift the bot (we are staying inside the bumper zone). Is that legal or do we have to have 4 solenoids?

You can connect the output of one valve to multiple cylinders. So that part would be legal. You just cannot connect the output of multiple valves together.
