Vex Pro: Ball Shifter with a servo?

[jman4747]

I would say always leave yourself as many options as possible. The vary nature of the challenges we face each year constitute being able to use every tool at you're allowed. Even if you have no intention of using them the learning experiences and extra team building alone could be worth it.

As for solenoid actuator rules, "Electrical solenoid actuators, no greater than 1 in. stroke and rated electrical input power no greater than 10 watts (W) continuous duty at 12 volts (VDC) Unlimited" FRC Game Manual 2013

Electric solenoids probably aren't a great idea for shifting, as they will burn out if they are held in the same position for a long time. Also, I don't think that a 10W electric solenoid will have enough power to activate the shifting mechanism.
