2000 oz-in and very, very, very slow rotation. Remember your limitation on servo power.

You need both speed and some power, so a servo probably isn't the device you want. You're saying a VEX motor doesn't have the power. Well, that leaves either a light Banebots or a small pneumatic cylinder. If you aren't otherwise using pneumatics, then the pneumatic cylinder is not going to help weightwise (because then you have to add a full system somewhere). That leaves a light Banebots motor (probably the RS395), or maybe some of the other lighter allowed motors.

Or... Wait, would a 1-inch throw electrical solenoid actuator work? How about a Denso throttle control motor? What about an AndyMark motor or gearmotor?

Could you post links to one of those 1-inch throw electrical solenoid actuators and Denso throttle control motors so I can research them?

Pneumatics is a waste for use to mount and barely use. And the bane bot motor weighs 12.4 ounces, and we need 2 for each side of the claw. That leaves barely any room for the actual parts (let alone the gearbox) because we're calculating a max weight of 3 pounds.

I guess this probably wasn't the right thing to ask because I can't provide too much information without saying our designs, but once I look at those two, I should be able to come up with a decision with the team! Thanks in advance!

I found both. They aren't what we need, but I think I'll stick with servos

Good luck then, and see you at the competitions.
