Hey guys so we are a rookie team from Calgary we have a question.

Are electric cylinders allowed on the FRC robots?

What is an electric cylinder? maybe if you provide a link to one for sale, or a picture, or a description, or a part number and manufacturer we could help you figure out which rules might apply

No, electric cylinders incorporate a motor that isn't one of the limited allowable motors.

See R32 for the only motors and actuators permitted.

Do you mean a linear servo? If so, I think there is a limit of 48oz/in torque for servos.

There's nothing in the rules against using a linear actuator, but you will have to replace the motor on the actuator with one of the legal motors.

Electrical actuator as per page 12/27 on section 4 of the manual….is acceptable as long as it has 1 inch stroke and not greater then 10 watts. We are proposing using an electrical cylinder which would conform to the above and would function in place of an air cylinder.

Is there an echo in here?

As long as you bring documentation to the Robot inspectors that fit the game manual description and can be proven by the specs to comply.

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

Generally, electric cylinders are not considered to be solenoid actuators, because as motors their extensions are adjustable. Solenoids have only two positions.
