The 2015 list of legal motors includes Electrical solenoid actuators with a specific limited power and a specific limited stroke length. I am absolutely certain that stepper motors are not, nor do they contain, solenoid actuators.

If I were inspecting a robot and found a stepper motor, I would not consider it legal. If a team tried to argue that stepper motors are just solenoids in a certain arrangement, I would tell them they are entitled to present their case to the Lead Robot Inspector.

If I were the LRI and a team tried to make that case to me, I would give them a yellow card for egregious attempted lawyering.
