Continuously Rotating Servo?

Our team prototyped a roller gripper using vex parts and it worked surprisingly well. I was astounded at how much torque those motors can put out.

Since we cant use the motors in our final bot I was wondering if it would be possible to modify a servo to spin continuously and still have it be legal under the rules.

I'm not sure if it would technically be a servo anymore if we did this.

But I found a nice guide on how to do it:

If it is illegal, are there any good alternatives? We are looking for something lightweight and compact.

Re: Continuously Rotating Servo?

You would have to disconnect the potentiometer. However, I'm not sure that modifying a COTS servo would be legal. Maybe try out a winch servo for RC sailboats. They will rotate up to 8 revolutions at a time.

Re: Continuously Rotating Servo?

There is a Tetrix piece of equipment called a continuous rotation servo.

I believe this is the same a a Vex motor module.

I'm guessing the Tetrix name qualifies it as a legal piece of equipment.

It doesn't necessarily.

Get a continuous rotation servo, as long as it's under 4W. I believe Hitec sells one or more.
