Hi!
we are really new to all of this and are in great need of some assitance!! Our competition is fast approaching and we need to figure out how to convert our servo motor into a continuous motor. We’ve already taken out the geared brake in the servo, but the motor is continuously spinning afterwards and fully uncontrollable by our remote. It just keeps spinning!! Is there anyway to solve this!!
Please help!!
Even if you can work out a way to do this, I don’t think it’s FVC legal. Your best bet is to purchase another motor. If you need to sense the position of the motor, then use an optical shaft encoder.
I suggest http://www.vexlabs.com for vex parts.
11Ed71 is right, modifying an electrical component (such as a servo) in any way is a violation of FVC rules. If you need another motor, you’ll have to buy one. If you don’t need continous spin but just more degrees of rotation you could use gearing to accomplish that.
chances are the pot is stuck in one direction, causing it to continuously spin in that direction.
did you take out the pot? i’m aware of the fact that after fixing the servo mechanically-or removing the plastic stub piece that sticks out of one gear- you should replace the potentiometer with two 2.2k resistors.
the potentiometer has 3 pins. remove the wires from each pin(desoldering probably) and replace the outer pins with said resistors to the outer wires and the other ends of each resistor to the middle pin.
i may be a bit vague, but thats how I do it. i would just go with a normal motor if i were your team though, just to be safe.
