When talking about Servo, it's generally meant in the term of Radio Gear for RC hobby vehicles. A Hobby servo, which most of us here are familar with, uses a signal from the radio reciever, this is used in the onboard controller built into the servo. This then tell the servo where to be and when to be there. This is proportional control. A normal motor does not require this signal as a standard motor doesn't have the onboard controller. When we look at robots, we use speed controllers instead of an onboard motor controller, and we don't have a feedback loop to keep the motor in one place.

so what your saying is that the different thing about motors to servos is that a servos have a built in speed control?

Yes, but servos have a feedback looping cicuit in the controller that lets them go to a position and stay there, this is according to how far you push the radio transmitters stick. _________________ https://www.halfdonethings.com/

yeah ditto on that breaking servo leads business.
what would work to foruther prevent it as probably adding a small blob of hot glue to keep the wire close to the servo still to stop it twisting and wearing out.
I have one servo that needs fixing and another thats just about to break a lead. _________________ Andrew Welch, Team Unconventional Robotics
Yeah you should just be able to solder them back on if you are good enough. Make sure you don't end up with solder connecting points which shouldn't be connected and make sure the leads go on in the correct order. The glue might help if it could stop the wires moving near the solder joint. _________________ Steven Martin
