Description

RC servo motor is very popular in RC (Radio Control), and now it is widely used in robotics. Yet, as many of you may already know, standard RC Servo cannot rotate continuously, there is a limit of around 270º (or 180º). It is not suitable for mobile robots that need continuous rotation.

The problem is solved with this tiny modified FS90R. It is a standard-sized servo from FEETECH (formerly known as Fitec) specifically for continuous rotation. This is a 360-degree continuous rotation servo. Its operation is very different from that of a standard servo. Instead of going to a specified angle, this servo will be static at a 1.5ms pulse (a trimmer is included to tweak this), a longer pulse gives forward rotation and a shorter pulse give backward rotation.

The FS90R continuous rotation servo converts standard RC servo position pulses into continuous rotation speed. The default rest point is 1.5 ms, but this can be adjusted by using a small screwdriver to turn the middle-point adjustment potentiometer. Pulse widths above the rest point result in counterclockwise rotation, with speed increasing as the pulse width increases; pulse widths below the rest point result in clockwise rotation, with speed increasing as the pulse width decreases.

This robotics servo is compatible with Cytron Servo controllers:

Since it provides continuous rotation you might need the wheel for it.
