Micro 360 Degree Continuous Rotation Servo
- Brands Feetech Code: FS90R
Note:Â Servo's warranty period is 3 months from the purchase date.
Â
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, a 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.
Â
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.
Â
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.
