FEETECH FS90R Micro Continuous Rotation Servo

The FS90R is a micro servo that has been built by FEETECH (formerly known as Fitec) specifically for continuous rotation, offering an inexpensive and easy way to get your small turret spinning or miniature robot moving.

FEETECH FS90R Micro Continuous Rotation Servo

The FS90R is a micro servo that has been built by FEETECH (formerly known as Fitec) specifically for continuous rotation, offering an inexpensive and easy way to get your small turret spinning or miniature robot moving, especially when paired with our 60×8mm wheels designed specifically for this servo.

Key specs at 6 V: 130 RPM (no-load), 21 oz-in (1.5 kg-cm), 9 g

The FS90R is a micro-sized servo that has been built by FEETECH (formerly known as Fitec) specifically for continuous rotation. At 6 V, it has a maximum rotation speed of around 130 RPM (no-load) and can produce up to 21 oz-in (1.5 kg-cm) of torque. The servo can be controlled using a direct connection to a single microcontroller I/O line without any additional electronics, which makes it a great miniature actuator for beginner robotics projects; just throw on a pair of wheels and your robot is ready to roll!

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.

The servo has a 7″ (180 mm) lead that is terminated with a JR-style connector and includes additional servo horns and mounting hardware. The following picture shows an example of the hardware that might be included (actual hardware could vary):

This robotics servo, which is a continuous rotation version of the FEETECH (Fitec) FS90, is compatible with our servo controllers. 

Note: As of December 3, 2014, we are shipping V2.0 of this servo, which widens the deadband from ±5 μs to ±45 μs to make it easier to set a stationary neutral position. Also, the middle-point adjustment potentiometer has been changed to a lighter SMD potentiometer on the new version. The physical dimensions of the servo have not changed.

Wheels

If you want to use this servo as an actuator for your miniature robot, you will need a wheel to go with it. Fortunately, we carry a 60×8 mm wheel specifically designed for use with this servo:

The wheel size is well matched to the servo’s speed and torque, allowing for a top speed of around 40 cm/s (1.3 ft/s) at 6 V.

Note: Wheel not included.
