Description
This FS90R Mini 360 Servo by Feetech is a great value multi-purpose micro size servo and it's ideal for use with micro-controller systems like the BBC microbit, Arduino, Raspberry Pi and PICAXE. It's miniature size also makes it great for use in radio controlled models and small robot projects.
This is a 360 degree continuous rotation servo. Its operation is very different to 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 backwards 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.
It comes with mounting screws and a range of horns to suit most applications. You can use any servo code, hardware or library to control these servos, so it's great for beginners who want to make things move without the need for a motor driver board. These servos are fully compatible with our Servo:Lite board which is also included in the :MOVE mini buggy kit for the BBC microbit.

Q:
When connected to Arduino Uno, can we change the speed smoothly? (not only the direction at max speed)
A:
Hi Dim,
Thank you for your email, you could code in the arduino to gradually change the servo or set it to full speed in either direction.
Best Regards

Q:
What's the torque on these servos and any other servos you stock?
Thanks
Asked by: Adam
A:
Hi Adam,
Thank you for your email, the stall torque on our servos varies based on input power. This one goes between about 1.5KG/m to 1.8KG/m. We do have some more powerful ones which do around 4KG/cm at higher voltages.
Each of our servos should state these details under the technical information for you.
Best Regards
Cullen

Q:
Can this be configured to allow 360 degree rotation and STOP, with the next command being 360 degree rotation and STOP etc., etc., etc. ?
Asked by: Roy Stephenson
A:
Hi Roy,
Thank you for your email, theoretically you can with a micro controller running it. However whereas 180 degree servos provide themselves with feedback 360 degree servos do not so they would not know when they had come full circle. What you would need to do is roughly work out how long it takes to complete a rotation for example 2.5s. You would then programme the servo to turn but tell it to stop every 2.5seconds which should see it rotating 360 degrees and stopping. If you put this in side a loop command this should be able to go repeatedly.
I hope that makes sense!
Best Regards
Cullen
