Hello,

I have units that requires frequent series knob rotation (volume) & push button with more precision, can anyone advise should i go with Robotic ARM or any suitable servo motor.

Also kindly help with any references to start with both Robotic & Servo.


Thanks
Hussain
 

I do not think robotic arm with serve your purpose correctly. If you want to rotate knob I guess servo motor is the right option. I am not that professional I am just a programmer. I have seen projects like this and with that experience I am suggesting.
 

rotating a servo motor is just easy using a knobe (potentiometer use). but will also require mcu
with potentiometer divider.
 

I saw a hi-fi unit whose volume knob visibly rotated when you pressed the remote control. A little red led moved clockwise, counter-clockwise... It was like magic.

Inside was a small motor which dialed a potentiometer. RPM was stepped down either by gearing or rubber wheels.

A full H-bridge is the proper hookup so you can start/stop/reverse a small motor.
Or a half-bridge if you have dual bipolar power supplies.

Your control circuitry needs to respond immediately either:
* when it detects your commands
* when it detects certain condition
* when it is about to reach certain condition
