| Some hobbyists realize RC-Servo motor,
which of cause used for RC-Car or RC-Airplane have positioning function
by itself. Addition to that, it is absolute positioning (not a relative
so not require calibration for start up). No feedback required, motor include
it with in. motor is relatively compact, small enough for hobby project,
gear reduction is also included, and large static friction hold the angle
even power is turned off.
I thought this is a perfect motor to use for my hobby robot.
It requires 1-2ms PWM signal to control RC-Servo angle. Just like this.
My idea start from this motor - I thought
it is possible to make handling robot by this motor so I tried.
