RC servo drive pack contains two servomotors RM-0090 and accessories for mounting servos on the chassis.


The RM-0090 is RC servo motor with bidirectional continuous rotation and linear response to PWM. The default neutral position is 1500 ± 50 us (1.5 ms), but this can be adjusted by sending an desired PWM width  (eg 1400 us) and holding the red button for 5 sec. 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.

Just attach a wheel and you have a mobile robot that can be controlled using an RC signal or a simple direct connection to a single microcontroller I/O line without any additional electronics. 

RM-0090 servo motor have three wires: black, red and white.

  • black = ground (GND, battery negative terminal)
  • red = servo power (Vcc, battery positive terminal)
  • white = servo control signal line


Key Features:

  • Bidirectional continuous rotation with linear response to PWM
  • Control interface: RC servo pulse width control, 1500 ± 50 usec default neutral position
  • Button for adjusting the neutral position
  • RPM : 0 to 71 (7.4 V) ; 0 to 62 (6 V)
  • Working torque: 9 kg•cm (6V) ;  10 kg•cm (7.4V)
  • Accepts four mounting screws
  • Metal Gear with Ball Bearing
  • Easy to interface with any microcontroller or PWM-capable device 
  • Very easy to control with PBASIC's or SX/B's PULSOUT commands
