Prepare the Servos for Mounting
For all ActivityBot robots, whether you have High-Speed Servos with X-shaped horns (#900-00025) or Feedback 360° servos with O-shaped horns (#900-00360).
- Using the screwdriver that came with the kit, carefully remove the black screw from the center of each servo horn.
- SAVE THE SCREWS! You will need them again later.
- Pull each servo horn straight up and off of its servo spline, and set the horns aside.
