I designed this Pan/tilt for use on my robot (FRED).

The pan base is supported by plastic bearings & the tilt servo is geared to the top shaft, rather than the more common direct drive.


The advantage of gearing the tilt is threefold:

  • Greater torque available due to 2.7/1 gear ratio,
  • Main shaft is supported by two ball bearings.
  • Servo backlash is reduced by factor of 2.7, less any slop in the printed gears (minimal)


The pan section is direct drive, but is supported by plastic bearings, removing excessive side loads from the pan servo.


Overall result is a strong & stable pan/tilt mount.


Control of the two servos is via RC interface or microcontroller.

This is my design & files have been shared on Thingiverse.


Please note: 

Nuts are provided in the tilt platform (3mm nylock), but no other hardware is supplied.
