Major Components

See details for the major components:

  • Antennae - there are 3 antennae on the top
  • Head
  • Black neck ring - this contains LEDs on some sides. The blue one is "front" on the movie droid for operator reference.
  • Body
  • Skirt
  • Faux wheels - each corner has a small black 88.9mm diameter ball pretending to be wheels. In practice they sit a few mm above the floor.
  • Lego Greebles! - Yes, Lego! The bottom black details were created from Lego, then molded and cast in lightweight resin. Each of the 4 sides is theoretically identical, though I notice the seems in the corners don't fit perfectly on the movie model.
  • Holonomic drive - the movie droid has 4 omniwheels arranged so that it can rotate in place and move in any direction. Allows interesting movement and makes it fun to drive.

Electronics

Omniwheel Hardware

The motors mentioned above have to connect to the wheels. There may be a better way to do this than the parts kresty used:

  • 4 Omniwheels 4" or 100mm - Shawn used VEX 276-2185
  • 4 Square Shafts for Omniwheels, 2" long is OK (if using the VEX omnis)
  • 4 Couplers (connect square shaft to 47D shaft)
  • 8 Bearings (for square shaft, I used standard 608 bearings and printed spacers)
