Wheels: Plastic lids for the main wheels - diameter 114mm (I ended up using 66.4mm diameter lids as explained in Part 6 of this series)

Caster wheels: Joint rack (shelf) caster wheels - diameter 30mm (1.2 in.); bolt size M6: https://amzn.to/3Lo3pGc

Modified Servos: HiTec HS-311 servos (x 2), modified for continuous rotation: HiTec HS 311 servo: https://amzn.to/4cQbSO8
(see this video    • How to Modify a Standard Hi-Tech HS31...   to learn how to modify these servos )

Chassis Construction:
HDPE cutting board (typical kitchen cutting board)

Robot body material:
Tamiya Pla-Plate: https://amzn.to/3S7ASbr
