Where can I get parts?

This page is a list of various bot related vendors and parts you may wish to purchase as you advance in robotic sports.

Please note: The listing here is a sample guide only and is not intended to endorse any specific products or websites. Please research and review each item before you decide to buy.

Part Vendors

  • Amazon.com – Great place for cheap DC brushed or brushless motors, electrical wire, wire connectors, switches, remote control transceivers, and various other gear. They have a large selection but you may not find everything you need here.
  • eBay.com – Great place to find all sorts of items. I primarily use it to find various metals and plastics that are hard to find on other websites. (e.g. 1mm thick titanium plates, carbon fiber tubing, aluminum blocks, etc.) They do also have all sorts of motors, wheels, and other bot related components.
  • Robotshop.com – Great place to find all sorts of items specifically related to robotics. I usually go here to purchase electronic speed controllers and other very robot specific items.
  • Mcmaster.com – Mcmaster-Carr is a well known and established company which sells just about any gear, drill bit, coupling, shaft, belt, or other mechanical component you can think of. It is not robot specific. If it’s mechanical and you can’t find it anywhere where, you can probably find it here.
  • HobbyKing.com – Great place for LiPo batteries, battery chargers, and other various RC hobby components.
