Robot Parts

Aristotle was wise to say, “The whole is greater than the sum of its parts,” and although robots can take a lot of parts, those parts can do great things when assembled into a functional robot.

We’re robot people and have been for decades. We know what it takes to design and build robots (thousands of robots actually). Whether you’re building your first robot or maintaining your hundredth, you need the right robot parts and you usually can’t get those at local hardware, hobby, or big box stores.

It’s safe to say that every part we offer is “battle tested” because we only offer parts that we’d put in our own robots.

We break down our robot parts into four categories:

  • Electrical Robot Parts – controllers, batteries, encoders, components, cameras, displays, etc.
  • Mechanical Robot Parts – chassis, wheels, treads, servos, mounts, brackets, and more
  • Robot Tools – tools to make building & maintaining robots easier (and more fun)
  • Misc. Robot Parts – everything needed to build robots not included in the other categories

We also offer robot kits with many of these parts bundled together, most of which we can assemble for you, as well as pre-built robots that offer a great number of uses.
