The parts behind the builds.

The same channels, brackets, and hubs our Education projects are built on — plus 3D printing on demand. Upload your own models and we'll print and ship them.

Material ecosystem

One hole pattern, endless combinations. Every part is designed to bolt into the same grid, so what you learn on one build carries straight to the next.

Structure

U-Channel

$8/ each

The backbone of the ecosystem. 16mm on-center hole pattern so every bracket and hub lines up. Sold in 3, 5, and 7-hole lengths.

Order

L-Bracket

$3/ each

90-degree bracket that ties channels together or hangs a component off the grid. The workhorse connector in every build.

Order

Flat Gusset

$2.50/ each

Flat plate for joining channels in-plane and stiffening a frame. Same hole pattern, infinite uses.

Order

Motion

Motor Hub

$6/ each

Adapts a motor output shaft to wheels, sprockets, and gears. Press-fit bore options for our standard gearmotors.

Order

Bearing Block

$9/ each

Mounts a bearing onto the channel grid for free-spinning axles and steering tubes. The heart of the swerve build.

Order

Bevel Gear Set

$14/ pair

Matched bevel pair for turning power 90 degrees. Hardened teeth for low backlash in drivetrains.

Order

Electronics

12V Gearmotor

$18/ each

Reliable brushed gearmotor with an encoder option. The default actuator for beginner drivetrains.

Order

Dual Motor Driver

$22/ each

Drives two motors with current sensing and a simple logic interface. Bolts straight to a flat bracket.

Order

Reflectance Sensor Array

$11/ each

Line-following sensor bar used in the Line-Following Rover guide. Mounts to a flat bracket at ride height.

Order

Kits

Tank Bot Starter Kit

$99/ kit

Everything the Tabletop Tank Bot guide calls for: channels, brackets, hubs, two gearmotors, a driver, and tracks. The fastest way to start building.

Order

Mini Swerve Kit

$249/ kit

All the parts for one Mini Swerve Module: swerve channel, bearing blocks, bevel set, motors, and a steering encoder.
