A compact three-layer round robot chassis kit with two DC drive motors, matching wheels, and a caster ball for balance. The high-strength anodised aluminium alloy frame provides a sturdy platform for building your own 2WD mobile robot, with three layers of mounting space for batteries, controllers, and sensors.
The differential drive design (two independently driven wheels) allows a near-zero turning radius, making it ideal for navigating tight spaces on flat indoor surfaces. You'll need to add your own power supply, microcontroller, and motor driver to complete the build.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
