CyberBrick Modular Bricks Kart (Mecanum Wheel)

After the Modular Bricks Remote, I’ve been wanting to design other CyberBrick hardware into modular bricks. I believed a complete vehicle project would make this concept far more engaging, so lots of development work was required beyond designing basic modular bricks. The project is now finished — the Modular Bricks Kart, available in the Mecanum Wheel Version. Mecanum wheel vehicles are incredibly fun. They can drive like ordinary cars and also perform omnidirectional lateral sliding.

Modular Bricks feature easy assembly and disassembly, allowing quick swapping between different toy models. Even children can assemble them with little difficulty. Once you have the full set of basic modular bricks, assembling any subsequent model becomes quick and hassle-free. This kart adopts exactly this design. Except for the wheels, the entire chassis and body require no screws or adhesive — assembly is just like stacking building blocks.

It’s compatible with the official standard remote. 

If you are interested, I recommend trying my previously released Modular Bricks Remote, which lets you own a full set of modular brick toys. Some future models will rely on the unique advantages of the modular brick system to deliver functions unavailable with standard remote controllers.

The remote links are in the Assembly Guild.

Controlling a Mecanum wheel vehicle normally requires four motors, yet the CyberBrick receiver only supports two. Fortunately, it comes with four servo ports, so I opted to use four servos for power. This setup allows full vehicle functionality with a single receiver unit, while servos also deliver superior torque output.

·Download the assembly guide for detailed build instructions, covering three manuals: Basic Modular Bricks, Chassis and Body, Mecanum Wheels.

·The printing profiles are split into three sets matching the assembly guides; all three must be printed. Layouts are optimized for the A1 mini 3D printer and compatible with all other printer models.
