Build a fun little guy that can roll around on the floor! (You might want to apologize to your cat.)
1 Gather your Cubes, LEGO®s, and other materials.
2 Press the Battery Cube on top of the Motor Cube.
3 Press the 4-stud beam under the drive-side of the Motor Cube, and press the 12-stud beam to the other side of the Motor Cube.
4 Press the 8-tooth gear to the motor shaft. Press the 24-tooth gear on so the axle is flush with the gear face, and slide the wheel onto the other side.
5 Put another wheel against the 24-tooth gear, then switch the Battery Cube on and let your Circle Stepper start stepping!
