Mini car
Yahboom Building:bit starter kit
A four-wheel car on the Yahboom Building:bit expansion board. Its two motor modules stand end to end and each drives one wheel through a 24-tooth gear, one on the left and one on the right, so the car steers by running the motors at different speeds. Turn it in 3D, build it step by step or open it in BrickLink Studio.
