How they steer

Four ways to steer a brick machine: which motors turn which way, which boards drive them and which program to download.

TracksOne motor per track: one slower curves, one against the other spins on the spot.Building:bit tank, Wukong tanks, caterpillar tripod

Steered wheelsA servo turns the front wheels, like a real car.Steering car

Mecanum wheelsRollers at 45° on four motors: drives, turns and slides sideways.Wukong mecanum racer

LegsCranks swing the legs; one motor per side turns.Robot dog, hexapod robot, walking robot, spider walker, crawler

Boards

A board is what the motors plug into. Today our machines use a micro:bit on an ElecFreaks Wukong or a Yahboom Building:bit board; LEGO's own hubs and BuWizz are next.
