• Battery Cube
• Motor Cube
• Assorted LEGO® Technics
Circuit Cubes are perfect for making your building bricks do new things! Here we take Star Wars' popular Walker AT-AT vehicle and make it move.
NOTE: Steps 1–29 show you how to put together the Walker build. You can either follow along with our photos or use your favorite instructions to get it built!
Step 30 Stack the Battery Cube on top of the Motor Cube, attaching the gear to the motor.
Step 31 Place the Cubes on the Walker’s head as shown, being careful to align the gear so that its teeth mesh with the gear at the front of the Walker. Turn the Battery Cube on and watch your Walker go!
