Redesigning LEGO Vehicles to Climb Ever-Higher Walls

Remote control LEGO vehicles can do some amazing stuff. Can they climb walls? In this video, the guys at Brick Technology start small, but then attempt to climb ever taller walls. For each LEGO wall, they begin with failure. But we see how they quickly identify the problem, and redesign the vehicle to fix it. Bigger wheels. Lower axles. Greater length. Adjustable weigh distribution. For each extra layer in the wall, the vehicle gets bigger and more elaborate, until the later models look more like robots than vehicles. The last version, challenged to climb a wall 40 brick tall, might remind you of a medieval war machine. They had to pull out all the stops for that one! (via Geeks Are Sexy)
