Brick Technology’s LEGO Vehicles Conquer Walls by Scaling New Heights, Literally

Brick Technology has turned LEGO into a playground for mechanical genius, building a series of remote controlled vehicles to tackle the challenge of climbing over increasingly taller LEGO walls. Each vehicle is built with precision and creativity and must drive smoothly before and after the wall and only use forward momentum to climb the wall, no steering.

The journey starts with a small car, a 4 wheeled creation powered by a Circuit Cube motor and a BuWizz 2.0 Bluetooth controlled battery box. It faces a low LEGO wall, barely a hurdle for its small frame. The car is designed to be simple: standard LEGO wheels, a compact chassis and just enough torque to roll over the wall. It works, setting the stage for what’s to come. This first success feels like a proof of concept, a baseline that shows potential but hints at the limitations of basic designs as the walls get taller.

A minute in and the challenge escalates as well as the vehicle. Enter the tank, a tracked beast built to grip and grind over a taller wall. Its LEGO Technic tracks provide more traction than the car’s wheels. The tank’s low center of gravity and continuous tracks allow it to climb and grind its way up and over, where the car would falter. Brick Technology’s decision to not use steering keeps the focus on raw climbing power and the tank delivers, proving that tracks can handle terrain that wheels can’t.

Skip just over the two minute mark and you’ll realize that the wall demands more than brute force and so the articulated tank is introduced. This vehicle refines the tank concept with a flexible chassis, split into segments that bend to hug the wall. The movement, achieved by LEGO Technic joints, allows the vehicle to adjust to the angle of the wall while also properly distributing the weight to prevent tipping. Watching it move across the wall feels almost organic, like a mechanical centipede on a stone.

The next wall is so tall that a complete rethink is needed. Brick Technology introduces the ladder vehicle, a creation that seems to break all the rules of LEGO. This machine uses a rotating ladder mechanism with rungs that catch the wall and pull the vehicle up. Powered by 2 motors the ladder spins continuously and the vehicle climbs like a firefighter up a building.

The challenge peaks with the propeller vehicle, an interesting move away from ground-based solutions. This machine uses spinning LEGO propellers to generate lift, pressing itself against the wall while climbing up. The propellers, along with a light frame, provide just enough upward thrust to counteract gravity.

Each vehicle improves on the preceding one, demonstrating a deliberate approach to issue solving. Brick Technology is a Finnish software engineer with a decade of experience, sources parts from BrickLink, a marketplace for LEGO parts, so he can get the specialized pieces he needs for these builds. No steering, a deliberate constraint, means he has to focus on mechanical innovation rather than navigational finesse. The video is set to Patrick Patrikios’ “The Awakening” and pairs the sound of LEGO with a pulsing soundtrack to make it ASMR-like.
