We’ve all played some variation of the plain old racing video game. It’s about swerving around cars in front without crashing, as the pace keeps increasing even further. [Dr. Engine] has recreated that very game in the physical world, using LEGO Technic.
The design uses what appears to be a LEGO tank step to create a treadmill for a LEGO car. The original design is hand cranked, but [Dr. Engine] will soon upgrade this with a motor. The wide treadmill is then equipped with a steering wheel. This steers the car laterally along the treadmill via a simple pulley system. From there it was a simple job to add a gearbox to change the speed of the treadmill, and obstacles for the car to avoid. Double-sided table attached small die-cast cars to the track to match the theme of the building.
It’s a lot of fun to watch the car goof and weave across the undulating track and we’d certainly like to compete with friends for the high score. We’ve seen similar builds before, like this all-LEGO suspension dyno. Video after break.
