We’ve all played some variant of that simple old racing video game. It’s the one that involves swerving around cars in front without crashing, as the pace steadily increases further. [Dr. Engine] has recreated that very game in the physical world, with the help of LEGO Technic.
The design uses what appears to be a LEGO tank tread to create a treadmill for a LEGO car. The initial design is hand-cranked, but [Dr. Engine] soon upgrades this with a motor. The wide treadmill is then fitted with a steering wheel. This steers the car laterally along the treadmill via a simple pulley system. From there, it was a simple job of adding gearbox to change the speed of the treadmill, and obstacles for the car to dodge. Double-sided table affixed small die-cast cars to the track to fit the theme of the build.
It’s great fun watching the car buck and weave over the undulating track, and we’d certainly love to compete with friends for the high score. We’ve seen similar builds before, too, like this all-LEGO suspension dyno. Video after the break.
I like it!
Yep so do I. I know there are HaD readers who decry LEGO articles but I love the ingenuity shown on these contraptions. As an AFOL myself I’ve built logic gates, a binary encoder, torque amplifier and a stack of GBC’s. Not all worked as well as planned (could’t get an XOR gate figured out without a lot of complexity, and the amplifier didn’t work reliably at all) but I do say please keep these articles coming.
This is just 1 of the reasons that I love Hackaday.
Even if I don’t understand the subject, I either learn something, or it makes me happy.
Sometimes both!
Very neat!
It’s a lot like the early electromechanical arcade race games, which also had a belt (but not made of Technic), like Sega’s Drivemobile: https://sega.fandom.com/wiki/Drivemobile
I want that. It seems so cool😎
