After impressing us with a LEGO car that can climb over a stack of books, the Brick Experiment Channel is back with a simpler vehicle design challenge. The plan? Dial in the right mix of traction, gearing, wheelbase, and weight balance to climb the steepest sheet of glass possible. And then, start cheating.
If you slap wheels onto a basic motorized LEGO vehicle, it will have a hard time climbing over obstacles. The Brick Experiment Channel tested out a variety of design and drivetrain modifications to their car to see what it would take to climb over stacks of books with the best results.
We always assumed that LEGO constructions were fairly delicate, and certainly not capable of lifting more weight than we can. But the Brick Experiment Channel shows off a contraption they built that can lift 102.2 kg, or about 224.8 lb, using only LEGO Technic parts and string.
