Making a LEGO car cross longer and longer gaps

Watch more with these video collections:

Good engineering is created from a series of designs, tests, failures, and revisions to the design, all with the goal of solving a specific problem. This LEGO car video is a great example.

A follow up to their LEGO car vs obstacles videos, the Brick Experiment Channel tested their LEGO car “against longer and longer gaps,” making design improvements to the LEGO car so that it could cross the distances without a bridge.

“Things you need to consider: wheel diameter, wheel count, 8WD, wheel position, center of mass, frame length, frame strength, moving mass, weight reduction… Base rules for all builds:
-max length 1 meter
-no steering (to simplify the builds)
-only Lego parts used”
