Designing a Lego Car to Cross Gaps

posted by Jason Kottke   Dec 02, 2021

In the second video by Brick Experiment Channel I’ve posted here in the past week, a Lego car is repeatedly adapted to cross larger and larger gaps, until it can cross a massive gap just a little narrower than the length of the car. As I said before about their climbing car video, watching the iterative process of improving a simple car performing an increasingly difficult task using familiar design objects is such an accessible way to observe how the process of engineering works.

One of the things you get to witness is when a particular design tactic dead ends, i.e. when something that worked across a shorter gap is completely ineffective crossing a wider distance. No amount of tinkering with that same design will make it work…you have to find a whole new way to do it.
