How can you fix a car that won’t climb? There are a lot of engineering solutions to consider, especially when you’re working with an easy-to-modify vehicle like a LEGO car.
This Brick Experiment Channel video shares how they make a LEGO car climb 9 increasingly difficult obstacles with changes to wheel diameters, gear ratios, the drivetrain, tire grip, breakover angle, and weight distribution.
Can they make a versatile climbing vehicle with four wheels, no steering, and only LEGO parts? Watch as they put each version of the vehicle to the test across 15 experiments in total. A gamepad helps with controlling specific parts of the vehicle at specific times.
The second video picks up where the first leaves off. With the addition of a second adjustable joint, the vehicle continues to persevere through obstacle 9 and beyond… though it does take some practice.
