The obstacle reconfiguration

Brick Experiment Channel demonstrates a robotic climber:

Testing a Lego car against different obstacles and improving it until it becomes a capable climber. Demonstrates what you need to consider: wheel diameter, gear ratio, 4-wheel drive, tire grip, breakover angle, weight distribution.

Quite the climber!
