LEGO Experimental Vehicle vs Obstacle One build. One obstacle. A real mechanical test. This experimental LEGO vehicle goes head-to-head with an obstacle to see how traction, torque, and geometry perform under load. No ideal conditions — just real contact, resistance, and mechanical limits. #LEGO #Engineering #Mechanical #Satisfying #OddlySatisfying #STEM #Motion #ObstacleChallenge #LEGOTechnic #ExperimentalVehicles | Dr. Engine
