Testing a Lego car against longer and longer gaps that it needs to drive over. Gradually improving the car until it becomes a capable gap crossing/bridging vehicle. Things you need to consider: wheel diameter, wheel count, 8WD, wheel position, center of mass, frame length, frame strength, moving mass, weight reduction. Enjoy!<br /><br />Base rules for all builds:<br /> -max length 1 meter<br /> -no steering (to simplify the builds)<br /> -only Lego parts used
