With the Off-road Rovers kit, learn about belt drives and tank treads and engineer awesome motorised models that can drive over rough terrain.

Riding a bike on a smooth road surface is much more fun than riding on a sandy path. On the sand, the tires sink in and get stuck. The same is true of any type of vehicle with wheels. 

Tracked vehicles are much more complicated than normal vehicles. Tracked vehicles have wheels that roll along two tracks that turn in an endless loop. This spreads the weight of the vehicle over a larger surface area, so it does not sink into the ground.
