3 Rover Chassis Designs
Rover are robots that are free to move around its environment by spinning its wheels or something similar to wheels. How many wheels and in what arrangement are design decisions that can have a major effect on how the rover moves. How the rover contacts the ground will determine friction and traction, allowing or preventing it from moving.
