Modeled after NASA's Mars 2020 Mission Perseverance Rover, this design features two different versions that show two different ways of driving with six wheels while steering with four wheels.

​

Both versions also feature spring (rubber) suspension to improve traction over bumps, a folding extendable arm with the color sensor at the end, and the distance sensor mounted on top of the mast.

Choose either the 4-Wheel Steering or Zero Turn version to start with, then build the sub-assemblies that it uses.
