Mars Rover

I show you now a 3-day effort, the best I have designed so far, which is: this vehicle that simulates the rest of the vehicles on Mars, given that the place the vehicle is traveling on is the land of Mars with some barriers, the vehicle has 6 driving wheels and the wheels are connected to springs, choice The force of the spring depends on the weight of the vehicle "under the influence of the gravitational acceleration of Mars, which is equal to 3.721 m/s²" in order to maintain the stability of the vehicle.
