Hello, Houston? We have a problem. It is zero minus one hour and counting, and we have developed a malfunction with our Mars rover vehicle. Can you ship in a replacement soonest?
Levels of difficulty:
Level 1 - Build a simple model of a Mars rover vehicle Level 2 - As level 1, with a motor, which will cross the landscape of Mars Level 3 - As level 2, which will steer round in a circle
Equipment: KNEX set, plus a battery motor for level 2.
Test area: For level 2, a rough piece of ground, or a floor area with small objects on it, to test the vehicles ability to climb over obstacles.
Approach: What shape will your Mars rover be? How many wheels will it have? How will the wheels be fastened to the body? For level 2, how can you make the motor drive the wheels? Will the rover travel over rough ground like that found on Mars? For level 3, how can you make the Mars rover steer around in a circle?
