Mars Sojourner Rover 
Full Scale w/ radio control

The Rover (which is basically a robot that can drive around the planetary surface), was a vital part of the Pathfinder mission. Christened Sojourner, the little rover carried a variety of equipment to help analyze the Martian surface, including the APXS system. Its mission included analyzing rocks in a 10 meter circle around Pathfinder. The Rover's wheels were designed with steel treads and cleats to help it clear the rocky terrain. Its speed was not very impressive (only .6 meters per minute). To prevent the little rover from tipping over, it was equipped with motion sensors on its frame that analyzed tilt. The rover took many images of the surface, and the rocks that it had analyzed, sending them back to Earth along with scientific data. 

A previous try at the rover idea was made by the Russians in 1970. Called the Lunakhod 1, it was landed on the moon and took more than 20,000 images. 

The Sojourner rover was the first to actually be operated on another planet. The Rover's operations included taking images each sol to determine the operations for the next sol, to take and analyze soil samples, imaging the pathfinder lander to help with engineering assessment, and conducting a series of experiments to validate the rover idea. It's every move was tracked during its time on Mars, including images of every trench its wheels created, thermal monitoring, logging of vehicle performance data, and records of sensor performance. The mission was a guideline for future rover based missions and helped us better understand the Red Planet itself. risk to human explorers.
