"Autonomous robot rovers will seek out samples and return them to a designated point in a set time period. Samples will be randomly placed throughout the roving area. They may be placed close to obstacles, both movable and immovable. Robots will be required to navigate over unknown terrain, around obstacles, and in varied lighting conditions to identify, retrieve, and return these samples. Winners will be determined based on the number of samples returned to the designated collection point as well as the value assigned to the samples."
