Outline Project overview Block diagram Design challenges Individual contributions Project demonstration Questions / discussion

Project Overview The goal of this project is to design and build a miniature replica of the Curiosity, a Mars Science Exploration Lab. The rover is battery powered and is controlled through a wireless router via the base station. The rover will ultimately be part of an exhibit in Science Central, a children’s museum in Fort Wayne, Indiana.
