The latest project in a longstanding correspondence between NOAO Tucson and the CADIAS center in La Serena, Chile focuses on Mars and Mars exploration. The objective was to provide a user-friendly yet moderately versatile imitation of the Spirit and Opportunity MARS rovers to be used by grade school students. In addition to basic motion, the rover that was built is able to take color photographs from a rotating camera, and avoid harmful collisions or structural stress via 'bumper' sensors on each of the wheels. The rover is intended to be used remotely via the Internet, and controlled locally via wireless radio. The focus of the project was to create a system that is stable, versatile, and user friendly. The majority of the system was coded in Java, including the micro controller, providing stability and a reliable internet protocol. A partial implementation of Scheme was used as a scripting language, providing an abstraction in the means of communication and control of the robot and allowing for a level of versatility in the range of commands available to the rover and the ease of tweaking those commands. A graphical user interface was implemented to provide a safe means of controlling the rover, creating an 'action queue' of safe commands to be sent as a block to the rover. We hope the project will provide a useful education tool for students in Chile, and potentially in the future students in Tucson as well.
