The document describes a team's proposal for an autonomous robot named "Digger" designed to explore Mars and dig holes. The team is composed of 5 students from engineering schools in Tunisia. The robot would be equipped with 6 independently powered wheels and a drill made of titanium to anchor it while digging. It would use a microcontroller and sensors to detect frequencies to guide navigation and avoid obstacles while digging on Mars. The team developed a 3D design for mechanical improvements using Solidworks software.
