Abstract:
A robot mining system was designed to traverse the Martian chaotic terrain, excavate a minimum of 10 kg of Martian regolith and deposit the regolith into a collector bin within 10 minutes as part of the competition. A systems engineering approach was employed to conduct this design project. The designed mining robot consisted of two major components: (1) mechanical system and (2) control system. In this paper, design, prototyping, and assessment of the mechanical system are demonstrated. The final mining robot consists of an aluminum frame driven by four motors and wheels, and a scoop and lifting arm subsystem for collecting and depositing Martian regolith, which was powered by two computers and used two commercially-of-the-shelf sensors to navigate the Martian terrain. Engineering students and faculty from different engineering disciplines collaboratively participated in this effort. This design project provides a multidisciplinary environment for the students to explore and development their skills in designing, problem formulating and solving, teamwork, communication, project management, and outreach.
