The University of Houston–Clear Lake (UHCL) Lunabotics team developed an autonomous robot capable of excavating lunar regolith and constructing berms for the 2025 NASA Lunabotics Challenge. This paper describes the design methodology, systems engineering process, and trade studies that guided development. Key innovations include a conveyor-based excavation system, a tracked differential drive for terrain mobility, and autonomous navigation using LiDAR and IMU. Emphasis was placed on reliability, modularity, and dust protection. The resulting system met major competition goals and offers a foundation for future lunar robotics initiatives.
