Abstract

Following a successful Mission Concept Review in April 2025, the LunarLeaper team is advancing the design of a ~15 kg legged robot for investigation of a lunar volcanic pit. The review established Level 0/1 requirements and a concept of operations, while highlighting key challenges in locomotion maturity (TRL 4), power and thermal margins, and dust mitigation. To address these challenges, we are conducting interconnected studies that include morphology analyses, learning-based locomotion control, actuator and thermal modeling, and simulations of regolith interaction. Together, these activities form a framework that links morphology, actuation, control, and environment to mission level feasibility. By exposing key sensitivities of a legged robot, they enable better-informed Level 2/3 requirements, provide the foundation for the upcoming System Requirements Review (SRR), and establish a path toward hardware designs in Phase B.
