Level 2 · hardware
Repair Robot Fleet
Heavy Repair Robot Fleet
Mobile manipulator platforms with tool-carrying capability for repair operations
Purpose
Execute physical repair tasks including component replacement, welding, and fastening
Context
Component of L1-ROB within the Lunar Ark system
Principles
- ▸Heavy-duty mobile manipulators combine mobility with dexterous manipulation
- ▸Teleoperation fallback allows Earth-based control for complex repairs
- ▸Modular tool attachments enable diverse repair tasks with single platform
- ▸Cooperative manipulation using multiple robots handles large components
Typical implementations
- ▸NASA Robonaut 2 (dexterous humanoid robot, ISS tested)
- ▸DARPA ARM program autonomous robotic manipulation
- ▸Mining industry autonomous repair systems
- ▸Nuclear industry remote handling and repair systems (ITER tokamak)
Lunar considerations
- ▸Must handle repairs in both pressurized interior and vacuum exterior
- ▸Dust contamination during exterior repair operations must be managed
- ▸Heavy component handling in 1/6g requires different force control than Earth
- ▸Repair capability must evolve as Ark systems age and new failure modes emerge
