Fastener Tools
Robotic Wrench / Driver Tools for Fastener Operations
Robotic wrench and driver tools are 2-kilogram end-effectors designed to install and remove bolts, screws, and other fasteners during lunar maintenance operations. Utilizing torque-controlled brushless direct-current drivers, force-torque sensors, and a 20-size socket library, these tools deliver between 1 and 100 Newton-meters of torque compliant with ISO 16156 standards while consuming 10 watts. Lunar deployment requires managing autonomous robotic tool changes across standard fastener interfaces and integrating automated drift compensation to maintain precise torque calibration over a 15-year design lifetime with a 20,000-hour mean time between failures.
