Quick-Change Tool Coupler

Standardised Quick-Change Tool Coupler

The standardised quick-change tool coupler is a 2 kg stainless steel interface mounted to the L3-ROB-MANIP-ARM manipulator arm, enabling autonomous end-effector swaps in one second without operator intervention. Drawing zero watts while supporting a 25 kg coupling load, the unit integrates a mechanical lock, electrical contacts, and fluid quick-disconnects. Surviving the lunar surface across a 15-year lifetime and a 50,000-hour mean time between failures requires a sealed mechanical lock design, preventing abrasive lunar regolith and hard vacuum from degrading exposed contacts or jamming precision robotic mating operations.
