Locking Tray Assembly
Rotary mechanical locking head attaches and releases the storage unit — a passive interface with no powered actuation at the payload, verified to FoS ≈ 4.

Motorized Cart Elevator
Standalone cart raises the storage unit to the handoff height — offloading lift duty from the gantry to cut structural load and improve operator safety.
