Whole-body optical motion capture and force-plate recordings of 11 adults performing a simulated MMH sequence — floor lift, carry while walking, shelf placement and return of a 13.6 kg box — without an exoskeleton and wearing the Levitate Airframe (4.9 kg), Ekso Bionics EksoVest (6.7 kg) and SuitX ShoulderX (8.6 kg). Collected in 2024 to characterize how shoulder exoskeletons affect balance: phase-specific margin of stability, sample entropy of the body+load CoM, and CoP time-to-boundary during placement. Box tracked as a rigid body; OpenSim-compatible. Release planned.
