1 Decreasing Musculoskeletal Injuries in Soldiers in Soldiers Through the Use of Anthromorphic Exoskeletons

2 Combat Loads The average load for a soldier currently deployed to Afghanistan is 91lbs This includes a soldier’s Rifle Ammunition Rations Spare Boots/socks Sleeping Gear Shovel Kevlar plates Medical kits called (IFACS) NVG’s (mission dependant) Radio’s Gunner’s/Mortar men's munitions distributed evenly amongst the squad And a multitude of other devices depending on the scale and importance of the mission at hand On average an infantry soldier in Afghanistan will march no less than 40 km if no mounted vehicles or birds are available for transportation for a mission of relative importance

3 Back injuries from heavy loads Terrain in Afghanistan makes carrying even the lightest of loads difficult and physically draining even for physically fit soldiers In extreme cases mortar men can have loads that reach up to 140lbs Only 2% of the soldiers who received treatment for musculoskeletal injuries (primarily in their back) and were treated at hospitals in either Germany or Washington returned to their deployments The Bottom Line: Today’s Army cannot afford to lose soldiers due to injuries that are easily preventable

4 The HULC: (Human Universal Load Carrier) Designed by Berkeley Robotics and Human Engineering Lab (BRHE) – An anthromorphic, completely untethered, hydraulic powered exoskeleton that allows the operator to carry up to 200 lbs at a time. Specifications: Weight: 53lbs (without batteries) Power: lithium polymer batteries Electronics: flexible, expandable electronics architecture. Custom single-board micro electronics housed in a sealed enclosure. Heat sinks on actuators Hydraulics: Efficient low-flow, high pressure hydraulic system that utilizes standard hydraulic fluid

5 Features: Range: 20km on level terrain at 4 km/hr Load Carriage: Up to 200 lbs; carries front and back loads Speed: 3mph march; up to 10 mph burst Fits soldiers from 5’4”-6’2” Extensibility: Wide variety of mission specific attachments Capable as serving as a backbone for integrated systems such as armor, heating or cooling systems, sensors and other custom attachments Long-range extended 72 hour mission

6 Functionality Distributes the weight load through the frame of the exoskeleton distributes it to the ground Can still support weight if the batteries are low or depleted, which allows the operator the safety of not being crushed under the weight of the load if a malfunction occurs Easy to put on: a soldier only needs to put his boots into the foot bed and strap the straps at his knee waist and shoulders and the HULC is fully operational Uses sensors in the foot to interpret the movement of the soldier, sends those signals to the microprocessor housed in the electronics compartment, which then sends signals to the hydraulic system of the HULC in order to replicate the soldiers movements. Normal batteries can supply a soldier with enough power for a 48 hour mission, and other versions are available that can increase the operational time to 72 hours. In the future it is the hopes of both Lockheed Martin and the Berkeley Robotics and Human Engineering lab to create an exoskeleton that provides the soldier with 360 degree armor, protecting him from small arms fire
