Passive Load-Bearing Exoskeleton





Mawashi's Ultralight Passive Ruggedized Integrated Soldier Exoskeleton (UPRISE®), initially developed for Special Operations Forces (SOF), is a wearable device that redirects the load carried by the soldier to the ground. This Passive Exoskeleton developed by Mawashi is a disruptive technology that has the potential to change the way wars are fought by deeply transforming soldier systems, soldier modernization programs and load carriage domains.

Actually, lessening the soldier's burden is one of the top priorities of Armed Forces across the world. For a soldier equipped with the UPRISE® Passive Exoskeleton, it would be easier to transport its equipment (up to 120lb depending on missions) and its ease and range of motion would not be hampered by the carried weight as it is the case without the exoskeleton on. This will guarantee him dominance and efficiency on the battlefield while being equipped with all the tools and features required by its mission.

The need

Activities involving load transport are one of the major causes of musculoskeletal injuries for soldiers. When carried on long distances, the weight coming from soldier's equipment, backpack and ballistic plates can cause various injuries that affects at different level the efficiency of the soldier. In addition, heavy loads entail a metabolic expenditure (energetic cost of locomotion) increase for the dismounted soldier, which in turn causes a premature exhaustion. Increase in soldier fatigue has been proven to reduce cognitive functions (reduced efficiency of the soldier in hostile environment) and to raise the risk of injuries, therefore load carriage is responsible for several lesions amongst the military population.

Most common injuries pertaining to load carriage generally affect the legs joints, the musculoskeletal system and the skin. Notably, blisters, lower back pain, metatarsalgia, bone fractures, knee pain and rucksack palsy were observed on many soldiers following intense load carriage sessions.

The UPRISE® Tactical Exoskeleton fulfils this imperative need to increase soldiers' protection against injuries that strongly hamper their capacity in theater of operation.

Wars taking place more and more in urban environments, soldiers will in a near future have to raise the frequency and duration of their pedestrian displacements, the targeted regions being hard or even impossible to reach with a vehicle.


Mawashi's solution

The UPRISE® Passive Exoskeleton is a complex structure made of high strength titanium that is perfectly adapted to the human body. Through its innovative and ultralight design, this exoskeleton achieve an unparalleled level of freedom of movement. In fact, with a minimal degree of resistance to movement, the UPRISE® Tactical Exoskeleton allows for all the movements involved during tactical maneuvers as well as other tasks required by dismounted soldiers and SOF operators. Its ruggedized and unique frame transfers from 50% to 80% of the load carried by warfighter's shoulders down to the ground.

The Patented UPRISE® Passive Exoskeleton consists of:

  • Flexible spine based on the human anatomy

  • Sliding belt for waist rotational degree of freedom

  • Fully articulated and ergonomic legs

  • Helmet support system



The key features of the UPRISE® Passive Exoskeleton are:

  • Provides load transfer capacity in static and dynamic conditions

  • Reduces musculoskeletal stress when soldiers carry heavy body-borne loads

  • Reduces discomfort related to carriage of heavy body-borne loads

  • Provides a high degree of kinematic compatibility with the user

  • Does not alter significantly physiological parameters during gait

  • Does not alter significantly the soldier's strategies during execution of primary and secondary operational tasks


Potential benefits of the UPRISE® Tactical Exoskeleton for the warfighter include:

  • Increased Performance

  • Increased Endurance

  • Increased Situational Awareness

  • Increased Combat Effectiveness

  • Decreased Musculoskeletal Injuries

  • Decreased Metabolic Expenditure

  • Decreased Fatigue

  • Decreased Discomfort


POTENTIAL Benefits for the Armed Forces

Potential direct and indirect benefits for Armed Forces related to the use of the UPRISE® Tactical Exoskeleton include:

  • Ensured Superiority & Dominance on the modern battlefield

  • Technological Advantage over near-peer competitors and threats against national interests

  • Enhanced Operational Readiness

  • Decreased Medical Costs

  • Decreased Rehabilitation Costs

  • Decreased Deployment Costs
