Exoskeleton. HULC

Lockheed Martin’s HULC is an un-tethered, battery powered, hydraulic-actuated anthropomorphic exoskeleton that provides users the ability to carry loads up to 200 pounds for up to 20 kilometers on a single battery charge over all terrains. HULC’s design allows for deep squats, crawls and upper-body lifting with minimal human exertion. An advanced onboard micro-computer ensures the exoskeleton moves in concert with the operator. HULC is an innovative solution that improves endurance and reduces the risk of injury to the soldier.

Lockheed Martin is a leading provider of advanced technology solutions for the warfighter, including wearable situational awareness, a broad range of mobility assistance systems and power management systems. Lockheed Martin is also exploring exoskeleton designs for industrial, medical and a wide variety of military mission specific applications.

Dismounted warfighters often carry heavy combat loads that increase the stress on the body leading to potential injuries. With a HULC exoskeleton, these heavy loads are transferred to the ground through powered titanium legs without loss of mobility.

The HULC is a completely un-tethered, hydraulic-powered anthropomorphic exoskeleton that provides users with the ability to carry loads of up to 200 pounds for extended periods of time and over all terrains. Its flexible design allows for deep squats, crawls and upper-body lifting.

An onboard micro-computer ensures the exoskeleton moves in concert with the individual. The HULC’s modularity allows for major components to be swapped out in the field. Additionally, its unique power-saving design allows the user to operate on battery power for extended missions. When battery power is low, the HULC system continues to support the loads and does not restrict mobility. HULC can also support a maximum load, with or without power.

Lockheed Martin is also exploring exoskeleton designs for industrial use and a wider variety of military mission specific applications.

In July 2013, for seven weeks, U.S. Army warfighters will be evaluated to assess the effects of load carriage with and without use of the HULC exoskeleton. Biomechanical testing will measure changes in energy expended by users, assessing how quickly individuals acclimate to the system and whether there is a reduction in metabolic cost. Testing will also determine if there is an improvement in metabolic efficiency as measured by oxygen consumption per unit total mass, when wearing the ruggedized HULC as compared to not wearing the device under identical load, speed, grade and duration conditions.

HULC® with Lift Assist Device
Exoskeletons Provide Performance Enhancement for Sustainment Capabilities

Military logistics and sustainment missions often require personnel to repetitively lift and carry heavy loads for several hours a day. These activities significantly increase muscular-skeletal stress on the body, potentially leading to injuries. HULC is a lower-body, electro-hydraulicallypowered exoskeleton designed to lift and carry heavy loads. It transfers weight through the machine’s frame to the ground, significantly reducing operator fatigue and exposure to injury. Additionally, HULC’s selfcontained power supply eliminates external power cords or hydraulic lines that restrict deployment.

The HULC Lift Assist Device allows single operators to safely lift heavy loads that currently require two or more people. The Lift Assist Device, easily mounted on the back of the HULC exoskeleton, maintains users’ normal lifting and motion range. This lightweight, power-assisted device has multiple end-effectors that are quickly and easily exchanged to enable lifting and carriage of various boxes, containers and munitions.The device’s counter-balance weight keeps the center of gravity close to the operator to maintain balance and positive control. Using gripping and winch sensors, an onboard micro-computer ensures the exoskeleton moves in concert with the individual to maintain balance and accurate object placement. Lockheed Martin continues to research and develop exoskeleton capabilities, including more efficient power systems and additional designs for industrial use and a wide range of mission specific applications.

Exoskeleton. Suit HAL

Robot Suit HAL (Hybrid Assistive Limb®)  is a cyborg-type robot that can supplement, expand or improve physical capability. This exoskeleton, or external skeleton, not only protects its wearer but gives him or her tenfold strength.Developed by ccientists at the University of Tsukuba and Cyberdyne Inc.  in the New Energy and Industrial Technology Development Organization‘s (NEDO) unmanned anti-disaster system research and development project. NEDO, Japan’s largest public R&D management organization, introduced its latest disaster. Receives its global safety certificate (ISO / DIS 13482) in Japan on February 25, 2013.

When a person attempts to move, nerve signals are sent from the brain to the muscles via motoneurons, moving the musculoskeletal system as a consequence. At this moment, very weak biosignals can be detected on the surface of the skin. “HAL” catches these signals through a sensor attached on the skin of the wearer. Based on the signals obtained, the power unit is controlled to move the joint in unison with the wearer’s muscle movement, enabling HAL to support the wearer’s daily activities.

This is what we call a ‘voluntary control system’ that provides movement interpreting the wearer’s intention from the biosignals in advance of the actual movement. Not only a ‘voluntary control system’ “HAL” has, but also a ‘robotic autonomous control system’ that provides human-like movement based on a robotic system which integrally work together with the ‘autonomous control system’. “HAL” is the world’s first cyborg-type robot controlled by this unique Hybrid System.

To February 2013, Cyberdyne, has so far leased some 330 suits to 150 hospitals, welfare and other facilities in Japan since 2010, at 178,000 yen ($1,950) per suit per year.

sse

“HAL” is expected to be applied in various fields such as rehabilitation support and physical training support in medical field, ADL support for disabled people, heavy labour support at factories, and rescue support at disaster sites, as well as in the entertainment field.
