3. INTRODUCTION
 The Human Universal Load Carrier (HULC) is an
exoskeleton being developed by Lockheed
Martin for dismounted soldiers.
 The hydraulically-powered HULC enables
soldiers to carry heavy loads with minimal
strain on their body.

5. DEVELOPMENT
 The HULC underwent laboratory testing in October 2010, after
Lockheed Martin upgraded the ruggedised system for flexibility and
suitability to a variety of users.
 The system was put through biomechanical, dynamic load and
environmental testing.
 Treadmill testing measured the decrease in metabolic cost of the
user.
 The system's sustainability in various environmental conditions was
evaluated through sand, wind, rain, temperature and humidity
testing.
 The HULC's tests at the Natick Soldier Center began in June 2011.

7. DESIGN
 It is un-tethered and flexible enough to allow for
squatting, crawling and upper-body lifting of the user.
 The system weighs 53lb (24kg) without batteries. The
design is adjustable to suit users with a height of 5'4" to
6'2".
 The exoskeleton doesn't require any external control
mechanism as it is controlled by a micro-computer
installed within the system.
 The computer enables the HULC to sense the user's
requirement and adapt to the situation accordingly.

9. FEATURES
 The HULC has a range of 20km when the warfighter moves on level
terrain at 4km/hour.
 It supports front and back payloads.
 The user can move at maximum speed of 11kmph long duration
and at 16kmph burst speed.
 The system has various mission-specific attachments and can carry
integrated systems such as armour, heating or cooling systems, plus
sensors.

11. POWER SUPPLY
 The HULC exoskeleton operates on lithium polymer
batteries. The power-saving feature enables the system
to support maximum load even when the battery power
is low.
 In January 2010, Lockheed Martin contracted Protonex
Technology to develop fuel cell power supply system for
the HULC to support extended missions of 72 hours.
 The HULC with rechargeable power supply enables the
soldiers to carry fewer batteries during extended
missions.
