Hybrid assistive limb

Chad Fair



Cyborg-type robot that can support, expand or
improve physical capability.
Capable of allowing the operator to lift and carry
about five times as much weight as he or she could
lift and carry unaided
Two Versions
HAL 3 – Legs only
 HAL 5 – Full body suit




Researched started by Dr. Sankai, a professor at
Tsukuba University in Japan.
HAL was created for rehabilitation patients and
physical training support in medical field.
Can also be used for heavy labor, and possible
rescue support at disaster sites,

Possibly in the entertainment field in the future.

Not intended for Military Use

Voluntary control system

When a person attempts to move, nerve signals are sent
from the brain to the muscles from the motoneurons and
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 user.

Based on the signals obtained, the power unit is
controlled to move the suit in unison with the user's
muscle movement.

Robotic autonomous control system


provides human-like movement based on a robotic
system which works together with the autonomous
control system
HAL is the world's first
cyborg-type robot
controlled by a hybrid system

voluntary control system mixed with
a robotic autonomous control system

Very Successful
By October 2012, over 300 HAL suits were in use by 130
medical facilities in Japan
In late February 2013, HAL received a global safety
certificate, becoming the first powered exoskeleton to do so
In November 2011, HAL was selected to be used for cleanup
work at the site of the Fukushima nuclear accident.
Increases patients stride length and walking speed
significantly

Only available in Japan at the moment

Expensive to the public



$14,000-19,000 for one suit
Decreases physiological cost Index after a
patient uses HAL
Very Short Battery Life

Needs to be continuously charged

Suit with…




Longer Battery Life
Less weight
Less expensive to public
Give more support to the user
Therapeutic games using the HAL that can
stimulate cognitive activities and help disabled
patients walk while playing.
Cyberdyne plans on modifying suits specifically
for disaster recovery like the Fukushima nuclear
accident
