IntroductionThe Hybrid Assistive Limb (also known as HAL) is a powered exoskeleton suit developed by Japan's Tsukuba University and the robotics company Cyberdyne. It has been designed to support and expand the physical capabilities of its users, particularly people with physical disabilities. There are two primary versions of the system: HAL 3, which only provides leg function, and HAL 5, which is a full-body exoskeleton for the arms, legs, and torso.In 2011, Cyberdyne and Tsukuba University jointly announced that hospital trials of the full HAL suit would begin in 2012, with tests to continue until 2014 or 2015. By October 2012, HAL suits were in use by 130 different medical institutions across Japan. In February 2013, the HAL system became the first powered exoskeleton to receive global safety certification. In August 2013, HAL received EC certification for clinical use in Europe as the world's first non-surgical medical treatment robot. In addition to its medical applications, the HAL exoskeleton has been used in construction and disaster response work.

HistoryThe first HAL prototype was proposed by Yoshiyuki Sankai, a professor at Tsukuba University. Fascinated with robots since he was in the third grade, Sankai had striven to make a robotic suit in order “to support humans.” In 1989, after receiving his Ph.D. in robotics, he began the development of HAL. Sankai spent three years, from 1990 to 1993, mapping out the neurons that govern leg movement. It took him and his team an additional four years to make a prototype of the hardware.

The third HAL prototype, developed in the early 2000s, was attached to a computer. Its battery alone weighed nearly 22 kilograms (49 lb) and required two helpers to put on, making it very impractical. By contrast, later HAL-5 model weighs only 10 kilograms (22 lb) and has its battery and control computer strapped around the waist of the wearer.

Activities of Daily Living

When a person attempts to move their body, nerve signals are sent from the brain to the muscles through the motor neurons, moving the musculoskeletal system. When this happens, small bio signals can be detected on the surface of the skin. The HAL suit registers these signals through a sensor attached to the skin of the wearer. Based on the signals obtained, the power unit moves the joint to support and amplify the wearer's motion. The HAL suit possesses a cybernic control system consisting of both a user-activated “voluntary control system" known as Cyberia Voluntary Control (CVC) and a “robotic autonomous control system" known as Cybernic Autonomous Control (CAC) for automatic motion support.

Design and mechanics:

Japan’s robot suit venture Cyberdyne president and Tsukuba University’s Yoshiyuki Sanai, a professor, have displayed the full-body HAL – Hybrid Assistive Limb – robotic exoskeleton. This learns the user’s motion or gait and assists the wearer’s movement, said Prof. Sanai. He said they have spent quite a few years developing HAL-5, the awesome robot suit that can make paralyzed people walk. Its maker, Japan-based robot venture Cyberdyne, is now introducing a new version that is designed for people who suffer from muscle diseases and are in danger of losing their ability to walk.

Robot suit offers glimmer of hope to the paralyzed: The “conventional” HAL-5 robot suit helps

paralyzed persons walk (and lift heavy objects) by transforming brain signals sensed through the skin into motion. Cyberdyne has now modified the suit so that it can detect signals coming from extremely weak muscles, too. According to a report in Japan’s biggest business daily The Nikkei, Cyberdyne plans to start clinical trials of the new robot suit in 2012. The studies will last until 2014 or 2015, with the company hoping it will slow down or even stop the diseases the wearers suffer from.

A health ministry panel on Nov. 10 for the first time approved a wearable, robotic suit for designation as a medical device to help patients with intractable diseases regain their walking abilities.The Ministry of Health, Labor and Welfare is expected to officially certify the lower limb type “Robot Suit HAL” as a medical device by the end of this month. Consideration will be given on whether health insurance will cover treatments using the device.

Cyberdyne Inc., a start-up in Tsukuba, Ibaraki Prefecture, developed and manufactured the motorized robot suit. It is higher in performance than the company’s nonmedical version that focused mainly on providing support for people with difficulties in walking.

In the medical version, sensors attached to a patient’s thighs and knees detect electric signals generated when the patient tries to move his or her muscles. The built-in computers then operate motors at the patient’s joints to assist in walking without the support of medical staff.The device makes the patients feel capable of walking on their own, which sends positive stimulus to the brain and helps them regain their ability to walk, a Cyberdyne official said.

Medical device to help patients walk:

How, and where, can HAL be used?

Hospital and nursing homes: Can aid severely disabled people,injured,elderly or those in rehabilitation.

Handling and work sites: Aid in the drudgery of heavy labour workers(such as on a construction site) who lift heavy loads.

Emergency: Could aid rescue support workers at disaster sites when they need to lift heavy loads.

Military: Some have speculated its potential use in the military as an aid to increase endurance, speed, and strength, particularly those of the wounded.
