People often suffer from various disorders related to their physical health, which also include disorders of the nervous, vascular and integumentary systems, muscular and neurologic diseases. Consequently, these violations probably affect the musculoskeletal system and complicate the daily lives of these people. However, with the daily development of science and technology, doctors and inventors are trying to create some kind of device that can make life easier for people with such disabilities. To date, some examples of these developments are already invented. One of these developments is a powered exoskeleton Hybrid Assistive Limb (HAL-5). Hybrid Assistive Limb (HAL) is a full-body suit, which was designed to help people with degenerated muscles or spinal injuries or brain disorders. Now we are going to describe appearance, functions and main characteristics of this robotic device.
2. Data and producers.
The wearable-type robot “Robot Suit HAL” was created in Japan, notably by Cyberdyne, Inc. This company was founded in 2004 to exploit the work of a group of cybernetics researchers headed by Yoshiyuki Sankai, a Professor of System and Information Engineering at Tsukuba University.  The study about Hybrid Assistive Limb was started by professor Sankai in 1992 and lasted until 1996. The result of this hard work was HAL-1 (fig. 1), first prototype of HAL series robots. The next robot which was built with cardinally other design is HAL-3 (fig. 2). It was invented in 1999 and had been used for 6 years. Final version of HAL robot, HAL-5 (fig. 3), was discovered in 2005 and still is being developed by professor Yoshiyuki Sankai in his laboratory at University of Tsukuba. Cyberdyne Inc. has been manufacturing and is currently distributing of the HAL-5 to the residences of Japan and Europe.
