  1. Hybrid assistive limb Chad Fair

  2. What is it? • 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

  3. Who Developed it? Why? • 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

  4. How does it work? • Voluntary control system • When a person attempts to move, nerve signals are sent from the brain to the muscles from the motoneuronsand 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.

  5. How does it work? (Cont.) • 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

  6. Results • 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

  7. Problems • 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

  8. The Future of HAL • 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
