Bionic suit final
This document summarizes various exoskeleton technologies. It discusses how exoskeletons can assist those with disabilities by boosting strength and allowing paralyzed individuals to walk. Exoskeletons can also enhance human abilities for military and rescue purposes. Key components of exoskeletons include a skeleton structure, microcomputers, power sources, and control interfaces. Several existing exoskeleton models are described, along with their applications in medical, military, rescue, and entertainment fields. Challenges to further development include improving power sources and making exoskeletons smaller and more affordable. The future potential of exoskeletons is seen as helping both civilians and soldiers.

- 2. INTRODUCTION A powered exoskeletonis a mobile machine consisting primarily of an outer framework worn by a person, and powered by a system of motors or hydraulics that delivers at least part of the energy for limb movement.
- 3.
- 4. WHAT IS THENEED OF AN EXOSKELETON? • It is a suit which assists the wearer by boosting their strength and endurance. So it is used by paralyzed patients for walking. • It also gives the wearer superhuman powers. So it can also be used in military and rescue fields.
- 5. Main Parts • Skeleton •Micro Computers • Power supply • Wrist band or control pad • Power Gloves(only in some)
- 6. SKELETON •It may bemade of any light weight metals like aluminium, nickel, titanium and hard plastics. •The potential of using Carbon fibre is under research.
- 7. MICROCOMPUTERS • Microcomputers controlthe movements of various motors or hydraulic cylinders associated with the joints. • It sends signals to various joints as per the required mode.
- 8. POWER SUPPLY • Thesecan be powered by an internal combustion engine, batteries or potentially fuel cells. • Regenerative methods like using piezoelectric shoes or power producing pendulums as in the case of kinetic watches will increase the power backup. • Wireless charging will make a giant leap in the future of exoskeletons.
- 9. Wrist Band [Controlpad] • The user selects various modes by pressing the buttons on the wrist band. • Various modes are sit to stand, walk forward, turn, …
- 10. POWER GLOVE • Thefingertips in the Glove are equipped with force-sensitive sensors that recognize when the user grasps an object. • A microcontroller calculates how much force should be added and controls small engines that in turn move artificial tendons connected to the fingertips of the glove.
- 11. •Ekso suit isused by paralyzed patients for walking. •Users can stand, walk & even climb stairs. •It is powered by 4 motors one at each hip & knee joint that are controlled by micro computers. WORKING OF EKSO
- 12. WORKING OF EKSO •Users can balance using crutches. • Users select different modes from the wrist band. • It also uses motion sensors to study the walking style of users. • It weighs 23kg & users can walk at a speed of 3.2 km/hr. • Newer versions of ekso suits have power backup up to 6 hours.
- 13. COMPLICATIONS FACED • Powersupply • Skeleton material • Actuators • Joint flexibility • Speed of response • Detection of unsafe or invalid motions • Pinching • User size • Cost
- 14. USES • Military • Medical •Rescue • Entertainment
- 15. MILITARY USES • Protectssoldiers from enemy fire by repelling bullets. • Increases the efficiency of soldiers. • By further advancements it may even be able to carry a wounded soldier back to base. • Soldiers can carry up to 90kg at a speed of 7mph for long time and has a burst speed of 10mph. • Its load carrying capacity works even without power. • It can be used for mission in places where vehicles can’t go.
- 16. MEDICAL USES • Helpsparalytic to stand, walk and even climb stairs. • People with muscular dystrophy and other neuromuscular disabilities could use the exoskeleton to amplify their muscle strength. • Also used for physical therapy. • Can be used in surgery for very precise movement with the doctor controlling it remotely.
- 17. RESCUE • It canbe used by firemen to go into risky and hazardous environments for rescue operations. • It can be used to rescue people from the remains of destroyed buildings in an earthquake.
- 18. ENTERTAINMENT • These suitscan be used to perform superhuman stunts without risking human lives. • It can also be used as a preventive measure in extreme sports like sky diving, para gliding …
- 19.
- 20. LIFE SUIT • MontyReed, a former Army Ranger who was paralyzed after a night parachute jump developed Life suit. • The Lifesuit is intended to allow passive movements to the legs.
- 21. REX • It weighs84 pounds. • Stabilizes the body leaving hands free. • Developed by eksobionics. • Differs from Ekso suit or Rewalk in the sense that Rex is self balancing.
- 22. HAL 5 • HybridAssistive Limb • The HAL suit works by detecting signals sent from the brain to muscles and amplifies them. • It is made of nickel and aluminum alloys, along with a thick plastic casing.
- 23. BLEEX • Berkeley Lower ExtremityEXoskeleton. • It combines human control system with robotic muscle. • More than 40 sensors monitor the movements & relay them to an onboard computer.
- 24. TROJAN • It isthe first ballistic proof exoskeleton. • It has so far been able to stop bullets, knives, clubs and light explosives. • The Trojan has an intake fan and an exhaust fan in the helmet to keep the soldier from becoming overheated. • High impact plastic is used to create this 40 pound protective exoskeleton.
- 25. HULC • Human UniversalLoad Carrier. • Meant for military use. • Powered by batteries which lasts up to 8 hours on marching. • It amplifies movements of user. • Loads are attached to the skeleton and are carried by the skeleton bypassing the user. • User can carry up to 90kg weight and run at a speed of 7mph for long hours.
- 26. XOS •It is alsodeveloped for military use.
- 27. XOS FEATURES • XOS2 is the most advanced exoskeleton developed so far. • Weighs 150 pounds. • It is tethered to a power generator. • Sensors are provided all over the body and joints have computer processors which communicate with each other. • Can lift up to 180kg.
- 28. LANDWALKER • It standsat 3.4 meters tall & weighs 1000 kg. • It has a cabin for the pilot. • It is powered by a 250cc petrol engine. • With guns held at each side, this robot would be intimidating to any soldier on the battlefield.
- 29. ACHIEVEMENTS • Claire Lomas,a paralyzed woman finished the London Marathon in the Rewalk bionic suit.
- 30. The 2014 FIFAWorld Cup made history when it opened in Sao Paolo this week when a 29-year-old paralytic man named Juliano Pinto kicked a soccer ball with the aid of a robotic exoskeleton.
- 31. Advantages • Disability nolonger remains as a permanent issue. • Increased mobility & performance. • Lessens the distance between men & machines. • Newer researches in specialized materials. • Improves quality of life. • Expanding markets and newer jobs.
- 32. Disadvantages • Research isdrastically expensive. • The suit is also expensive -more than $45,000. • Specialized parts are required. • Lack of adequate power source still hinders the development. • Difficult to stand up if user fell down but it has been solved to a great extent by constant research.
- 33. FUTURE • These exoskeletonswill be out in the battlefield helping & protecting our soldiers. • Robotic surgeons controlled by surgeons will soon conquer the surgery field. • Paralyzed patients can walk again. • The future seems endless as we go deeper into this.

Editor's Notes
- #31 It was the first time a mind-controlled prosthetic was used in a sporting event, and represented the culmination of months worth of planning and years worth of technical development. The basic idea is that we are recording from the brain and then that signal is being translated into commands for the robot to start moving. the exoskeleton relies on a series of wireless electrodes attached to the head that collect brainwaves, which then signal the suit to move. The braces are also stabilized by gyroscopes and powered by a battery carried by the kicker in a backpack.
