Wearable robots, also known as exoskeletons, are being developed to assist humans by enhancing physical strength and mobility for applications in industries like healthcare, military, and manual labor. Early exoskeleton prototypes date back to the 1960s but the technology is rapidly advancing, with current prototypes helping people with disabilities walk and assisting soldiers in carrying heavy loads for long periods of time without fatigue. If development continues at its current pace, exoskeletons may start assisting medical professionals, laborers, and soldiers within the next 5 to 10 years.

- 2. What are Wearable Robots? Wearable robots are people-oriented robots designed to be worn. These robots are designed around the function and shape of the human body and the human will be able to control the robotic limbs. This control can assist in walking, running, jumping higher or even lifting objects one would not normally be able to lift. Those examples are only some of the most basic ways that engineers hope these robots will be used for. They hope they can use these robots to assist in medical care as well as in the military. These exoskeletons could help to protect soldiers, lighten the weight they must carry while also allowing them to move quicker.
- 3. History The first attempt to create a powered exoskeleton came in the 1960’s. General Electric was the first mover into this field of exoskeletons. The Hardiman was created by General Electric with the intention of being used for bomb loading on aircraft carriers and underwater as well as space construction. Unfortunately for General Electric, by 1970 only one arm had been created. This arm could lift 750 pounds, but itself weighed almost three quarters of a ton. Each attempt they made to create a leg that could easily be lifted failed and The Hardiman was soon dismissed from the developmental world.
- 4. Disruptive Technology Wearable robots are most definitely a disruptive technology. If and when these exoskeletons are put into use in the medical and/or military fields, we will see life-altering changes to everyone involved. They are improving upon the field of prosthetics. If a person is in an accident and loses an arm or a leg, they could get a prosthetic arm or leg. The exoskeleton may one day be able to replace this prosthetic arm by connecting a robotic arm which would connect to the neurons in your brain which would then allow you to control the arm as if it were your own.
- 5. DARPA DARPA, the United States Defense Advanced Research Projects Agency, is funding a $50 million project known as “Exoskeletons for Human Performance Augmentation”. The DARPA program hopes to allow soldiers to carry larger weapons, protect against enemy fire or chemical attack, provide stamina and allow for more food, water, ammunition and field supplies to be brought along. It is even believed that one day “exoskeletons may be programmed to bring injured soldiers back to base by themselves.” These exoskeletons will rely on hydrocarbon or chemical fuels which will allow the soldiers to independently control the robot in the field
- 6. Military Benefits of an Exoskeleton The exoskeleton will protect a soldier from enemy fire by repelling bullets. It will also allow the soldier to do more without getting as tired. This will increase the soldiers efficiency which should allow us to decrease the amount of soldiers used which in turn would of course prevent the casualties of many soldiers. If the advancements are made, an exoskeleton may even be able to carry a wounded soldier back to base, once again possibly preventing the death of a soldier. You cannot measure the importance of a human life and these wearable robots should be able to prevent us from having to when it comes to the military.
- 7. Medical Benefits of the Exoskeleton Jacob Rosen, an associate professor of computer engineering in the Jack Baskin School of Engineering at the University of California, Santa Cruz, is trying to use his expertise to defeat biomedical problems. He hopes to help people who are disabled by degenerative diseases or stroke. According to Rosen, "People with muscular dystrophy and other neuromuscular disabilities could use the exoskeleton to amplify their muscle strength, and it could also be used for rehabilitation and physical therapy."
- 8. Assistance in Physical Therapy The idea of the exoskeleton being used in physical therapy will help speed up the recovery time because the patient won’t have to rely on pre-determined hours set forth by a physical therapist. They can work on their recovery at their own pace, which in most cases would be faster than the pace they would have if they needed to follow a specific regimen set forth by a physical therapist.
- 9. “Haptic” Technology “Haptic” technology provides an interface with the user through the sense of touch, and using the exoskeleton as a haptic device has many applications in scientific visualization and manipulation, gaming, and simulation. Haptic feedback is also needed in surgical robotics to give the surgeon a sense of touch as he operates the robot from a separate console that may be located in a remote site. This advancement would help in making an envisioned fully autonomous operating room become reality. The goal is to one day allow a surgeon to control an exoskeleton from outside the operating room. They believe the exoskeleton would be able to see things that the surgeon may not be able to see from his vantage point if he were to be doing the surgery alone. While some people argue that it is unnecessary to create something to replace something that isn’t flawed, Rosen believes, “Sometimes you have to provide the tool first, and then people discover how they can use it.”
- 10. Exoskeletons in development The Berkeley Lower Extremity Exoskeleton, or BLEEX, was being created to allow “an exoskeleton that combines a human control system with robotic muscle”, according to the Director of UC Berkeley’s Robotics and Human Engineering Laboratory, Homayoon Kazerooni. In 2004, BLEEX was the most advanced exoskeleton, but since then has been overtaken by competitors.
- 11. The Landwalker Exoskeleton was created by Japanese Robotics Manufacturer Sakakibara-Kikai. It stands at 3.4 meters tall and weighs an astonishing 1000 kilograms. With guns held at each size, this mammoth of a robot would be intimidating to any soldier on the battlefield.
- 12. The HAL5, short for hybrid assistive limb, is used for civilian life and is meant to help people who have trouble walking or lifting objects. Created by Dr. Sankai, a professor at the University of Tsukuba, Japan, it is made of nickel and aluminum alloys, along with a thick plastic casing. With 25% of Japan being over the age of 65 by 2015, this technology is likely to be seen in the streets of Japan in less than a decade. The HAL5 mimics every move of its user while weighing so little it is unnoticeable.
- 13. This exoskeleton is called the Trojan and is being worked on by inventor Troy Hurtubise. The Trojan is less intellectually advanced than the other exoskeletons mentioned above but physically it has no competition. It is the 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. It also has a centered laser pointer that can be used when a soldier spots a sniper. He can call back and tell his men to “follow the dot and fire” which would easily allow for the sniper to be taken out. Troy used high impact plastic to create this 40 pound protective exoskeleton which he hopes to one day get a government contract for and get these out to the American soldiers in Afghanistan and Iraq.
- 14. Pros and Cons Pros: Cons: They vary from helping a The negatives of this disabled person to walk, technology would be if the helping in the physical enemy of your people got therapy of a person who their hands on it. It is as recently suffered a stroke, simple as that. If the people using an exoskeleton to our soldiers are out fighting perform surgery while the can perfect this technology surgeon controls the robot, before we can then we will be allowing a soldier to lift heavy in plenty of trouble. objects with no problem at all, allowing that same soldier to spend hours in the field without any fatigue setting in and letting them move quicker while carrying more food, water, ammunition and supplies. As well as protecting yourself from bullets, knives, clubs and small explosives.
- 15. Advancements and the Future The advancements of the technology in the Wearable Robots/Exoskeleton field have been booming in the past 5 years. These exoskeletons have the potential to be life-altering. We once looked at these as being the future, except now it turns out that the future is approaching much more rapidly than we had expected. Within the next 5 to 10 years we could possibly see these exoskeletons out on the battlefield helping, as well as, protecting our soldiers. Further down the road we could also see robotic surgeons in operating rooms being controlled by surgeons in another room. But most likely, even sooner than both of those options, is the potential to see these exoskeletons helping the disabled as well as people with degenerative diseases. The potential for this technology seems endless and the effects it will have on the human race will be monumental.
