Intro

Have you ever wished that you had super powers? Well if you have, guess what they are probably going to invent something that will give you those super powers soon. ThatŐs right, they are inventing something called the exoskeleton that will enable you to jump higher, lift heavier objects and lots of other cool abilities that you can find out about in my report. So read on to find out about usage, history, and how it works.

Usage                                                                            

This paragraph is about what fields the exoskeleton will be used in. ŇAccording to Wikipedia.org, ŇIn the early 2000s a number of companies and research centers developed the first practical models of human exoskeletons. One of the main uses is enabling a soldier to carry heavy weights (80–300 kg) while running or climbing stairs. Not only can a soldier carry more weight, he can wield heavier armor and weapons. Most models use a hydraulic system controlled by an on-board computer. They can be powered by an internal combustion engine, batteries or, potentially, fuel cells. Another area of application is medical care, nursing in particular. Faced with the impending shortage of medical professionals and the increasing number of people in elderly care, several teams of Japanese engineers have developed exoskeletons designed to help nurses lift and carry patientsÓ. Pretty amazing huh .I think itŐs really cool that two countries are working on developing the exoskeleton.

 

History                                                                                

This paragraph is about the first exoskeleton prototype. According to Kevin Bonsor DARPA will not be the first to attempt to build an exoskeletal mechanical body suit. As mentioned previously, GE developed the Hardiman hydraulic and electrical body suit in the 1960s. The problem with that suit is that it was so big and heavy (1,500 pounds) that it wasn't practical. (Howstuffworks.com) But that means that if it had been practical we would probably be a lot closer to mass production.

This paragraph is about where we are now in developing it. According to Kevin Bonsor Today, there are more advanced materials, such as carbon fiber and other mechanisms available that can be used to build a more streamlined exoskeleton. However, the project is not without its challenges.

Five elements will have to come together to make an exoskeleton machine work, including the structure, power, control, actuation and biomechanics. Each of these elements comes with its own set of challenges. But still itŐs pretty amazing that were actually so far in developing it.

How it works

This paragraph is about how the Exoskeleton can lift things that are heavier than you. According to Gregory Mone, the XOS works similar to a human appendage. When you perform a bicep curl, the muscle fibers in our upper arm contract, pulling on tendons that lift our forearm. In the XOS, a sensor in the handle detects a force as the operator moves his arm. The sensorŐs data goes to the computer, which calculates how to move the exoskeleton to minimize the strain on the userŐs hand. These instructions go to a series of valves that control the flow of high-pressure hydraulic fluid to cylinder actuators in the joints. The fluid moves the cylinders, which move the cables attached to them, acting as tendons and pulling on the robotic limbs. The XOS has 30 actuators, each controlling a different joint. (http://www.popsci.com/scitech/article/2008-04/building-real-iron-man) So that basically means that there are cybernetic muscle/tendons that lift the weight for you. IsnŐt that amazing!  

       This paragraph is about how you can tell if some one is dead or alive automatically. DARPA is developing computerized fabrics that could be used with the exoskeletons to monitor heart and breathing rates. That means they could even see if they were having a stroke!

         Did you know that they will probably put phones in the helmet of the exoskeleton? TheyŐre going to put them in there so they can talk to there commanders. But maybe another use is being able to take pictures with the phone. But if they had the iPhone, according to Tracy Wilson they could automatically send tons of the pictures through e-mail. Plus they could take as many pictures as they want because there is almost unlimited storage space. (howstuffworks.com) IsnŐt that amazing! You could do all sorts of reconnaissance!  

 

Conclusion

 

       So thatŐs my report, hope you enjoyed and now you know what you need to know for when it comes out. Bye!
