Running for long is not easy. A lot of stamina is required for that. Your own body weight also makes it a burden to carry the weight and the run. At Harvard, they might help you as their Robotic shorts now make it easier to run for hikers. Researchers at Harvard made a new robot powered shorts. It doesn’t give you stamina or any superpowers. But it does make you feel few pounds lighter, so you can run more often. More than you usually do on normal conditions and stamina.
Robotic shorts now make it easier to run
The 11 pound system seems to be made with lot of internal structures, holding you in an axial position. Or as they claim it as a holding position. When you wear the shorts, you feel yourself more flexible. More light. It also proved for some testers, that they can run better. In fact they can run more distances. This is highly of a benefit for those people, who has to cover a lot of distances. Even for rescue workers.
Robotic shorts now and before
The journal to which the paper was published, mentioned that it kind of works on a different mechanism. Earlier exosuits and exo skeleton gave people additional powers to do better jobs. And even 5 times more strength. While this small pant, does opposite. It actually makes you feel lighter, more flexible in the air. In other words, you have the same strength, just more light.
The pant mechanism skeleton works by adjusting to its joints, as you walk or run. If your run it, switches to another set of controls. This is what gives you the additional control over running. Plus less weight. As you walk in a position similar to an inverted pendulum, your mass accommodates as you move on. The shorts work on that mostly.
How robotic shorts make it easier to run?
The pants has a cable system in itself at the back, that are connected to a motor that drives them. well not in the actual sense as seen in pulleys. But in a multi-angular system. When one leg is lifted by the hiker, the cables assist it in its movement.
So the motion becomes less of a burden, thus counterfeiting better leg. This involves a less accumulation and use of energy. Since the extra help is provided by the gear. Thus the robotic short now make it easier to run. Not just for hikers, but anybody.
Experimentations on the Robotic shorts made yet
Researchers provided the shorts to some athletes, to check on how it optimizes itself during runtime. Their prior data was consumption of oxygen. (As this is what gives us energy during metabolism). The metabolism were actually on normal rates for a 30% greater time. While as they calculated, the rate of decline came to just 4% for running.
And around 9% for walking. Back tracking this data, researchers found it was near to less of 16 pounds lighter. While the exosuit has its own weight of around 11 pounds, it was not counted. While it added weight, the engineers are developing another that should weigh less on 7 pounds.
How robotic shorts can be applicable?
Long distance hikers can really benefit from this. As fatigue gets in the way of walking, robotic shorts can make a bigger difference for them. The researchers mentioned how it could help patients with disabilities to improve and get better. As the shorts can around 40% to get their paralyzed muscles relax, even open up to sense. This can heal them back, thus restoring movement.
Even in the Defence Advanced Research Project Agency, their journal suggests it can help military guys. The current prototype can also be useful for shorter tasks, with a better battery power. As they have to carry over good weights for a longer distance. It would be a good help to reduce the strain on the path. Well, the Warrior Web program is actually doing its extensive research in the same field.
Probable cons of the robotic shorts
While the video footage that show how the shorts fit into, it does not look that good. There is a sizable bulk in the inner thigh areas. It could be a bit uncomfortable during resting periods after a jog. The back lower seems to be point bulky. As carrying backpacks is not that of a good idea after wearing the pants. The suit does counteract well for the current male walking styles. As broader hip movement enhanced pants will be made for females too.
