Exoskeleton in the pants gives longer running rounds
US and South Korean researchers have invented an exoskeleton that reduces the energy consumption of running by four percent. Now they are trying to make the skeleton lighter, so you can save even more energy.
A new exoskeleton gives the runner an energy saving of seven percent when activated. The savings are four percent compared to when the runner does not have the equipment.
Extend your daily run by four percent without consuming extra energy. Or better yet – extend the distance you can manage by nine percent.
This is now possible with a newly developed exoskeleton that enhances the natural movements of the legs as you walk and run.
The invention has been made by a group of American and South Korean researchers. In the distance, it looks like a couple of longer shorts, but if you look closer, it is more than that.
On the stomach, the runner has a battery strapped. Over the lumbar is the active part of the exoskeleton. It consists of a pair of so-called actuators, which pull in several ropes that are connected to the back of the thighs.
The pulls in the ropes help the muscles and buttocks to move the leg back with the body’s center of gravity.
Sensors built into the shorts continuously record the movements of the muscles and ensure that the exoskeleton works at exactly the same pace.
The energy savings is going to be even higher if the researchers manage to make the exoskeleton easier. Today it weighs five kilos.
In the long term, the goal is not just to make the trip more comfortable and the walk longer for all of us.
The researchers hope that the invention will lead to new types of exoskeleton that can help patients during rehabilitation and be a support for people with tasks that consist of substantial bodywork.
