Exoskeleton-Based Exercise and Training Device

Abstract

A wearable robotic device configured to provide exercise for a human user. A primary use of the device is to address muscle and bone density loss for astronauts spending extended periods in microgravity. In one configuration the device applies a compressive force between a users feet and torso. This force acts very generally like gravity—forcing the user to exert a reactive force. The compressive force is precisely controlled using a processor running software so that a virtually endless variety of force applications are possible. For example, the wearable device can be configured to apply a gravity-simulating force throughout the device's range of motion. The robotic device may also be configurable for non-wearable uses. In these cases the robotic device may act as an exercise machine. The programmable nature of the force application allows the device to simulate weight-training devices and other useful exercise devices. The device's functions may be implemented in a microgravity environment or a normal terrestrial environment.

AI Technical Summary

Benefits of technology

The present invention is a wearable robotic device that helps to exercise bodily muscles and bones that are prone to lose strength during long periods of microgravity. The device applies a compressive force between the user's feet and torso, simulating gravity to force the user to exert a reactive force. The force application can be controlled using software to mimic various weight training devices. It can be used both in microgravity and regular terrestrial environments.

Problems solved by technology

Extended weightlessness causes bone loss and other undesirable effects on the human body.

Since the body's structures are not used for support and balance, muscle mass tends to be lost over time and the bones tend to become less dense.

Designing such devices is difficult, since reaction forces must be countered in order to keep the astronaut in one place.

Another important factor is the space consumed by the device.

Future missions likely will not have the luxury of a dedicated exercise area.

In addition, it is often difficult for an astronaut to dedicate a large block of time purely to exercise.
