Human Robotic Systems (HRS): Extreme Terrain Mobility: Exoskeleton Development for ISS Evaluation

Completed TRL 4 (started at 4, targeting 5)

Description

In FY12, HRS and GCD developed the X1 exoskeleton with the ultimate intent of augmenting crew endurance/strength in future missions.  Offshoots of the technology involved lightweight exercise devices for ISS and strength measurement by using the torque sensing in the X1’s joints.  The objectives for exoskeleton development in FY14 are:

Benefits

The X1 exoskeleton is a multi-functional device in the emerging field of wearable robotics. Its space applications include:

On earth, the same technology can be applied to aid in assistive mobility. 

During FY14, components from the X1 exoskeleton will be iterated, specialized and evaluated for use in space. 

The first product will be a prototype ankle exoskeleton, which will provide capability beyond the passive ankle in the X1 prototype.  The new ankle exoskeleton device will be delivered to the Space and Life Sciences Directorate at JSC for evaluation as an exercise device.

The second new development will be the design of a single-joint knee dynamometer.

The current state of the art of exercise equipment onboard the International Space Station is the ARED device, which weighs 320 kg.  The X1 exoskeleton has the ability to significantly reduce the mass of crew exercise equipment for missions beyond low earth orbit to about 50 kg or less.

For the space program, the exoskeleton and exoskeleton devices can be worn in zero gravity to provide exercise resistance, which helps stave off bone and muscle loss.  The new approach of using the X1 joints as a dynamometer, to measure and evaluate astronaut strength on-orbit, could give the life sciences doctors new tools and access to new data to study the effects of zero G on humans as well as evaluating the potential benefits of wearing resistive exoskeleton technology to help counteract the deleterious effects of prolonged exposure for zero G. The technology could also eventually lead to assistive exoskeletons to add strength and endurance for astronauts when in cumbersome space suits, on ISS or under the influence of gravity on the moon or Mars.

In addition, HRS’s exoskeleton technology has already been demonstrated for use in providing mobility to humans with disabilities. Ultimately this technology could enable paraplegics to walk again, could assist disabled veterans, and could provide renewed mobility and strength for those with certain muscular disabilities.

How to get involved

This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
