FLOAT: Flexible Levitation on a Track

Completed

Description

The FLOAT system employs unpowered magnetic robots that levitate over a 3-layer flexible film track: a graphite layer enables robots  to passively float over tracks using diamagnetic levitation, a flex-circuit layer generates electromagnetic thrust to controllably propel  robots along tracks, and an optional thin-film solar panel layer generates power for the base when in sunlight. FLOAT robots have no  moving parts and levitate over the track to minimize lunar dust abrasion / wear, unlike lunar robots with wheels, legs, or tracks.  

Benefits

FLOAT tracks unroll directly onto the lunar regolith to avoid major on-site construction -- unlike conventional roads, railways, or  cableways. Individual FLOAT robots will be able to transport payloads of varying shape / size (>30 kg/m^2) at useful speeds (>0.5  m/s), and a large-scale FLOAT system will be capable of moving up to 100,000s kg of regolith / payload multiple kilometers per day.  FLOAT will operate autonomously in the dusty, inhospitable lunar environment with minimal site preparation, and its network of  tracks can be rolled-up / reconfigured over time to match evolving lunar base mission requirements.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

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.
