The capability, marketed as part of the company’s Remote Control System Galileo, was shown off to defense companies at the International Defense Exposition and Conference (IDEX) in Abu Dhabi in February, and it drew attention from a major defense contractor. But like all such collaborations, it may have gotten caught up in the companies’ legal departments.
