FedEx is expanding its use of Dexterity’s autonomous trailer-loading robots at its Hagerstown, Maryland, facility after several years of development and testing. FedEx and Dexterity did not say how many robots will be installed or provide a timeline for a bigger rollout. Trailer loading is one of the most physically demanding jobs in parcel shipping, requiring strength, endurance, and the ability to make quick decisions as packages arrive. Dexterity’s Mech robot has two arms and is compact enough to work inside a trailer. It is powered by the company’s Foresight system, which uses sight, depth sensing, and touch to make loading decisions in real time.
