Launched in March 2025, it can lift up to 130 lb (about 59 kg), place boxes as high as 8 feet, sees with up to 16 onboard cameras and runs Dexterity's Foresight physical-AI world model. In July 2026 FedEx expanded Mech trailer-loading from a pilot to a larger production deployment at its Hagerstown, Maryland hub.
