Humble Robotics raises $51 million Series A to develop autonomous freight vehicles

The Hauler is a cabless Class 8 electric freight vehicle that combines tractor, trailer and driver into a single unit. It features a 200‑mile range, 55 mph top speed, L4‑capable sensor pods with cameras, lidar and radar, and a vision‑first AI foundation model that requires no pre‑mapped routes. Designed for regional dock‑to‑dock routes under 250 miles—accounting for 87 % of U.S. truck tonnage—the platform can move 40‑foot international and 53‑foot U.S. containers, charging at depots while loaded. The Series A will fund customer pilots, testing, validation and early manufacturing as Humble aims to prove its integrated vehicle, AI and service model for reliable short‑haul freight operations.
