About the Company

Humble Robotics

Autonomous, cabless EV haulers for freight

Humble Robotics builds fully autonomous, cabless, battery-electric Class 8 haulers designed to move freight dock-to-dock in warehouses, railyards, and seaports, starting with shipping-container moves. The trucks navigate using 360° cameras, LiDAR, and radar, and run vision-language-action models to drive themselves, with remote operational support as part of a full-service offering. Unlike many competitors, Humble leverages a cabless, lighter-weight design for better payload efficiency, and it brings together a team with experience from Tesla, Waymo, Cruise, Google, Rivian, Apple, Uber, and Waabi. The company aims to advance the autonomy stack, launch pilots, and begin early manufacturing to support eventual public-road deployment.
