Humble Hauler: the cabless autonomous truck that aims to eliminate freight transport costs

Humble Robotics has unveiled the Humble Hauler, a fully cabless electric autonomous truck designed to move 40 and 53-foot containers within ports, rail terminals, and warehouses. The California startup based in San Francisco made its public debut with a $24 million funding round led by Eclipse, and has already completed its first prototype in less than six months.

A project that starts from the trailer, not the tractor

The conceptual difference from all other autonomous truck projects is radical: instead of starting with the classic Class 8 tractor and removing the driver's seat, Humble has redesigned the entire container chassis as an autonomous vehicle from the outset. The result is a platform that combines tractor, trailer, and driver into a single element, all without a cab, steering wheel, or driver's seat. As CEO Eyal Cohen, a former Tesla and Waymo executive, explains, the goal is to "bring automation to the loading dock", something that no one had realized in this way.

The absence of a cab brings concrete structural advantages: the vehicle is about 20% lighter than a traditional cabbed tractor, resulting in increased load efficiency. In terms of perception, the cabless configuration eliminates the typical blind spots of the front pillar and allows the installation of a 360-degree sensory system unobstructed by the structure of the cab itself. The setup includes automotive cameras, LiDAR, and radar.

The autonomy system does not rely on predefined rules or a purely visual pipeline: Humble has developed its own Vision-Language-Action (VLA) model, which allows the vehicle to reason around scenarios it has never encountered during training and find operational solutions in real time. The company claims that this approach reduces the time-to-market compared to traditional systems and enhances safety in unstructured environments. The declared level of autonomy is Level 4, applicable in controlled areas where the system is designed to operate.

As for the powertrain, it is fully electric with eAxle technology on two powered axles. The declared range is 320 km with a maximum speed of 90 km/h. The vehicle is sized to be only slightly longer than a standard 40-foot container, which is a direct advantage of the cab elimination, while it can be towed by any Class 8 tractor if necessary. The operation is designed exclusively for the so-called intermediate haul: handling from dock to dock in controlled environments, not long-distance transportation on public roads.

The platform is designed to be modular: the container application is the first, but Humble has already shown renderings of a six-wheel concrete mixer and different configurations for various logistical scenarios. The company plans to launch pilot programs soon with various logistics partners, with real autonomous driving tests in operational environments. The target market is the U.S. freight transport on road, valued at over $900 billion.
