Abstract

An autonomous transport robot vehicle for transporting a payload, includes a chassis that is a space frame formed of longitudinal hollow section beams, arrayed to form longitudinally extended sides of the space frame, and respective front and rear lateral beams closing opposite ends of the space frame. A payload support is connected to the chassis. Ride wheels depend from the chassis. The ride wheels and chassis in combination form a low profile height from the traverse surface to atop the chassis, where chassis height and ride wheel height are overlapped at least in part and the payload support is nested within the ride wheels. The space frame has predetermined modular coupling interfaces, each disposed for removably coupling, as a module unit, a corresponding predetermined electronic or mechanical component module of the autonomous transport robot vehicle to the chassis.
