1. An autonomous transport vehicle for transporting a payload, the autonomous transport vehicle comprising:
- a frame having at least four corners and at least four support wheels, the four support wheels being distributed at least proximate the at least four corners of the frame to support the frame on and contact a travel surface on which the autonomous transport vehicle travels, where the frame defines a payload support section and a drive section coupled to each other by an articulated coupling;
a transfer arm connected to the payload support section;
wherein the drive section has a motor and at least two support wheels of the at least four support wheels are disposed on opposite sides of the drive section, the at least two support wheels being drive wheels coupled to the motor.
