Abstract
An autonomous transport robot for transporting a payload is provided and includes a frame with an integral payload support, a transfer arm connected to the frame for autonomous transfer of payload to and from the frame, and a drive section with at least a pair of traction drive wheels astride the drive section, the drive section being connected to the frame. The at least the pair of traction drive wheels have a fully independent suspension coupling each traction drive wheel of the at least the pair of traction drive wheels to the frame, with at least one intervening pivot link between at least one traction drive wheel and the frame configured to maintain a substantially steady state traction contact patch between the at least one traction drive wheel and a rolling surface over rolling surface transients throughout traverse of the at least one traction drive wheel over the rolling surface.
