AUTONOMOUS TRANSPORT VEHICLE
First Claim
1. An autonomous transport vehicle comprising:
- a frame having a longitudinal axis extending from a front of the frame to a back of the frame;
at least one first guide member mounted on one side of the frame and having a first guide member frame of reference; and
at least one second guide member mounted to an opposite side of the frame than the at least one first guide member and having a second guide member frame of reference;
wherein the first and second guide members are asymmetrically compliant guide members so that a stiffness of the at least one first guide member in response to a force in a predetermined direction relative to the first guide member frame of reference is different than a stiffness of the at least second guide member in response to the force in the predetermined direction relative to the second guide member frame of reference.

Abstract
An autonomous transport vehicle including a frame having a longitudinal axis extending from a front of the frame to a back of the frame, at least one first guide member mounted on one side of the frame and having a first guide member frame of reference, and at least one second guide member mounted to an opposite side of the frame than the at least one first guide member and having a second guide member frame of reference, wherein the first and second guide members are asymmetrically compliant guide members so that a stiffness of the at least one first guide member in response to a force in a predetermined direction relative to the first guide member frame of reference is different than a stiffness of the at least second guide member in response to the force in the predetermined direction relative to the second guide member frame of reference.

13. An automated transport vehicle for transporting items in a storage and retrieval system where the storage and retrieval system includes picking aisles adjacent item storage locations, the automated transport vehicle comprises:
-
a frame having a front end, a back end and a longitudinal axis extending between the front and back ends; a pair of first guide members are located on a first side of the frame where one of the first guide members is located adjacent the front end and the other of the first guide members is located adjacent the back end, each guide member of the pair of first guide members having a first guide member frame of reference; and a pair of second guide members are located on a second side of the frame, opposite the first side, where one of the second guide members is located adjacent the front end and the other of the second guide members is located adjacent the back end, each guide member of the pair of second guide members having a first guide member frame of reference; wherein the pair of first guide members and the pair of second guide members are asymmetrically compliant so that a stiffness of each one of the pair of first guide members in response to a force in a predetermined direction relative to a respective first guide member frame of reference is different than a stiffness of each one of the pair of second guide members in response to the force in the predetermined direction relative to a respective second guide member frame of reference. - View Dependent Claims (12, 14, 15, 16, 17)

18. A storage and retrieval system comprising:
-
a transfer deck; picking aisles in communication with the transfer deck; and at least one autonomous transport vehicle configured to traverse the transfer deck and picking aisles, the at least one autonomous transport vehicle having a frame with a front end and a back end and a longitudinal axis extending between the front and back ends, and at least one first guide member disposed on a first side of the frame and at least one second guide member disposed on a second opposite side of the frame where the at least one first guide member and the at least one second guide member are asymmetrically compliant so that a stiffness of the at least one first guide member in response to a force in a predetermined direction relative to the first guide member frame of reference is different than a stiffness of the at least second guide member in response to the force in the predetermined direction relative to the second guide member frame of reference. - View Dependent Claims (19, 20)
