Claim of US Patent No. 10,988,323

1. A maintenance system for assisting in maintaining an automated carrier system for moving objects to be processed, said maintenance system comprising:an array of disconnected track sections mounted on a floor, each track section being rectangular in shape;
a plurality of automated carriers, each said automated carrier comprising a carrier body and a plurality of wheels mounted to the carrier body for moving the automated carrier along the array of disconnected track sections; and
an automated maintenance carrier comprising a substantially planar maintenance body and a plurality of wheels mounted to the substantially planar maintenance body for moving the automated maintenance carrier along the array of disconnected track sections, wherein the substantially planar maintenance body is larger in at least one of a length direction and a width direction than any of the rectangular track sections,
wherein the automated maintenance carrier further comprises an articulated robotic arm mounted on the substantially planar maintenance body, wherein the articulated robotic arm has an extendable end effector that extends to grasp a disabled automated carrier on the array and retracts to tow the disabled automated carrier onto the substantially planar maintenance body of the automated maintenance carrier.
