Abstract: In one embodiment, an inventory storage module has first to fourth conveyor segments that define a conveying loop. The module translates storage totes around the conveying loop using, at least in part, first and second actuator assemblies. The first actuator assembly has a first actuator and a first crossbar connected to the first actuator. The first actuator assembly moves the first crossbar in a first direction such that the first crossbar engages and pushes totes along the first conveyor segment in the first direction. The second actuator assembly has a second actuator and a second crossbar connected to the second actuator. The second actuator assembly moves the second crossbar in a second direction, opposite the first direction, such that the second crossbar engages and pushes totes along the second segment in the second direction. The third and fourth segments transfer totes between the first and second segments.

Abstract: In one embodiment, an inventory storage module has a pair of upper tracks and a pair of lower tracks that are connected to one another so as to define a closed movement path in a vertical plane. The module has a plurality of carriers arranged end-to-end along the upper and lower tracks. Each carrier is elongate along a direction that extends between a pair of the upper or lower tracks so as to carry a set of the storage containers that are arranged side-by-side. Each carrier has first and second first wheel assemblies that couple the carrier to the pairs of upper tracks and lower tracks when supported by the pairs of upper tracks and lower tracks, respectively. The storage module can move the inventory carriers around the movement path until a desired one of the inventory carriers is presented at one of the first and second ends.

Abstract: In one embodiment, an storage module has first and second guide rails that are spaced from one another along a lateral direction. Each guiderail has an upper track and a lower track spaced from one another along a vertical direction, and first and second connecting tracks that connect the upper track to the lower track at first and second ends, respectively. A plurality of inventory carriers that are supported between the guiderails and are arranged end-to-end along the upper and lower tracks. A drivetrain drives the carriers to translate along the upper and lower tracks at a first speed, and drives the carriers to translate along the connecting tracks at a second speed, faster than the first speed. Increasing the speed of the carriers at the connecting tracks can prevent the carriers from colliding with one another when transitioning between the upper track and the lower track.

Abstract: In one embodiment, an end effector for a robotic manipulator has a base that is configured to attach to the end of a robotic arm, a first fork, and a second fork. The end first fork includes a first pair of prongs that extend from the base along a first direction and that are spaced from one another so as to receive a first storage container therebetween. The second fork includes a second pair of prongs that extend from the base along a second direction that is angularly offset from the first direction and that are spaced from one another so as to receive a second storage container therebetween. The first and second forks can be used to stack or unstack the first and second containers.
