The plurality of second wireless transceivers are configured to detect the first wireless signal and transmit a plurality of second wireless signals in response to detecting the first wireless signal. The first wireless transceiver is configured to detect the plurality of second wireless signals. The processing circuit is communicably coupled to the first wireless transceiver. The processing circuit is configured to determine a position of the portion or component based on information acquired from the first wireless transceiver.

An automated storage and retrieval system includes a storage array of storage locations for case units. An in-out case conveyor is capable of bi-directionally transporting case units to and from the storage array, and an in-out loaded pallet conveyor is capable of bi-directionally transporting loaded pallets towards and away from the storage array. A palletizer-depalletizer cell includes a bi-directional pallet transport system with more than one independently driven pallet transports, each with a different pallet holder independently movable relative to a cell frame. Placement of case units commissioning a pallet layer loading a pallet, and removal of case units decommissioning a pallet layer unloading another pallet are both effected at the common pallet layer interface at a predetermined level of the cell frame. The pallet transports independently index a first and a second of the different pallet holders, each independently holding the pallet loading at the common pallet layer interface.

Provided is a travel operation device for a crawler aerial work vehicle equipped with an operation panel that can be operated with one hand and that provides stable operating conditions even when swayed from side to side. A travel operation device 10 comprises an operation panel 11 that is disposed on the deck 4 of a self-propelled crawler aerial work vehicle 1 and a controller 70 that controls the rotation of a left-side motor 60a, which drives a left-side endless track, and a right-side motor 60b, which drives a right-side endless track, according to the operation of an operating stick 20 that is disposed on the operation panel 11. The operating stick 20 of the operation panel 11 is composed of: an operating stick body 21 that can be tilted only in one axial direction back and forth from the neutral position; a left-swivel switch 24; a right-swivel switch 25; and an enable switch 22 that enables the operation of the switches. The switches are arranged at positions on the operating stick body 21 where the left-swivel switch 24 and/or the right-swivel switch 25 can be operated while the enable switch 22 is pressed with fingers gripping the operating stick body 21.

An autonomous guided vehicle includes a chassis with a power supply and powered sections that are connected to the chassis and powered by the power supply. The powered sections include a drive section, a payload handling section, and a peripheral electronics section. A controller of the vehicle includes a comprehensive power management section communicably connected to the power supply so as to monitor a charge level of the power supply. The comprehensive power management section is connected to the drive section, the payload handling section, and the peripheral electronics section respectively powering the drive section, the payload handling section, and the peripheral electronics section from the power supply. The comprehensive power management section manages power consumption of branch circuits, of the powered sections, based on a demand level of each branch circuit relative to the charge level available from the power supply.

A load alignment aid with range finding sensors positioned diagonally on a mounting platform to calculate range, vertical alignment, and horizontal alignment. Each sensor measures a distance (d) from the mounting platform to the load. Where d(1) does not equal d(2) and d(1) does not equal d(3), a misalignment due to tilt or chassis misalignment is detected. The aid further includes a display which may show a graphic representation of the approach to a load and an alert for misalignment notification.
