Apparatuses, systems, and methods for receiving a part from another system. An apparatus includes a platform configured to receive a first part and a second part to be unloaded from another apparatus. The apparatus further includes a first guide member and a second guide member. The first guide member and the second guide member are configured to engage with, respectively, a first engaging member and a second engaging member on another apparatus and enable the first part and the second part to be unloaded. The first guide member and the second guide member may be configured to contact, respectively, the first engaging member and the second engaging member to actuate a first gate member connected to the first engaging member and a second gate member connected to the second engaging member to move to open positions to enable the first part and the second part to be released.

A work machine includes a relief valve that is installed in a hydraulic line that forms a closed circuit between a hydraulic pump and a hydraulic motor, and sets a relief pressure of the hydraulic line; a braking device that brakes a traveling device attached to the hydraulic motor; and an operation mechanism that operates the braking device. When a traveling speed of the traveling device is equal to or more than a predetermined threshold, the relief pressure is changed from a first pressure that is a pressure before a braking operation is performed by the operation mechanism to a second pressure that is lower than the first pressure.

A method of operating a bin storage system includes a plurality of storage columns for storage of a plurality of vertically-stacked storage bins and a plurality of robot vehicles for transporting storage bins. A plurality of supporting rails are arranged in a two-dimensional matrix at the top of the columns. The supporting rails are arranged in a first direction and a second direction orthogonal to the first direction. The method includes positioning a cavity displaying a downwardly facing opening for the storage bin of one of the plurality of robot vehicles such that the cavity is aligned with one of the storage columns to permit the cavity to receive a storage bin from the storage columns, receiving a storage bin from the storage column into the cavity, and moving the robot vehicle along the bin storage system, using a plurality of wheels attached to the robot vehicle. A first set of wheels is arranged to allow the robot vehicle to travel in the first direction along the supporting rails. A second set of wheels is arranged to allow the robot vehicle to travel in the second direction along the supporting rails. At least one of the first set of wheels and the second set of wheels are configured to be displaceable from the supporting rails, such that the first set of wheels are in contact with the supporting rails when the robot vehicle travels in the first direction and the second set of wheels are in contact with the supporting rails when the robot vehicle travels in the second direction.
