Aspects herein relate to using motor velocity as feedback for controlling the extension or retraction of jacks for control of the angular orientation of a structure, or other means for accomplishing the same. Embodiments include a structure orientation control apparatus comprising one or more jacks configured to support a structure, one or more jack drive mechanisms coupled to at least one of the one or more jacks, the one or more jack drive mechanisms configured to extend or retract the one or more jacks, and a jack controller configured to cause the one or more jack drive mechanisms to extend or retract the one or more jacks based on a jack command. The jack controller may be configured to monitor one or more jack velocities during extension or retraction.

Aspects of the disclosure relate to an engine support system and method. The engine support system includes a frame mounted engine support and at least one engine mounted coupler. The engine support includes a frame mount with an elongated body and opposing arms slidably disposed on the elongated boy for releasably engaging a frame of a vehicle, and at least one jack assembly. Each jack assembly includes a collar coupled to and horizontally movable along the elongated body, and a jack rod coupled to and vertically movable relative to the collar. The jack rod includes a ball mount configured to insert into the coupler at an underside of an engine block of the vehicle. Each jack assembly is configured to support and/or lift the engine block relative to the vehicle frame by vertical movement of the ball mount into the coupler and relative to the frame mount engaged with the vehicle frame.

The present invention discloses an inventory item management system, transporting robots and the method for transporting inventory holder, wherein the transporting robot comprises a lifting unit and a horizontal rotation unit, the lifting unit comprises a first power unit, a lifting shaft and a first supporting part, and the first power unit configured to drive the first supporting part to move along the lifting shaft; the horizontal rotation unit comprises a second supporting part and a second power unit which drives the second supporting part, and the second supporting part and the first supporting part are connected rotatably. The lifting unit has a hollow hole which is disposed in vertical direction internal to the lifting unit, and the lifting shaft is located on one side of the hollow hole. The inventory item management system of the present invention transports the inventory holder with required items to the manual picking table automatically via the transporting robots, and the transporting robots again carry the inventory holders they transported back to the designated positions after manual picking. The present invention increases the transport efficiency of the transporting robots and the management efficiency of the entire inventory item management system, and reduces the costs.
