    摘要: A storage setup and method for robotic delivery and retrieval of crates from shelving blocks are disclosed. At least one shelving block in the setup comprises non-uniformly spaced apart storage surfaces. The storage surfaces are accessible to lift-robots through a network of tracks comprising intersecting vertically and horizontally oriented tracks. A computerized control system is configured to differentiate between storage locations based on which crate sizes from at least two different ranges of crate sizes a storage location can store. The storage may be automatically optimized by routing robots to store crates in storage locations sized in correlation with the size of the crate to be stored.

    摘要: A method for turning a pinion-driven lift-robot in an intersection of rails. Moving the pinion-driven lift-robot in a first motion mode to position the pinion-driven lift-robot in a first position at the intersection. The pinion-driven lift-robot is turned over a corner of the intersection that is accessible from the first position and that includes continuous rails connecting a vertical track and a horizontal track, whereby positioning the pinion-driven lift-robot in a second position at the intersection. The pinion-driven lift-robot is moved in a second motion mode towards a designated direction.

    摘要: A direction switching module for lift robots using a pair of pinions coupled to a rack for propelling vertically and horizontally according to the track's orientation, is disclosed. In a linear motion mode both pinions rotate in the same velocity. In a direction switching mode, when changing from vertical to horizontal motion mode and vise versa, the module is capable of propelling one pinion on a vertical track and its counterpart on a horizontal track, simultaneously, each pinion in a different velocity. A bogie propelled by two pairs of said module is also disclosed, and a controller configured to drive both pinions in same velocity during linear motion and each pinion in a separate appropriate velocity during the direction switching mode. A method for turning a pinion-driven lift-robot in an intersection of rails and a controller for controlling the linear motion modes and the direction switching modes of the lift robot are also disclosed.
