Patent ID: 11661280

Abstract:
A container handling vehicle for picking up storage containers from a three-dimensional grid of an underlying storage system includes a first set of wheels, for moving the vehicle along a first direction on a rail system in the grid; and a second set of wheels, for moving the vehicle along a second direction on the rail system in the grid, the second direction being perpendicular to the first direction. A vehicle body includes walls on all sides and forms a quadrilateral footprint. The footprint is defined by horizontal peripheries in the first and second directions of the vehicle body. The container handling vehicle further includes a first section and a second section arranged side-by-side such that a centre point of a footprint of the first section is arranged off centre relative a centre point of the footprint formed by the vehicle body. The first and second sections are separated by a divider element. The first set of wheels includes two pairs of wheels, including a first and third wheel and a second and fourth wheel, respectively, arranged on opposite portions of the first section, wherein the first and third wheel of the first set of wheels are connected to the vehicle body and the second and the fourth wheel of the first set of wheels are connected to the divider element. The second set of wheels includes two pairs of wheels, including a first and third wheel and a second and fourth wheel, respectively, arranged on opposite portions of the vehicle body. Two of the wheels in the second set of wheels are arranged on opposite sides of the second section and the other two wheels in the second set of wheels are arranged on opposite sides of the first section. A size ratio of a footprint of the first section relative a footprint of the second section is at least 2:1. The first section is configured to accommodate a storage container, and the second section comprises at least a first battery.
