A remotely operated vehicle assembly for picking up storage bins from a bin storage system, the remotely operated vehicle assembly comprising: - a vehicle body displaying a cavity for receiving a storage bin stored within the bin storage system, - a vehicle lifting device (9, 9a) connected to the vehicle body for lifting the storage bin into the cavity, - driving means (10,11) comprising a first set of vehicle rolling means connected to the vehicle body, allowing movement of the remotely operated vehicle assembly along a first direction within the bin storage system during use, and a second set of vehicle rolling means connected to the vehicle body, allowing movement of the remotely operated vehicle assembly along a second direction in the bin storage system during use, the first and second directions (X, Y) being arranged perpendicular to each other, characterised in that the first and second sets of vehicle rolling means (10,11) comprise a first part and a second part being arranged at opposite facing side walls of the vehicle body, where the first and the second part (10a, 10b) is rigidly connected to a first and second displacement plate (34a,34b), respectively, and a vertically displaceable bar at a lateral plane above the cavity is rigidly connecting the first and second displacement plate (34a,34b), and - a displacement arrangement coupled to the driving means (10,11), comprising a displacement motor configured to provide the power to displace at least one of the first set of vehicle rolling means and the second set of vehicle rolling means between a displaced state where the vehicle rolling means (10,11) is displaced away from the underlying bin storage system during use, and a non-displaced state where the vehicle rolling means (10,11) is in contact with the underlying bin storage system during use, and wherein the displacement motor is situated in a lateral plane above the cavity, and further configured to generate a power that is converted to a vertically directed pressure force acting on the first or the second set of vehicle rolling means (10,11). - a vehicle body displaying a cavity for receiving a storage bin stored within the bin storage system, - a vehicle lifting device (9, 9a) connected to the vehicle body for lifting the storage bin into the cavity, - driving means (10,11) comprising a first set of vehicle rolling means connected to the vehicle body, allowing movement of the remotely operated vehicle assembly along a first direction within the bin storage system during use, and a second set of vehicle rolling means connected to the vehicle body, allowing movement of the remotely operated vehicle assembly along a second direction in the bin storage system during use, the first and second directions (X, Y) being arranged perpendicular to each other, - a displacement arrangement coupled to the driving means (10,11), comprising a displacement motor configured to provide the power to displace at least one of the first set of vehicle rolling means and the second set of vehicle rolling means between a displaced state where the vehicle rolling means (10,11) is displaced away from the underlying bin storage system during use, and a non-displaced state where the vehicle rolling means (10,11) is in contact with the underlying bin storage system during use, and wherein the displacement motor is situated in a lateral plane above the cavity, and further configured to generate a power that is converted to a vertically directed pressure force acting on the first or the second set of vehicle rolling means (10,11).
