SAFETY DEVICE FOR A REMOTELY OPERATED VEHICLE, A SYSTEM AND A METHOD OF IMPROVING THE OPERATIONAL SAFETY OF A GRID SYSTEM

Abstract: a remotely operated delivery vehicle for transport of a storage container between an automated storage and retrieval grid, which is configured to store a plurality of stacks of storage containers, and an access station for handling of the storage container by at least one of a robotic operator and human operator. the remotely operated delivery vehicle comprises a vehicle body comprising a motor for driving a plurality of rolling devices for moving the remotely operated delivery vehicle in a horizontal plane; a control unit for controlling the remotely operated delivery vehicle; and a container carrier provided above the motorized vehicle body for carrying a storage container. the remotely operated delivery vehicle comprises a safety device which transmits a signal to the control unit such that it performs an action of operating the remotely operated delivery vehicle, in the event that a collision is detected. the collision is caused by a force acting on the remotely operated delivery vehicle and is detected by a collision mechanism of the safety device and the collision mechanism is a container carrier displacement device arranged such that it trips the safety device upon displacement of the container carrier relative to the motorized vehicle body, which first position is the undisplaced position and the second position is the displaced position.
