Robotic fire extinguishing device and handling method
A fire extinguishing robotic service device is described for use with a robotic picking system grid. The fire extinguishing robotic service device is configured for driving to any location on the grid in order to extinguish a fire. The service device may also be provided with a camera sensor to locate the fire.
1. A robotic picking system, comprising:
a storage system comprising: two substantially perpendicular sets of rails forming a grid; and stacked containers located beneath the rails of the grid;
the storage system comprising at least one fire extinguishing robotic service device, the fire extinguishing robotic service device comprising:
a body defining containing means that contains fire extinguishing material;
two sets of wheels upon which the body is mounted, a first set of wheels engaging with at least two rails of a first set of rails, a second set of wheels engaging with at least two rails of a second set of rails, one of the first or second set of wheels independently moveable and driveable with respect to the other of the first or second set of wheels such that only one set of wheels engages with the first and second sets of rails at any one time such that movement of the fire extinguishing robotic service device along rails to a first grid point that is over a first column is achieved by driving only the set of wheels engaged with the rails; and
a spray device dispensing the fire extinguishing material from the containing means of the fire extinguishing robotic service device, wherein the spray device includes a pump that dispenses fire extinguishing material towards a second grid point such that the fire extinguishing material descends a second column of the storage system within which a fire is located, wherein the first column is adjacent the second column.
2. The system according to claim 1 , wherein the fire extinguishing robotic service device further comprises:
a fire detecting means.
3. The system according to claim 1 wherein the fire extinguishing material is selected from a group consisting of gel, powder, foam, aerosol, fluid, gas, pellets liquid and water.
4. The system according to claim 2 , wherein the fire detecting means is selected from a group consisting of a smoke detector, a heat sensor, an optical sensor, and an audio sensor.
5. The system according to claim 1 , wherein the fire extinguishing robotic service device further comprises:
a camera means providing a vision system to allow observation of a fire remotely.
6. The system according to claim 1 , further comprising a hose and a hose reel supplying the fire extinguishing material to the fire extinguishing robotic service device.
7. The system according to claim 6 , wherein the hose reel is movably carried on an edge of the system by a structural member.
