Definitions
- Fire safety robot system comprising the fire protection robot, and method of using the same
- the present invention relates to a fire protection robot for performing a fire protection action, a fire protection system comprising the fire protection robot and a method for performing a fire protection action.
- the execution of a fire protection action is to be understood as the execution of any kind of action which can serve the purpose of (preventive) fire protection.
- the term firefighting action can be understood as combating, in particular extinguishing, and / or containing and / or preventing fires, detecting and / or verifying (potential) fires, rescuing persons in the event of a fire, and the like.
- a fire protection robot here is an unmanned vehicle, in particular a robot such as a land robot, a crawling robot and / or a drone, to be understood, which is used for the purpose of fire protection and can perform one or more fire protection actions.
- the fire protection robot In order to carry out this fire protection action efficiently, the fire protection robot must navigate as quickly as possible and directly to the location of the fire event.
- the problem here is, on the one hand, that the fire protection robot must therefore know where the fire event is, and, on the other hand, that the fire protection robot can encounter possible obstacles on the way to the fire event, which require a deviation from the direct navigation path.
- walls, doors, interior design or the like can block the way.
- fire protection robots are equipped with a device which allows a user to remotely control the fire protection robot.
- these fire protection robots comprise a sensor system, for example one or more cameras, which transmit information about the surroundings of the fire protection robot to the user. On the basis of this information, the user then decides how to move / move the fire protection robot and / or which actions the fire protection robot should perform on the way to and at the location of the fire event.
- a disadvantage of this solution is that each of these fire-fighting robots must be controlled by a user.
- Another disadvantage is that the transmission of the information determined by the sensor information about the environment of the fire-fighting robot is prone to failure.
- the objects transmitted to the user for determining the surroundings can become unusable due to smoke development. It is therefore desirable to provide a fire safety robot which does not have these disadvantages.
- the object of the invention is to provide a fire protection robot whose operation and / or control requires reduced user interaction.
