Device and method for use in cleaning a facade

A system for controlling cleaning of a building facade from a basket of an elevator platform of a building, comprising:

• at least one processor configured to:
• receive a multi-dimensional map of at least a portion of at least one facade of the building;
• determine, according to the multi-dimensional map, an ordered sequence of instructions, comprising:
• robotic arm instructions for controlling at least one robotic arm of a robotic system mounted on a basket of the elevator platform, and
• elevator platform instructions for controlling a position of a basket;
• wherein said robotic arm instructions and said elevator platform instructions are temporally intertwined to execute a cleaning pattern covering at least part of the at least one facade along a plurality of different floors;
• forward said robotic arm instructions to the robotic system for controlling the robotic arm of the robotic system via a first interface;
• and
• forward said elevator platform instructions to a building maintenance elevator component for controlling the elevation of the basket via a second interface which is different from the first interface;
• wherein said at least one first interface comprises a first electromechanical interface of a processing component comprised in a control system of the robotic system and adapted for communicating with the at least one robotic arm via said first electromechanical interface to drive movement of said at least one robotic arm,
• wherein the second interface is a communication interface comprised in a control system of the building maintenance elevator which is separate from the control system of the robotic system and adapted for communicating with a remote device to receive said elevator platform instructions, wherein the control system of the building maintenance elevator comprises an output to a second electromechanical interface that drives movement of the elevator platform.

A non-transient computer readable medium instructions for execution of a program for controlling cleaning of a building facade from an elevator platform of an elevator system, wherein execution of the instructions by at least one processor configures the processor to:

• receive a multi-dimensional map, generated from sensory data having at least three dimensions, of at least a portion of at least one facade of the building;
• determine, according to the multi-dimensional map, an ordered sequence of instructions, comprising:
• robotic arm instructions for controlling at least one robotic arm of a robotic system mounted on a basket of an elevator platform of the building, and
• elevator platform instructions for controlling a position of the basket;
• wherein said robotic arm instructions and said elevator platform instructions are temporally intertwined to execute a cleaning pattern covering at least part of the at least one facade along a plurality of different floors, thereby motions of the at least one robotic arm and basket according to said robotic arm instructions and said elevator platform instructions are simultaneous at least in part throughout time;
• forward said robotic arm instructions to the robotic system for controlling the at least one robotic arm of the robotic system via at least one first interface;
• and
• forward said elevator platform instructions to a building maintenance elevator component for controlling the elevation of the basket via a second interface which is different from the at least one first interface;
• wherein said at least one first interface comprises a first electromechanical interface of a processing component comprised in a control system of the robotic system and adapted for communicating with the at least one robotic arm via said first electromechanical interface to drive movement of said at least one robotic arm,
• wherein the second interface is a communication interface comprised in a control system of the building maintenance elevator which is separate from the control system of the robotic system and adapted for communicating with a remote device to receive said elevator platform instructions, wherein the control system of the building maintenance elevator comprises an output to a second electromechanical interface that drives movement of the elevator platform.
