This disclosure relates to system and method for cleaning surfaces using drones. The method includes identifying, by a first drone, a cleaning strip in contact with a surface. The cleaning strip connects a second drone and a third drone. The second drone is communicatively coupled with the third drone. The first drone is communicatively coupled with each of the second drone and the third drone. The method further includes releasing a cleaning agent at a preconfigured pressure upon a current target region of the surface near the cleaning strip. The method further includes relocating the cleaning strip upon the current target region. The method further includes performing a set of oscillations through the cleaning strip across the current target region. Each of the set of oscillations includes coordinating a displacement of the cleaning strip by a predefined distance, alternating towards each of ends of the cleaning strip.

A frame body may be parallel to and proximate with an external surface of a structure and extend substantially horizontally from a first side to a second side. A connecting portion may be provided to be attached to a cable to provide for vertical movement of the frame body. A robotic arm may be affixed proximate to a bottom of the frame body and be able to move horizontally during treatment of the external surface. Moreover, the robotic arm may extend to an end proximate with the external surface, and a cleaning portion may be attached to the robotic arm near the end proximate with the external surface. The robotic arm may rotate, vertically moving the cleaning portion during treatment of the external surface. In addition, the cleaning portion may be separately rotated to remain substantially parallel to and proximate with the external surface during rotation of the robotic arm.

A mobile panel maintenance system including a mobile panel maintenance unit having a base supported for translational motion over a surface within a panel array and a carriage movably mounted to the base to position a panel maintenance assembly in relation to a panel surface for panel maintenance.

A system for sanitizing and controlling people who want to access a room (40), adapted to at least reduce the risk that people can bring pathogenic contaminants into said room (40), in particular viral pathogenic contaminants, such as for example coronavirus,

comprising: a sanitizing cabin (1) having a size such that it can house at least one person inside; a sanitizing unit (7) for sanitizing the person present inside said cabin, and at least one controller (12) which is operatively connected to a sanitation activating element (32, 36, 100E), said controller (12) being configured to determine a process control command for said sanitizing unit (7) to supply a sanitizing substance to said cabin for a predetermined time, when it receives at least one activation signal from said sanitation activating element (32, 36, 100E).

Disclosed is a method for controlling cleaning at least a portion of a building facade (104a). A multi-dimensional map of a facade (104a) is cleaned from an elevator platform (200) of an elevator system is received. According to the map, an ordered sequence of instructions is determined. The instructions comprise robotic arm instructions and elevator platform instructions that are temporally intertwined to execute a cleaning pattern covering at least part of facade (104a). The robotic arm instructions are forwarded to control one or more robotic arms (206) and the elevator platform instructions are forwarded to control the elevation of the elevator platform (200). A corresponding device (221, 213) and non-transient memory (223), and a system having the device, are also disclosed.

A robot includes: a robot body including a plurality of joints, and a cleaning mechanism provided to the robot body and configured to clean a predetermined cleaning target site of the robot body to which a foreign material is likely to adhere.
