A mobile machine tool for processing a surface of a workpiece or of a room having a working device which is mobile with respect to a surface of the workpiece or room, which working device includes a tool receptacle for a work tool driven or drivable by a drive motor and/or a coating device having a coating tool for coating the surface, wherein the working device includes a suction device for suctioning the working device onto the surface by means of at least one force component oriented in a normal direction of the surface, wherein the suction device has at least one valve for controlling an intake air flow and/or a negative pressure in a suction region of the working device for suction onto the surface, and wherein the at least one valve has a valve member which is adjustable between at least two valve positions in which a flow cross-section of the valve is different. The suction device includes a suction controller for adjusting the valve member during operation of the work tool or the coating device between its valve positions depending on at least one physical variable.

A paint trencher includes a main body, a guide, an abrasive body, a first adjustable bracket, a second adjustable bracket, and a handle. The main body includes a top panel, a support, a first pin, and a second pin. The guide is rotatably connected to the first pin and the second pin so that paint trencher can be adjusted according to the ceiling corners or vertical corners. The abrasive body is adjacently mounted to the support, and the handle is mounted to the top panel so that applied pressure of the main body can be transferred into the abrasive body to cut a trench into the wall. The first adjustable bracket and the second adjustable bracket are oppositely positioned of each other about the support and are operatively coupled between the top panel and the guide thus enabling the guide to be adjusted and locked about the main body.

An automated insulation application system that includes a robotic arm and an insulation end effector coupled at a distal end of the robotic arm, the insulation end effector configured to apply insulation material to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the insulation end effector and robotic arm to perform at least one insulation application task that includes applying insulation material via the insulation end effector to a target surface, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one insulation application task.

An automated drywalling system for applying joint compound or plaster to drywall pieces. The system includes a robotic arm and a mudding end effector coupled at a distal end of the robotic arm, the mudding end effector configured to apply joint compound or plaster to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the mudding end effector and robotic arm to perform at least one mudding task that includes applying joint compound or plaster, via the mudding the end effector, to one or more joints between a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one mudding task.

An attachment for a mobile handling device is configured for processing walls or ceilings. The attachment comprises a mounting unit that is arranged to be supported at a mounting interface of the handling device, a processing head that is arranged to be equipped with at least one tool for material-removing processing or smoothing processing, and a compensation arrangement that is arranged between the mounting unit and the processing head and that defines a longitudinal axis. The mounting unit provides at least two pivot positions for the attachment that are offset from one another. The processing head is movable relative to the mounting unit in a longitudinal direction along the longitudinal axis. The compensation arrangement is configured to provide a defined contact pressure force for the processing head in a defined operating range along the longitudinal axis towards the surface to be processed.

A surface repair tool for repairing defects in surfaces includes a handle with an applicator blade extending from one end of the handle and a sanding device extending from the opposite end of the handle. The handle includes a receptacle into which is removably received a container of repair compound. The applicator blade includes an application surface and a flow passage that has an inlet and an orifice formed through the application surface. Squeezing the container causes repair compound in the container to flow through the flow passage of the applicator blade and out of the orifice where it is dispensed onto the applicator surface to be spread on a surface needing repair. Once the repair compound dries, the sanding device is used to sand the repair compound to a desire finish.

An automated sanding system that includes a robotic arm and a sanding end effector coupled at the distal end of the robotic arm, with the sanding end effector configured to sand a target surface. The system can further include a computing device executing a computational planner that generates instructions for driving the sanding end effector and robotic arm to perform at least one sanding task that at least includes the sanding end effector sanding a target surface, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one sanding task.

An automated drywalling system network that include one or more automated drywalling systems that each comprise a robotic arm. The automated drywalling system network can also include one or more drywalling end effectors configured to couple to a distal end of the robotic arms of the one or more automated drywalling systems. The drywalling end effectors can include a drywall hanging end effector; a drywall mudding end effector; a drywalling sanding end effector; and a drywall painting end effector.

A surfacing apparatus supported adjacent a substantially vertical surface of a structure for applying an even and uniform texture to the surface of the structure using a selectively adjustable force exerted on a texturing means to engage the surface of the structure. The surfacing apparatus is suited for horizontal and vertical movement in controlled prescribed paths under controlled and prescribed pressure from the adjustable tensioning means. The surfacing apparatus can include a texturing head that can be configured to conform to the contour of a curved work surface to apply an even and uniform texture thereon.

A system for treating a surface of a structure includes a wheeled vehicle that is movable along a surface and includes at least one surface treatment device.
