An automated drywalling system for cutting and/or hanging drywall that includes one or more vision systems and a computing device executing a computational planner. The computational planner obtains target wall assembly data from the one or more vision systems, the target wall assembly data including information regarding a configuration of a target wall assembly including a plurality of studs that define a portion of the target wall assembly; and generates a plan for a configuration of a plurality of drywall pieces to be disposed on studs of the target wall assembly based on the target wall assembly data.

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.

An automated drywalling system network that including one or more automated drywalling systems that each has a robotic arm. The automated drywalling system network can also include a computational planner that generates instructions for the one or more automated drywalling systems to perform two or more drywalling tasks associated with a target wall assembly. The two or more drywalling tasks can include a hanging task that includes hanging pieces of drywall on studs of the target wall assembly; a mudding task that includes applying joint compound to pieces of drywall hung on studs of the target wall assembly; a sanding task that includes sanding joint compound applied to the pieces of drywall hung on studs of the target wall assembly; and a painting task that includes painting sanded the joint compound applied to the pieces of drywall hung on studs of the target wall assembly.

In order to provide a handheld abrading machine which has a simple, efficient and as fatigue-free an abrading action as possible and which includes a holding device for holding the abrading machine, a drive motor and a tool head, wherein the holding device includes a substantially tubular bar that has a proximal end and a distal end, wherein the drive motor is arranged at the proximal end, wherein the tool head is arranged at the distal end, wherein the abrading machine includes a transmission shaft which connects the drive motor to a tool holder of the tool head for transmitting torque thereto and which runs at least in sections thereof within the tubular bar, it is proposed that a motor shaft rotational axis of the drive motor be oriented transversely, and in particular inclined, relative to a longitudinal axis of the tubular bar.

A flatness control structure for a drywall sander, comprising: a device body, wherein the bottom of the device body is equipped with a rotating device, a housing is arranged below the device body, a sanding component is arranged inside the housing, the sanding component comprises a sanding piece, the bottom of sanding piece is connected to a sanding disc, and the bottom of sanding disc is connected to sandpaper, a threaded bolt is arranged between the sanding piece and the housing, a fixing component is arranged inside the housing, and an installation component is arranged inside the housing. The sander replaces the bristle sections with a wear-resistant strip which is less likely to deform when in contact with the sanding surface. When force is applied, the sander can be firmly fixed on the sanding surface, ensuring stability of the entire sander, thereby improving the flatness of the sanding surface.

A sanding apparatus for sanding a vicinity of a drywall seam is provided comprising a housing structure including guide structures, a sanding roller, and a motor for driving the sanding roller such that the guide structures guide a sanding depth during sanding. The sanding apparatus further includes a vacuuming mechanism for capturing particles that result from sanding.

Support systems and apparatus that can be used to support maintenance systems usable on the internal side of the sidewall of external floating roof tanks are provided. The support systems can include at least one stanchion that is mounted on a carriage for moving the maintenance system around the sidewall of an external floating roof tank and two or more internal wall contact stabilizers that are adjustably positioned relative to the carriage for aligning the system in place.

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.
