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 taping tool is provided, the taping tool includes a housing, a spool disposed at one end of the housing, and a blade disposed at another end of the housing. The blade has a first end defining a first cutting tool and a second end defining a second cutting tool. The blade is retained by the housing in either a first configuration in which the first cutting tool projects from the housing or in a second configuration in which the second cutting tool projects from the housing.

A utility knife is provided for supporting a blade in use, the blade defining a cutting edge, the utility knife including a handle portion, a blade holder positioned proximate the handle and defining a longitudinal axis, the blade holder configured for retaining a blade, and a fastener for selectively retaining the blade within the blade holder in a plurality of orientations. In a first orientation the cutting edge extends substantially parallel to the longitudinal axis of the blade holder, and in a second orientation the cutting edge of the blade extends transverse to the longitudinal axis of the blade holder.

A system for finishing surfaces with a finishing material includes a handle assembly with proximal and distal ends. A material reservoir is mounted on the handle distal and includes an inlet and an outlet. A material applicator tool is mounted on the reservoir and receives material from the reservoir outlet. A discharge mechanism includes an extendable-retractable component or linear actuator connected to the reservoir for discharging or reloading material. An alternative embodiment includes a lockable, compressible gas spring. Another alternative embodiment includes a rotating element driven by a reversible motor mounted on the handle assembly. The rotating element drives a discharge mechanism in a discharge direction of rotation, and reloads the reservoir in a reload direction of rotation. Multiple alternative embodiments of linear actuators are disclosed. An alternative embodiment includes a push-to-open valve mechanism.

A hand tool is provided for the application of joint compound on wall board, a planar blade affixed to a handle. The blade has a concave arcuate working edge, wherein the concave arcuate curve extends the entire length of the working edge to each corner of the working edge. The concave arcuate working edge to may be used to apply a self-featured layer joint compound over drywall tape on planar butt joint or an inside corner joint. The blade is laterally flexible.

In particular embodiments, an on-site drywall fabrication system is configured to perform on-site construction of drywall (e.g., plasterboard, wallboard, gypsum panel, sheet rock, gypsum board, etc.) over at least a portion of a framed (e.g., studded) wall (e.g., comprising one or more substantially vertical studs). In particular embodiments, the on-site drywall fabrication system is configured to utilize one or more drywall installation robots to fabricate drywall substantially directly on a framed wall. Generally speaking, the on-site drywall fabrication system may be configured to generate a substantially continuous, seamless drywall panel that extends along a particular portion of a wall. The system may, for example, utilize one or more sprayers that are configured to spray a suitable fill material between a first wall material (e.g., a first wall material applied via the first wall material spool) and a second wall material.

An automated drywalling system having a computing device executing a computational planner that generates, before hanging any of a plurality of drywall pieces, a plan for a configuration of a plurality of cut pieces of drywall to be disposed on studs of a target wall assembly including a plurality of seams respectively defined by adjoining edges of different pairs of drywall pieces of the plurality of cut pieces of drywall, the plan for the configuration generated based at least in part on an optimization of the plurality of cut pieces of drywall.

A prefill tool for finishing wallboard joints is provided for finishing a wallboard joint, and includes a box assembly defining a hopper, having a top wall and a front wall constructed and arranged for engaging the wallboard joint. The front wall partially defines a gate dimensioned for dispensing joint compound stored in the hopper. Also, the gate is located on a skid plate mounted on the front wall, the skid plate having a main portion, and a gate portion partially defining the gate being displaced from a plane defined by the main portion.

The present disclosure provides for a reversible and adjustable stopper assembly comprised of an upper frame, L-bracket, connector portion and stopping member. The stopper can be configured to be secured to at least two main types of press brakes. The stopping portion of the stopper is also reversible, allowing for less sheet metal to be inserted into the press brake, if desired. The stopper assembly can be slid in a horizontal manner, relative to the press brake to preserve the measurement of the sheet metal from one end of the press brake to the other.

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.
