In particular embodiments, a sheetrock robot may be an autonomous (or semi-autonomous) system comprising a drive base, lift assembly, load Manipulator, and screw gun assembly. In particular embodiments, the sheetrock robot's functions may include, for example: (1) taking a piece of sheetrock off of a stack; (2) picking it up and transporting it to a desired location; (3) lifting and manipulating it into position using the load manipulator; (4) detecting studs; and (5) attaching it to a studded wall with sheetrock screws.

A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

A preferred embodiment of the present invention is directed to a rotary tool and, more specifically, to a pneumatic wrench that can be used as both a standard socket wrench and as a fastening tool for setting HI-LOK-type fasteners commonly used in the aviation industry. In a preferred embodiment, the wrench comprises a handle and a rotational member connected to the handle, said rotational member configured for exerting torque about an axis of rotation in one direction only. The wrench further comprises a hole extending through the rotational member along the axis of rotation. The hole has two ends each having female threads. One end has right-hand threads and the second end has left-hand threads. The tool further comprises socket adaptors having right-hand and left-hand male threads for attaching the adaptors to the wrench. Each socket adaptor also has a through hole that aligns with the hole in the rotational member. The holes allow a hex key to be inserted through the wrench so that the wrench can be used to fasten HI-LOK fasteners. The simple design of the tool results in a wrench that is easy to use and relatively inexpensive to manufacture. A preferred embodiment of the invention further comprises a method of using the wrench.

A device for screwing and unscrewing bolts and screws uses a motor-driven screwdriving tool, which is preferably used in the track region of railroad facilities. The device makes it possible to screw and unscrew screws, nuts and bolts reliably and effectively, preferably in the context of railroad use. The appliance is intended to have a low weight and a high output over long periods of use, can be operated with one hand, is specifically pre-oriented to the various applications and has a modular construction. To this end, the device has a central rib which serves as a receptacle for all of the attachments and fittings to be installed in a modular manner.

A tool for sealing a workpiece, the workpiece comprising a first component and a second component sharing a rotation axis A, the tool comprising: a fastening head capable of engaging the first component; a first motor operationally coupled to the fastening head; a controller capable of: storing a rotation value representing rotation of the first component a predetermined desired angle around axis A; measuring movement of the first component, and controlling movement of the first motor; the tool, when the fastening head is engaged with the first component, and the second component is essentially immobilized from rotation around axis A, is configured to allow precisely sealing the workpiece by: rotating the first component in a closing direction R toward the second component, according to the rotation value and under the control of the rotation by the controller.

A uniquely designed torque wrench having a torque body, the torque body attached to a frictional squeezing clamp, and a lug socket which is rotationally connected to the frictional squeezing clamp. The frictional squeezing clamp entering a contracted stated during extension of a rod of a hydraulic cylinder, and entering an expanded state during the retraction of the rod of a hydraulic cylinder, the lug socket turning the wing nut of a hammer union.

A door stop installation device. The door stop installation device may include a main body portion; a door stop receiving portion integrated into the main body portion; an extension portion extending from a proximal end of the main body portion; an opening in a distal end of the main body portion; and wherein, the door stop receiving portion may be configured to receive at least one type of a door stop.

A rotary-drive sub-assembly includes a tool and a tool retainer. The tool includes a fastener-engagement portion, a first threaded portion, and a tool-change-engagement portion between the fastener-engagement portion and the first threaded portion. The tool retainer includes a body and a retaining member. The body includes a symmetry axis, a second threaded portion, configured to be threadably fastened with the first threaded portion of the tool so that the tool is rotationally anchored relative to the body of the tool retainer about the symmetry axis and is translationally anchored relative to the body of the tool retainer along the symmetry axis, and a key, fixed relative to the second threaded portion. The tool retainer further includes a retaining member that is removably coupled to the body at a fixed location.

An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.
