A tool guide has a mounting, a lifting mechanism, and a chassis. The mounting is for fixing a hand-held machine tool. The mounting is mounted on the lifting mechanism. The lifting mechanism has a propulsion unit for vertically lifting the mounting. The chassis has two wheels on a wheel axle, a drive coupled with the wheels, and a steering system. The lifting mechanism is rigidly mounted on the chassis. A center of gravity sensor is arranged to detect a lateral deflection of the center of gravity of the lifting mechanism relative to the wheel axle. The steering system is configured to control the drive to deliver a torque counteracting the lateral deflection.

A vertical inverted drill press apparatus configured to extend a drill about a vertical support having a top portion and a bottom portion. The top portion is configured to telescope out and away from the bottom portion when manipulated via a lever. The lever pivots about a pivot point. The lever amounts to a handle disposed in communication with an actuator which manipulates a swing arm. The swing arm is connected to the telescoping top portion. When the handle is pulled down, the top portion is forced upwards in a straight line along the primary axis of the body. A drill mount is configured to secure a drill in an inverted, drill-bit-up orientation to facilitate the drilling of holes in ceilings and similar locations.

An elongated tool support device, which is used to support an elongated tool, includes a securing tool, a first shaft support, a brace member, and a second shaft support. The first shaft support is configured to support a shaft portion of the elongated tool from below. The brace member is disposed between the securing tool and the first shaft support. The second shaft support is attached to the brace member and configured to support the shaft portion of the elongated tool from above.

A portable work bench that is configured to be transitioned from a folded position to a deployed position. The portable work bench of the present invention includes a frame wherein the frame includes a first set of vertical support members and a second set of vertical support members. A pair of opposing upper support members are superposed the first vertical support members and second vertical support members. A work bench surface member is secured to the upper support members. The work bench surface member further includes a pair of opposing board support members on opposing ends thereof. The portable work bench includes a first set of extension members and a second set of extension members extending outward from opposing side of the frame. The first set of extension members second set of extension members each have a void operable to have releasably secured therein a receptacle.

A method of operating a mobile construction robot includes placing an optical tracker on an architectural construction site and parking a driving platform of the robot on the site. An end effector of the robot is moved in first and second positions and the first and second positions of the end effector relative to the driving platform are measured. An optical marker mounted to the end effector is tracked in the first and second positions of the end effector with the optical tracker and the first and second positions of the optical marker relative to the optical tracker is measured with the optical tracker. A position and an orientation of the driving platform is determined based on the measured first and second position of the end effector relative to the driving platform and the measured first and second position of the optical marker relative to the optical tracker.

The Overhead Drill and Anchor Press is a single mobile mechanism designed for installation of anchors into a construction surface which is overhead and out of reach of the installer. The overhead drill and anchor press may include a mast, a turret assembly, a controller, and at least one drill. The overhead drill and anchor press can execute the anchor installation sequence automatically or manually with a controller by moving the drill position to drill the hole and set the anchor. The controller may be equipped with a digital display of the turret mounted camera for monitoring the process from the ground. The entire assembly may be manually pushed between target.

A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis, a drive coupled to the two wheels, and a steering system. A contact sensor serves for detecting an indirect contact of the holder with the ceiling. The chassis has a brake. A controller has a mode in which the brake is activated and the balancing of the self-balancing chassis is deactivated.

A drill assist device comprising a first segment and a second segment telescopically coupled to one another, where the first segment further contains a gas strut. A pull down handle is configured to connect the first segment and the second segment and enable compression of the drill assist device when a worker applies pressure to the pull down handle. This compression is further assisted by at least one wire rope cable that is affixed to both the pull down handle and the second segment and may be secured via one or more wire rope clamps. The wire rope claims maybe tightened or released to extend or retract the second segment to achieve the desired height of the drill assist device.

A high reaching pruning apparatus is provided. The high reaching pruning apparatus has an elongated telescoping pole, a foot brace and a hook for grasping a tree limb. The high reaching pruning apparatus is suitable for easily pruning and trimming tall trees.

A construction robot for a ceiling is provided. The construction robot includes: a robot base having an upper plate; a targeting unit on the upper plate, wherein the targeting unit moves a robotic arm assembly combined with the targeting unit, and wherein the robotic arm assembly includes: a first robotic arm where a drill is mounted, wherein a first elevating unit of the first robotic arm is elevated or lowered according to information on the ceiling, a second robotic arm where an anchor bolt inserting equipment is mounted, wherein a second elevating unit of the second robotic arm is elevated or lowered according to the information, and a third robotic arm where an impact wrench is mounted, wherein a third elevating unit of the third robotic arm is elevated or lowered likewise; and a loading unit on the upper plate or the targeting unit for providing anchor bolt assemblies.
