1. A patching robot comprising:
- a base portion comprising at least one motorized wheel disposed adjacent a lower end of the base portion;
a multi-axis robot arm;
a vertically adjustable platform disposed adjacent an upper portion of the base portion;
a raisable shroud disposed about a perimeter of the vertically adjustable platform, the raisable shroud comprising a curtain that is configured to raise between;
a lowered position adjacent the platform; and
a raised position that encompasses a work area of the multi-axis robot arm when in the raised position;
means to mount the arm on the platform; and
an arm controller operationally connected to the arm.

Abstract
A concrete patching robot has a multi-axis robotic manipulator mounted on a powered, movable, platform that can be raised and lowered to access the underside of structures that may be substantial distances above the ground, for example, the underside of an elevated highway. The entire assembly is maneuverable under the work area and the platform may be raised to access the concrete. Once the work area is in reach of the arm, the device is able to use numerous tools to complete essential steps to repair the concrete.

12. A concrete patching robot for patching a cavity in concrete, the concrete patching robot comprising:
-
a base portion comprising at least one motorized wheel disposed adjacent a lower end of the base portion; a vertically adjustable platform disposed adjacent an upper portion of the base portion; a lifting mechanism coupled to the vertically adjustable platform; a multi-axis robot arm disposed on the platform; a raisable shroud disposed about a perimeter of the vertically adjustable platform, the raisable shroud comprising a curtain that is configured to raise between; a lowered position adjacent the platform; and a raised position that encompasses a work area of the multi-axis robot arm when in the raised position; a drill tool configured to drill one or more holes in the cavity; an anchor placer tool configured to insert an anchor in each of the one or more holes; a grout fill tool configured to fill the cavity with grout; and a computer controller configured to; cause the lifting mechanism to lift the vertically adjustable platform such that the robot arm is positioned adjacent the cavity; cause the raisable shroud to raise to the raised position; cause the drill tool to drill the one or more holes in the cavity; cause the anchor placer tool to insert an anchor in each of the one or more holes; and cause the grout fill tool to fill the cavity with grout.
