Abstract: An autonomous system for supporting wooden members is presented. The autonomous system includes a mobile robot configured to lift, move, and position robotic jack stands on a working surface. The autonomous system also includes a robotic jack stand with electromagnets operable to demagnetize when the mobile robot lifts the robotic jack stand from the working surface and magnetize when the mobile robot positions the robotic jack stand onto the working surface. The robotic jack stand also includes a vise member with a stationary member and a sliding member. A first motor moves the vise member along an x direction, a pair of motors move the sliding member along an y direction, and a second motor rotates a portion of the robotic jack stand by an angle theta around a z direction. The autonomous system further includes a localization system to determine a spatial location of the robotic jack stand in reference to the x direction, the y direction, and the angle theta.

Abstract: An autonomous system for installing nail plates in wooden structures is provided. The system includes a C-clamp press attached to and be operated by a mobile robot. The C-clamp press includes a hydraulic cylinder operable to move a top plate relative to a stationary bottom plate; a coupler interposed between an end of the hydraulic cylinder and a the top plate; a stationary bottom plate; a top magnetic plate attached to the top plate; and a bottom magnetic plate attached to the bottom plate. Each of the top and bottom magnetic plates are configured to hold a nail plate and to embed the nail plate into a wooden member of a wooden structure when the C-clamp press is operated by the mobile robotic arm. The system further includes a computer vision system and a pressure sensor.
