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.

Abstract: Systems and methods for a fastener driving system are disclosed. The system includes a fastener driving tool configured to drive a fastener through a covering material and into an underlying framing member, where the fastener tool generates sound upon driving the fastener through the covering material. The system includes an acoustic transducer configured to capture the sound generated by the fastener driving tool. The system includes processing circuitry configured to analyze a frequency spectrum of the audio to generate a frequency spectrum analysis, based on the frequency spectrum analysis, determine whether the fastener hit or missed the underlying framing member, and generate an indication of the determination.

The robotic automated framing system can also schedule a robot to perform the project, and cause the robot to perform at least some of the project.

Abstract: Faster, less computational intense, and more robust techniques to optimize velocity of robots or portions thereof without violating constraints on acceleration and jerk (derivative of acceleration with respect to time) are described. A nonlinear problem of optimizing velocity without violating acceleration constraints is linearized, and produces acceleration constrained velocity estimates. A nonlinear problem of optimizing velocity without violating jerk constraints in linearized, and produces jerk constrained velocity estimates, and may be feed by the acceleration constrained velocity estimates. Configuration and timing may be generated and provided, e.g., as vectors, to control operation of a robot, robotic appendage or other structure.
