  • Publication number: 20230219240
    Abstract: A clamp for a robotic drill and related method and system for robotic drilling of a component. The clamp attaches to a drilling tool of a robotic drill. The clamp includes: an attachment portion configured for attachment to the drilling tool; a frame linearly moveable relative to the attachment portion along a central axis of the clamp parallel to a drilling direction of the drilling tool; an actuation mechanism including a servo motor configured to drive linear movement of the frame relative to the drilling tool; a workpiece contacting portion at a distal end of the frame, including a surface for contacting a surface of a workpiece to be drilled and an aperture allowing for passage of a drill bit of the drilling tool through to the workpiece surface; and a force sensor arranged to measure a force acting on the workpiece contacting portion in the drilling direction.

  • Patent number: 7813830
    Abstract: A drilling machine drills at a multiplicity of target locations on a component. Two robots, calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system ascertains the position of the component relative to the drilling machine. The movement of the robots is effected by commands generated by off-line programming. The component is moved relative to the drilling machine to a target position, ready for drilling, by a closed-loop process in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected.

  • Publication number: 20060140288
    Abstract: Apparatus and method for transmitting information, utilizing a multicarrier waveform containing the information. The waveform presents symmetrically-shaped first and second sequential portions which are substantially equal in length. All subcarriers are restricted in phase values to 0 and ?, or alternatively, ?/2 and 3?/2. One, but not both, of the portions is transmitted to a receiver. The transmitted portion is duplicated and the duplicated portion is than reversed. The duplicated portion is also inverted in the case where the phase values are restricted to 0 and ?. The duplicated, processed portion is then sequentially combined with the originally transmitted portion to reform substantially the original waveform. Thus the invention dramatically reduces the length of the waveform to be transmitted, thereby increasing transmission and reception rates while minimizing the number of calculations required.
