  • Saddle-shaped trajectory generator for two intersecting pipes
    Patent number: 8536817
    Abstract: An apparatus for generating a saddle-shaped trajectory for intersection of two cylindrical conduits. The apparatus includes an encoder module, a motorized axial module connected with the encoder module and movable only in a direction parallel to a longitudinal axis of an intersecting cylindrical conduit and a motorized rotatable module connected with the motorized axial module and rotatable around the longitudinal axis of the intersecting cylindrical conduit. Control software provided in one of the modules includes an algorithm providing control of the modules for generation of the saddle-shaped trajectory on the two cylindrical conduits. The algorithm requires input of only a radius of each of the cylindrical conduits.
