Work Table

The main scope of this work is the development of a robot controller for the manipulation of fabrics lying on a work table towards the sewing process. A fuzzy visual servoing manipulator controller is developed to guide the fabric along the sewing line. The paper focuses on handling fabrics with curved edges by locally approximating the curve section with straight-line segments. An innovative algorithm based on the dominant point detection method and the genetic-based method is incorporated in the robot visual servoing system to achieve sewing of the curved edges. Simulation and experimental tests are conducted to evaluate the performance of the proposed algorithm. The results demonstrate that this approach is efficient and effective for the polygonal approximation, and the proposed robotic system is proved to be robust and efficient, achieving acceptable seam accuracy in the minimum time.

An acupuncture point detection technique is described in which the needle to be used in therapy acts as a guide for the point detection. The needle is dabbed tangentially onto the area around the point until a loss of resistance is felt and the patient reports an electrical sensation. This method can be used particularly well in two areas of the hand: along the outer edges of the thumb and little finger. These partial acupuncture microsystems are described with therapeutic indications for their points.
