          Abstract

          The development of  sensors  for  determining  the  position  and
          orientation of rigid parts by vibrating them and measuring param-
          eters associated with the vibration will be described.   The  aim
          of  the work was to find flexible, economic and reliable means of
          enabling robots to feed themselves with workpieces.

          It is envisaged that, using the sensors, the robots would be able
          to  acquire  parts from stacks or trays.  The initial location of
          the parts does not have to be precisely known and there  will  be
          no  need  for  accurate  jigs  and fixtures and part presentation
          equipment.  On the other hand, parts are  not  completely  disor-
          dered, as they would be in a bin.

          The computation of the exact  co-ordinates  of  the  parts  takes
          place  after  they have been picked up.  As previously mentioned,
          this involves measuring vibration  characteristics  (frequencies,
          speeds,  displacements)  of  the system comprising the sensor and
          the part to be located.

          Different versions of sensors will  be  described.   The  use  of
          Transputers  (microprocessors designed for parallel computing) to
          speed up the sensor's operation will be discussed.

          The talk will be illustrated with a short video.
