Grooved insert plate set in flange.  This insert plate would be incorporated into the flange design so a separate plate would not be required.  This is the suggested design instead of the three pin design.

Initial Measurements

Two separate sets of measurements have been made on the Wonder Wyler unit.  The first set were collected for Alec Robertson's presentation of the device to BMW in Germany.  This data consists of repeated angular measurements of the first unit at each location on the robot.  These measurements show the repeatability of the procedure.  

Initial Accuracy Tests 2001-01-30.xls

The second set of measurements were collected by Pat Willoughby and Alec Robertson during the February 2001 trip to Sweden.  This data consists of measurements using the Leica laser tracking system.  Measurement points consist of the center points of each tooling ball and the coupling triangle for the balls not engaged with grooves.
