ABSTRACT:
A method of determining the current orientation of the wrist output of a closed-loop robot wrist having at least one actuator, where the actuator has a displacement sensor, includes generating a look-up table having table orientation data corresponding to the orientation of the wrist output for specific table displacement values of the displacements of the actuator. The method generates displacement signals representative of the displacement of said actuator; selects from the look-up table a set of table orientation data as determined from the displacement signals; and determines the current orientation of the wrist output from that set of table orientation data. Analysis of an equivalent open-loop mechanical model of at least one link of the closed-loop wrist may be used to generate the look-up table.
