Robotic apparatus with improved positioning accuracy
First Claim
1. In a robotic apparatus which includes a primary robot provided with a manipulator means to support and displace a holder, a locating sensor to detect the relative position of said holder, the improvement comprisinga secondary robot mounted on said manipulator means and supporting said holder, said secondary robot separately adapted to move said holder through at least five degrees of movement in response to output from said locating sensor,a mounting plate,a first stage platform movably supported on said mounting plate, a first means to support and rotate said first stage platform relative to said mounting plate about a translational axis X and also move said first stage platform longitudinally in the X direction,a second stage platform movably supported on said first stage platform, a second means to support and rotate said second stage platform relative to said first stage platform about a translational axis Y and also move said second stage platform longitudinally in the Y direction,a third stage platform movably supported on said second stage platform, a third means to support and move said third stage platform in a Z direction relative to said second stage platformsaid locating sensor providing input to control movement of said first stage platform, said second stage platform, and said third stage platform to provide a precise positioning of said holder.
