The existing machine vision technology is comprised of a proprietary vision system (processor, frame grabber, and software), a lighting system, a laser diode, and a camera / lens combination. Currently, because of technology limitations the vision system can only map (locate and identify) one (1) fastener per image capture, thereby necessitating robot moves to each and every fastener location on the panel. Extensive error handling by the operator is also required. By implementing the state of the art, commercially available hardware and software solution recommended by the ESD team, the mapping capacity will be increased to four to six (4-6) fasteners per move and virtually eliminate the need for the operator to intervene in mapping process.

The ESD team’s recommendation to implement state-of-the-art, commercially available motors and drives will provide years of reliability and enhanced sustainability. Presently the proprietary robot control software environment is limited in its ability to provide for easy code modifications, technology updates, as well as restricting the level of compatible processing equipment. With the implementation of a PLC based control system as recommended by the ESD team, the manufacturer of the control technology is responsible for continuous cycle product updates (both hardware and software), and code modifications can be performed quickly and easily. HPI System Analysis Model/ADF System Analysis Model To ensure that a comprehensive review of the AARS and RMRS workcells was performed, the ESD team divided the upgrade study effort into three focus areas: machine vision, robot control software, and robot hardware.
