A technique is described whereby a closed-loop servo logic circuit card is used with a standard master/slave processor and a standard interface bus to provide analog-to-digital and digital-to-analog feedback and control capabilities, so as to enable the system to function as a robot-positioning controller. The circuit is unique in that it provides separate analog power distribution that isolates the high-resolution analog input from standard bus logic noise and uses industry standard bus interfaces. Logic card 10, as shown in the figure, is designed to interface to standard bus 11 for digital logic power and ground only. Communications to processor card 12 is through connector 13. Processor card 12 is a ZT 8830, manufactured by Ziatech Corp. Connectors 14 and 15 on the logic card interface to the drive circuitry of the robot.
