Abstract: This paper presents an open embedded hardware and software architecture for industrial robot control applied to visual servoing system. This architecture is a hardware and software co-design where embedded processors drive the FPGA for motor control. It is robot type independent, as long as the motors are equipped with incremental position encoders and driven by PWM signals. Low cost, low power consumption, high stability, flexibility and expandability are the key advantages. The architecture and related IP cores are developed through a component-based design model which interprets a mechatronic system by computation, communication, configuration and coordination components, together with composition of these components and blackboxes. The motor controller IP core is provided in the consistency of open hardware. Open software implies the use of OROCOS (Bruyninckx, 2001). The performance of visual servoing behaviour is evaluated by visual coupling of a Performer MK2 robot and a KUKA lightweight robot.
