A Modular Real-Time Fieldbus Architecture for Mobile Robotic Platforms

“…It is widely adopted by numerous commercial field devices and many off-the-shelf interfacing board and component alternatives are available to the designers of instrumentation systems. As a result of this wide adoption, significant research effort has also been devoted to its realtime applications, characterizing and improving predictability of communications [24], [25] and the impact of delays on closed-loop control [26]. Unfortunately, size, power, and weight constraints associated with the design of autonomous mobile robots are much more severe and limiting than those associated with domains in which existing large-scale fieldbus alternatives are intended to be used.…”
