The advantage of distributed processing is that you can take a sometimes considerable load off the main MCU. Consider a speed regulator: a sensor is needed to continuously monitor the speed at which the wheels are turning and adjustments in motor output are necessary to compensate for changes in load/slip/terrain etc. It would be so much easier to just have the RCX tell a sub-processor what speed is desired and have the slave unit count rotations per unit time and adjust the speed accordingly. Of course, with only three inputs and three outputs and a IR port, there isn't a lot for the RCX to do anyway, so in this case it probably won't help a lot. For more complex systems, this is almost essential. Matthias Jetleb VA3-MWJ

		Re: Is there a benefit in delegating processing tasks?
Thanks for the insight, I am sorry that I did not mention the main controller would be a Handyboard (implied though due to the news group). This is still a good point and has given me a lot to think about. The slave controller would continue until (...) (23 years ago, 16-Feb-01, to lugnet.robotics.handyboard)

		Is there a benefit in delegating processing tasks?
I have noticed low cost PICs (such as OOPic) that are capable of controlling (and getting useful data out of) devices like the Polaroid sonar rangefinder and other devices. Is there a benefit in delegating processing tasks such as this to a (...) (23 years ago, 16-Feb-01, to lugnet.robotics.handyboard)
