PCT and Robotics

[From Rick Marken (2017.08.05.1015)]

RM: I think PCT -based roboticists (I’m looking at you Rupert) need to come up with a clear and compelling case for how building robots based on PCT can result in a better robot that these:

RM: These robots are particularly impressive because they are built to deal with unpredictable disturbances. That is, they control perceptual inputs, not motor outputs; they are perceptual control systems. Of course, the builders don’t think of it that way but that what they are. So how does explicitly building robots based on PCT improve things?

Yeah, yeah , yeah :) I've tried to find out what their methodology

is, to no avail. But it must be something similar to PCT.

        RM: These robots are particularly impressive because they

are built to deal with unpredictable disturbances. That is,
they control perceptual inputs, not motor outputs; they are
perceptual control systems. Of course, the builders don’t
think of it that way …

Well, Dag (and Christine) stayed with me last week and Dag left with

me some of Bill’s email threads. One was a brief communication
between Bill and Marc Raibert in 1996. Just saying!

        but that what they are. So how does explicitly building

robots based on PCT improve things?

Perhaps they are lacking the hierarchy?

Btw, fancy getting his book? Only £587!

RM: Well, it’s a little out of my range. But it would be nice if there were some place where there is some nice, clear documentation of his architecture. Is there any hints from his dialog with Bill?
