I like your remark about 'feedforward' -- which really doesn't fit my
views of the way control systems work.

"anticipation" seems to refer to a widely recognized concept, that
does fit my views of the way control systems work.

I find the concept of "memory" very useful in this type of situation.
Memory, used in this manner, also seems to be widely recognized --
although rarely included explicitly in discussions I see on the net.

To me, it is pretty straightforward and familiar to perceive, from
memory, past experiences of bicycles and bumps -- followed by using
the memory as a guide in selecting a combination of actions to avoid
repeating an unpleasant experience. I think that most people would
accept this view as consistent with their own experiences -- although
they would not ordinarily bother about reporting these internal
details.

Regards, Bob Clark

Maybe the mechanism would be something like controlling for not-being-about-
to-experience-a-bump, with the perception of `about-to-experience-a-bump'
getting higher as the approaching curb gets closer, until its reference
level is exceeded, and the bum is raised to bring it down again. This
presupposes some reasonably clever `forward chaining' predictive machinery.
