Wait a minute. You are an academic!

And you admit it. ;)

Yes. That is also part of my interest in the original post. Just
how important are the advances made since 1992? Is it the
hobbiest community is behind the times, or is it that they've
plateaued out at the last break of significance? And the
advances are significant enough to be excited about.

Yes, there is the most current paradigm name I am familiar with,
the Hybrid Architecture. That was the missing name no one had
offered up to this point.

So are we to conclude there has been nothing of value in the
research of the last 15+ years? Or that there are things of
value, just not to a low cost robot? Or there are things of
value but not of note to the hobbiest level user. (The last is
my best guess of the state of things.)

Yes, you make a nice complement to our community. But brother,
you're one of us now. Or at least you've got one foot in each

Very thoughtful post, Brian, thanks for taking the time to
