From Greg Williams (930121)
Regarding the ongoing discussion about modeling pointing behavior,
I think it is clear that PCTers apparently could be looked up to
by (at least some) roboticists if they successfully make a fast
PCT model (endpoint control) with six or seven degrees of freedom.
So, if that's what it takes, why not try to do it? I say: go to
it, Bill! Even if the attempt fails, it will be instructive to
all. But I don't think it will fail.
As ever,
Greg
