I think you're a very scary man, Kevin.
That walker is absolutely *brilliant*. I don't normally
check out the .technic or .robotics side of things, but
today I'm very glad I did. That is absolutely incredible--
and not least of the achievements is keeping it looking so
very nice. The design is very sound--how robust is it?
Have you tried getting it to bear a load on its back (as
the triangular foot groups and internal center of gravity
might allow)? It seems like it would be very sure-footed
generally. How does it handle inclines or obstacles?
Just wow. Wow.
all best
