Wiesels were tested quite successfully in secret on the Columbia Icefields
during WWII. There is one at Donner pass at the ski museum. They are
small tracked vehicles. They were developed, quite right, for snow,
and they were used on 1 patrol in WWII in Northern Italy (there is file
footage).
The vehicles developed using the Archimedean screws were developed for a
Swedish version of Wiesels (never successfully sold in the US). I remember
ad for this on TV around 1962. The principal is beautiful and
simple. I was visiting Hans Moravec at CMU in his robotics lab a little more
than a year ago. I surprised him knowing the history of his robot's
"wheels." Many advantages (like moving sideways), and a few disadvantages
(like going straight on roads, too much friction).
Longish signature follows "Type 'n' now"
