Well, actually, I did think :-) I "invented" this some while ago. Didn't design it fully. Never even started to think about actually building one, of course. Which is, in this sort of endeavour, is (part of) what sorts the men from the boys. I had more in mind a "roadable" machine along the lines of a bikies trike but with only two wheels. I have a file where I keep my more notable weird ideas and it didn't even get that far so I can't have thought to much of it. I saw a very short clip on TV tonight and I am suitably impressed. I am not underwhelmed by this - I think it has immense potential, but not necessarily as currently envisaged. Applied to "robots" it gives you something which approximates human mobility in relatively confined spaces and would seem to be far more practical than currently available consumer market "walking" robots (eg Honda's) which cheat rather badly in how they achieve bipedal locomotion. > http://abcnews.go.com/sections/GMA/GoodMorningAmerica/GMA011203What_IT_is.ht > ml > > Anyone else underwhelmed ? > > This was the best bet many months ago in a 60 Minutes program, > so perhaps the guessing-game hype never got to me Note that the hype was from the camp followers and not from the master. He played down the import of his invention while still indicating that it was significant. I think he may be proven correct. How superior it is to a very short wheelbase conventional design is to be seen.
