On robots, however, we seem to like to stall our motors with all the pushing (since nobody has designed a true CVT, yet), so I guess this could be considered a bad thing.
Actually, 190 had a toroidal CVT in 2002, and was planning to use it again in 2003, but it had to be left out due to weight and time considerations. Also, I heard that 222 had a CVT designed and built this past year, but their robot design didn't need it. The hard part with a CVT is not the actual design and build, it's the programming. There is a fine balance between not reacting fast enough and occilating wildly that is very hard to overcome.

There is a good description of toroidal CVTs at http://www.barloworld-cvt.com/varibo...based_cvt.html
