One thing to take into account is that the prototype was built by canabalizing a 15-20 year old robot arm. The clumsiness/cost would be affected by this to a large degree. Well, perhaps not the cost. Actually, Mark, I think the software for force-feedback would make a spiffy real-time project, don't you? :-) -- Blair MacIntyre, Computer Graphics Lab Dept. of Computer Science, University of Waterloo, Waterloo, ON, Canada, N2L3G1 {bmacintyre@{watcgl|violet|watdragon}}.{waterloo.edu|uwaterloo.ca}
