Date: 1 Feb 86 06:52:48 GMT From: ucdavis!lll-crg!seismo!cmcl2!lanl!jlg@ucbvax.berkeley.edu Organization: Los Alamos National Laboratory I keep fairly close tabs on AI and robotics. There is no way with today's technology to build an automaton that could have repaired the Solar MAX satellite. Much less - capture and return disabled satellites. Teleoperation doesn't help this much, the problem is at least partly one of dexterity. I'm working on a project that attempts to duplicate the dexterity of a human hand, and you might be surprised at what has already been achieved. The hand, a joint project between the University of Utah and the MIT Artificial Intelligence Lab, has 3 fingers and an opposing thumb. Each finger has 4 degrees of freedom, giving the hand a total of 16 joints. Soon it should be equipped with a large number of tactile sensors, giving it a primitive (compared with humans) sense of touch. While we still have a while to go before a device like the Utah/MIT hand could be used to repair a satellite, the time is not so far in the future. And if a billions dollars (half the cost of a shuttle) where put into the project, I'd guess that a dexterous teleoperator version could be built in a handful of years. -Dave

Given the current state of the art, 3-4 years minimum to produce a functional prototype that is designed for orbital operation. Of course, you need the shuttle + 2-3 mission specialist to do the debugging and at least two shuttle missions to debug the thing (I am an incurable optimist) How do you retrieve the teleoperator and return it to earth for repair? It is a mechanical device - it will break, more often than planned. How do you return the non-repairable items? This list does go on. At some point it becomes more cost effective to add the mission speciallist. The point is, the two systems are complementary. Having good teleoperator capability without shuttle technology (some form - orient express, ???) only solves part of the problem. We need good teleoperator/robot technology and a good shuttle system.
