[long argument for getting around the time-lag and AI problems of a Mars rover by slowing it down deleted] Fine, the rover is creeping along at the feet feet per hour that you suggest is safe. Now something unexpected happens. The surface shifts. (loose rocks hidden by dust, a dust pocket, whatever] The rover *must* make a real time response. If it isn't autonomous, it can't. You can handle some things be designing in recovery gear (like those levers for righting it that you mentioned) but the odds are against you. What do you do it it manages to "high center" itself? or if it is traversing a slope and starts to slip? I'll agree that your rover will work on Mars the day after it has operated for a year with only a time delayed radio link for support in Antarica.... (if it wasn't for rain and floods, I'd have suggested a desert) -- Leonard Erickson ...!tektronix!reed!percival!bucket!leonard CIS: [70465,203] "I'm all in favor of keeping dangerous weapons out of the hands of fools.
