- I wonder how they define "live robotic control"? What are they actually
- controlling from Goddard?
-
- Robotic spacecraft (ie. Voyager) have been
- controlled/reprogrammed from earth. I think this would win the prize
- for the greatest distance for remote control of any kind.
-
- The Soviets had an lunar vehicle called "Lunikod" ( or something
- like that) which was controlled remotely from earth.
-
- In the Robotic Systems Evaluation Lab at NASA-JSC, a robotic manipulator
- was controlled through a TDRS satellite link from Houston to
- White Sands and back. This commands traveled from an operator in Houston,
- up to a satellite, down to White Sands, back up to a satellite, and then
- down to the robot in Houston. Feedback from the manipulator took the same
- route. This was an experiment to evaluate the time delay that would be
- involved in the ground control of robotic maintanence tasks for Space Station
- Freedom.
-
- But enough of that ...
-
- I am sure that we will learn alot from the Erebus expedition, and look
- forward to more news to come. Good luck to those on the ice!
