Artemis Rover Simulation in Action (VIDEO)
Caption
Artemis is now being used to chart the best path for the Opportunity rover to take on and around the rim of the crater Endeavour. Over the weekend of Dec. 17-18, Opportunity automatically stopped a commanded drive on a rock outcrop because the right front wheel motor current (dashed blue trace in movie, above) exceeded a preset limit. The Artemis simulation showed that the right wheel current was high because that wheel was trying to do all the work of moving the vehicle, and that the rover could be extricated from its situation simply by backing it up.
