It seems about the right time to start a new thread as we have now turned East to Endeavour.
Hope no one minds... -------------------- -- Robin

As I recall the wheel current issues were somewhat alleviated by reversing driving direction now and then. I wonder if they have considered a pirouette kind of driving routine for long distances. The rover would drive 40 meters or so, stop and turn 180 degrees and resume driving in the other direction. While that might be hazardous around purgatoids, out on the flat plains it might make sense.
-------------------- If Occam had heard my theory, things would be very different now.

QUOTE (ElkGroveDan @ Apr 5 2010, 03:47 PM)  As I recall the wheel current issues were somewhat alleviated by reversing driving direction now and then. I think rest was found to be more important than reversing direction. Check out this post from Paolo.Paolo's posts are a goldmine of information. In this one he mentions that RF currents drop substantially on bedrock. Perhaps we can expect some drop in current on flat tarmac compared with the current ripples? I'm thinking along the lines of Spirit's wheel resistance in Troy that was reduced when they did the swimming stroke motions? Of course Spirit's case was much more severe. But perhaps a reason to hope for slightly longer drives on the tarmac. |
