I hate to be the bearer of bad news, but I just heard that there is a serious problem with Spirit's right front drive actuator after yestersol's drive. (This is the actuator that had high currents in the past and led to the backward-driving strategy.) It will take awhile to evaluate the situation, but early speculation is grim.
In a worst-case scenario, they can still drag the bum wheel along, but don't expect another summit view. Best-case scenario would be a rock or debris jammed in the wheel. This is a heads-up, sorry I can't really give more info at this time. I still thought you all would like to know. |

On the weakly positive side, I hope that the wheel motor circuit is dead open (if it has to be open at all, I mean...rats! ) This will at least remove a little bit of load from Spirit's energy budget, though I know that the other wheels will more than overwhelm this due to extra torque requirements. A short to any part of the vehicle chassis from a hanging wire or a blown winding could prove fatal at this point...
