Obewan,
I wrote a little email to JPL this afternoon regarding their "..slightly ill.." robot on Mars.
Thought you might get a chuckle out of it.
"...Hello,
Sorry to bother y'all at this juncture, but has anyone at JPL asked the question "..can one rover help fix the other one.."...???
The news article I read said you folks think it's a "..piece-part or cable connection.." problem.
What came to mind was that perhaps your "R2D2" could motor over to "R2D1" and give it a swift kick in the fuel cell, etc - so to speak. ( i.e.: bump a cable connector back into its socket, etc...).
Hopefully the design team attached a "Leatherman" multi-tool (or McGyver's Swiss Army Knife ) to each rover, so they can do a little tinkering if need be.
Best of luck.
John ..."
Tee hee hee.........
