USING IT TO MOVE ROCKS UNDER THE WHEELS TO GAIN TRACTION?
Not impossible, but again the IDD isn’t that strong. Lots of little rocks maybe, that unfortunately are not readily stacked about anywhere. USING THE IDD FOR TRACTION – The rover cannot drive while the IDD is in motion at the same time. Consider this also, if the IDD was lodged against the ground, driving over it, the wheels could get a good grip – BUT, then the IDD (the main science instrument) would be useless.
