Re: 4WD Turning Difficulties

yesterday we were driving our 2007 robot with the rover wheels on the regolith, the results were interesting, we found that the inline CoF is higher then .05 inline, more like .12. the robot wieghed 110lbs and had more then 50newtons of pull (it maxed out a force sensor we borrowed from a physics lab) also when we were driving at our max speed we could stop one of the drives so that we would be dragging the left or the right, and we would continue moving in a straight line with very little pull. (newtons first law)

once we got a second force sensor we were reading a pull of approx. 60 newtons.
