Thanks Chris!

Great Paper! Something more for our students to nibble on. And they say I make them think too much already!

(I downloaded the ā€˜Wordā€™ version earlier, it is my prefered format)

I hope that the paper is useful for some teams. Iā€™ve read countless posts on these forums that say, ā€œHELP! Our robot wonā€™t turn!ā€ Iā€™ve responded to most of these posts with some rules-of-thumb, but posting the math is usually too difficult.

Iā€™ve had these equations scribbled down in various notebooks and loose pieces of paper for quite a while now. Iā€™ve been wanting to formalize them into a paper, but I guess Iā€™ve always been too busy to finish it. Iā€™m glad itā€™s finally done.

Good luck to all.

Chris,

Great paper. Very detailed. I have one comment, though. The one thing I thought was missing was the use of different materials on the front wheels and back wheels of the robot. If a rookie were to look at your paper, they would get the impression that there would only be two ways to help turning: (1) width must be larger than wheelbase or (2) Wheels with different friction characteristics in the different directions. There is, in fact, a third (and I know you already know this) and that is to have the front wheels and back wheels have materials with different coefficients of friction. I know the equations get a bit longer, but it may be worth it to point it out.

Great job on the paper!

Paul
