The presentation gives very helpful insight into how StangPS works. There are some small math errors which may confuse some students viewing it. Worth discussing?

Perhaps. (I'm surprised it's not been brought up before; that video's been around for a while.) Is there one of your follower-wheel odometry posts that would be applicable?

If you are just interested in learning more about how to use LabVIEW to program your robot, including image processing, you could try this thread:

:-) ... OK. Lets' do it that way.

Question1: In the video, is the positive X axis pointing to the left or to the right?

Judging by the coordinate values given in the second half of the video, I would say the positive X axis is to the right, positive Y axis is up.

I think I see where you're going with this though... in that the diagram showing angle theta as an acute angle doesn't match the angle that would be calculated from delta-x and delta-y in the world coordinate system.

So to answer your original question, I think at this point it's probably just worth noting that the video is meant to give an intuitive sense of how things work and the general types of formulae that will be needed instead of being mathematically rigorous.

My request for one of your odometry posts was meant to ask whether you already had a post somewhere that gave the correct mathematics, as it seems like something you might have covered before.

Yes. As I said in post 5, the presentation gives very helpful insight into how StangPS works.

Aaron.Graeve did an admirable job of explaining the math in this thread. If anyone wants to explore this further, that would be a better thread to discuss it, so as not to hijack this thread.
