Creating...tractor treads? Not sure what to call them.

Hey, I’m working on a robot, with caterpillar treads similar to those in the picture, but I’m not sure how to go about creating the treads for it…
Sure it’s a pretty typical question…sorry…
I used the search function.
Too many results of WIPs and FPs.

Sorry to bug you.
But, I’m lost…


This may or may not help:

Have a look in BlenderArt Magazine issue #19

Make a curve with the shape of the tread, then make one part of the tread and give it the array modifier, then the curve modifer so that it duplicates the tread and goes around the curve. (btw the curve and the tread must have the same location for their object centers, usually)
