That's pretty neat, thanks for posting the link Bart! What I find interesting is that it doesn't appear to "see" where it's placing it's feet so much as react to the effects after they're down on whatever surface it's traversing. Then again, in the later section of the video where it appears to be "bounding" it seems to jump over a section of the track.

There was a Finnish subsidiary of John Deere that specialized in forestry equipment and they developed a hexapedal tractor for getting through protected areas of forest to perform selective logging operations. Here's a couple clips as found on YouTube: http://www.youtube.com/watch?v=b1h3vcLybfA and: http://www.youtube.com/watch?v=0gk-yQ1H3M8&NR=1
Pretty wild, especially with all the articulation, and I've seen a couple clips on the original manufacturers site (apparently they're now defunct) showing it moving at faster speeds.

RFDTV had a recent "Classic Machinery" that featured another walking tractor from the 40's or 50's that was designed to work boggy areas in Canada, but I couldn't find any online clips to post. Neat stuff!

Speaking of the MadCat with PPC's... Not quite that, more like the "Flea", there's this classic clip: http://www.youtube.com/watch?v=FtovadY4lYk
