DARPA Crusher Robot
 

Here is a link to a robot vehicle developed by Carnegie Mellon for DARPA. It either goes around or runs over obstacles in its path. Wait until near the end when it crashes through and then runs over a couple of cars.

This vehicle is quite amazing, most people don't realize that Crusher has been around in some form or fashion before the Darpa Grand Challenge took off in popularity. Since Crusher is partly government funded it did not compete.
