Robotics Monday: Self-Driving Cars and the Hall of Fame

I wasn't sure what to post today so I thought I'd try something a little different. To celebrate the admission of both the LEGO MINDSTORMS NXT and the self-parking car into the Robot Hall of Fame, here are two LEGO MINDSTORMS NXT versions of the self-parking car - both with video.

Here's the first one - it made the rounds on a few blogs, so you may have already seen it.

The second one (below) features a clever way of making a single ultrasonic distance sensor act like two to allow for more precise parking. This one appears to discover obstacles on the fly and decide how far to drive, while the earlier 'bot appears to use dead reckoning.
