This is just a strange thing that crawls around using its "arm". My ultimate goal is to add CMUCam3 and get the thing to follow some objects by crawling towards them. Locomotion is veeeery slow and suffers from bad traction of the arm. Initially I did use the claws that come with NXT kit as the end of the arm but they had zero traction so I decided to use the rubber wheel instead.
And yes, I do realize that in the title picture it looks like the robot has a serious hard-on :-D
