Remember Tank? Well, after young humanoid got some new Power Function elements and the like, he make the second version of Tank. This one had some new features, it used tracks instead of wheels, it could raise and lower its gun as well as fire it and it could rotate its turret unlimited times around. But some bad points arose. It didn't really look like a tank, and its turret could not operate its driving base when it was rotate away from facing forward. Like the first version, it was remotely controlled via a second NXT.
