Small Halftrack 2

One day, young humanoid was looking at a picture of his project "Small Halftrack" and thought "I can do better!" So he made this. I have to agree with him, this one is better. Young humanoid implimented two light sensors to use as lights, an ultrasonic sensor and a tilt sensor to detect if the halftrack was being tilted. He also made the front of the robot look better and added a flip-up cover over the NXT.

Mini Bulldozer/Loader

Let's move on.
Young humanoid made this machine to have the ability to tilt and raise its scoop using one motor, leaving two open for driving. The mechanism worked pretty well, and also came with another advantage: The scoop could act like a bulldozer blade when it was in its downward position.

The Horseshoe Crab

NXT+NXT+RIS 2.0+Power Functions+PS2 Controller=26 AA batteries.

Once again, both. I thought that young humanoid would stop at The White Tortoise, but I should have known better. He bought an interface that allowed NXT to be controlled by a PS2 remote control, and he connected a few beams, put in a couple of pegs, attached a lot of motors and lot of batteries. This one had a lot of the same things that its predecessor had: Two rubber band guns, a mini bot, lights, ect. But it was missing the missile launcher and picked up a rubber band turret that could rotate and fire. This machine also included a automatic tailgate. But the main advantages this thing had over The White Tortoise was its much-enlarged remote-control range, and it could turn. Its main disadvantage is that it looked bad. And what do I think? A HUGE waste of batteries!

Thanks to LEGO's discontinued theme Exo-Force and rammjet's project Armadillo for the inspiration.

NXT Power Functions Truck

Young humanoid combined his NXT with Power Function elements again, and got this load-pulling truck (and trailer!) . Unfortunately the design of the truck was really bad, but other than that it was okay!

Copier V2

Young humanoid wanted to make a more compact version of his old copier, so he built this. This one worked pretty well. A 3x5 card with the image to be copied was inserted into the rear of the machine, and the robot put out its copy of it on adding machine paper.




Here are its best copies:

Tank V3

Young humanoid was not satisfied of how his earlier project Tank V2 looked, so he moved on: Tank v3. This one was better, but it said some drawbacks, the turret could not rotate unlimited, the base was too small and the NXT was upside-down.

Dune Buggy

This was supposed to be some kind of dune buggy. Young humanoid geared up the rear wheels to make it faster, but it had massive trouble turning at top speed. Also its NXT brick was not connected well. Not the greatest project, but who would expect greatness from anything other than the X series?

Platform

Young humanoid really doesn't know what to call this one's drive system. It worked pretty well, and to make it more interesting young humanoid added a turret to the top of it that could rotate unlimited times around and fire a missile! Of course, he would not think of making it autonomous...
