It is a tough call but I think you could check this out and maybe blog about it. It is called "Big Dog". Watch the entire video because it is amazing to see the robot counter ballance itself. It actualy reacts to unforseen stimuli.
For example, the robot is kicked from the side and does not fall over, it steadies itself. It is kind of creepy. It also walks over strange terrain and compensates for the unevenness.
The reason I say you should look into it is because it must have some form of very advanced A.I. going on. Plus, it can carry like 300 pounds of load and still function. That is just NUTS!!!
I thought it was cool, surreal, and scary all at the same time.
