spider robot aniamtion

I found this animation of a spider robot with 6 legs. I love the quality of this work, the motions are very smooth and there is no unintended, sliding as it moves. The robot was made a rigged up using 3Ds max and was rendered with an external renderer called brazil, which seems to have added the ambient occlusion effects. I think the ant-aliasing settings in the renderer must be quite high as it looks nicely defined and has a high resolution even on youtube.
