We went with AM HD (am-3067) mecanums because they have aluminum plates instead of plastic bodies. Their 100 lb. per wheel rating is about double that of the 217-3644/45, which are listed as "conservatively rated for a 200 lb. robot."

I believe VexPro's ratings are conservative, because I know several of the engineers there and trust their design skills. However, based on their construction, the AM HD wheels seemed like a safer choice. We did not know in advance how hard we would be working that chassis.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
