To me, the 2013 penny feels like it's made out of a different, lighter material. The first time I held one, I thought it was a fake. I couldn't find anything online, however, that indicates it's made of different material.
Deberah, I agree that mind-controlled robots is an interesting development in robotics. There are different research efforts underway; we covered one of them here: http://www.designnews.com/document.asp?doc_id=254726
mrdon, thank for the enthusiastic response. I think it's your second suggestion: those of us who've been reading science fiction for years while technology has been progressing to the point where we can actualize what we've been visualizing. I think this is true in robotics, in consumer electronics, and in film (Lord of the Rings, Avatar, e.g.).
Thanks for your feedback, bobjengr. It's comments like yours that inspire me to find even weirder, more talented robots :) No sarcasm implied, I really mean it. And yes, it's tough to keep up with all this: the pace of change is mind-boggling, and reminds me of several earlier, similar phases in Silicon Valley when enough brilliant minds and research dollars, plus the right levels of underlying enabling technologies converged to produce world-changing products. You know, like the iPhone and Web browsers.
Linear guides are one of the most important components required for the development of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides in machine design, can enable designed-in functional features.
