When Is a Robot Not Mechanical? When It's an Android

Seems like there is some great research potential at the heart of this project. Rat heart muscle cells--curious about that one. Anything about the rat heart muscle that lends itself to this or is it more that rats are the go-to source for research?
Beth, rats are definitely one of, if not the, most common animals used in lab experiments. They are bred specifically for this purpose. And incorporating living bioengineered tissue into robots appears to be a trend. I'll be posting on this subject again soon.
Lou, I think it's unfortunate that the term "android" has been co-opted by a commercial enterprise, and not very accurately, either. Regarding the Medusoid, I agree about the control system--I'm really curious to know what they have in mind. This isn't quite a robot yet, or an android, but with the correct control system, it could be.
Although they are bred for lab experiments, I never really thought of it going much further than rats more than getting injected with drugs that are undergoing testing, or having makeup put on them (wink).
Seriously, though, putting living tissue into robots is a tad bit creepy. More and more, after reading your posts, Ann, am I beginning to understand the term uncanny valley and why it's real.
Lipstick on a rat?? Hadn't heard of that one. I agree, Jenn, it's getting creepy when we start combining engineered living tissue with machines. But also fascinating. I think that uncanny valley may be expanding into more of a continent at this point.
I agree about being creepy and fascinating at the same time. It seem's like a mad scientist movie where life is being created in a lab. I like robots with a mechanized appeal but when they start looking and acting like humans that's where I draw the line. Fascinating article.
Great coverage, and I hate to be the robot dork raining semantics down on the parade, but... This naming of robots/drones/cyborgs/androids issue is really starting to spiral into unmitigated ambiguity, so with all due respect, mitigation: this is certainly a novel robot, but I'm afraid it's not an android - the greek preference "andro," from which the word is derived, distinctly implies "man," and "oid" is of course... well, "of." Sure, meanings of specific words change over time, but this isn't one of them.
As examples, the terminator is an android. It's also a cyborg. ASIMO is an android, but not a cyborg. Both are robots. Predator and Reaper drones aren't robots, they're supertech R/C planes. So what do we call the starfish and things like it? I suppose we might just need a new standardized word for these non-mechanical artifcial moving things!
It's a complicated issue that a dictionary alone won't solve. I've addressed it a bit here: "WarBot Update: What to Call the Drones Now that They're here at Home – Suggestions?" http://goo.gl/Dxhh3
The biggest use for this that comes to mind for me is moving facial features on an android. The "muscles" used would have discrete electrical signals going to them controlled by a cpu or fpga of some sort. When you want the android to smile, particular signals are excited. When you want the android to smile really big, then those signals are excited with a greater amplitude. A frown is just different signals. This is not too far from how our faces actually work.
Obviously there are some hurdles to overcome and refinements to make to get to that point, but the basics of it can be seen in the video.
It wouldn't take much time to create a look-up table for appropriate facial actions (and store that in memory) to make an android have at least basic "emotions".
How many years before your household helping android is able to wink at you when he it cracks a joke?
Glad you liked the post, mrdon. A lot of robot R&D is starting to remind me of science fiction movies. The ones that look like people are really big in Japan, but I agree, they're too weird for my taste. DN did a survey on that subject, asking our Systems & Product Design Engineering and Automation & Control Engineering groups on LinkedIn "Should Robots Look Like People or Machines?" Here are the results: http://www.designnews.com/author.asp?section_id=1381&doc_id=237885
