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.
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.
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
Yes, there does seem to be an explosion of robotics going in a surprising variety if directions, Ann. I get the impression that developments in robotics has accelerated tremendously in just the last five or six years. Maybe it just that I'm aware of it lately.
Rob, I think it's not just your awareness, but a definite explosion, with several trends coming together and interacting, including open source software, cheaper and better electronics (such as cameras and MEMS gyros and other sensors), and the biology angle we're starting to see more of.
Hmm. I didn't realize open source software was part of the development process of these robots, Ann. I'm sure that's hugely helpful. At any rate, we seem to be in some golden age for developments in robots.
Ann, what are some of the other trends driving developments in robotics? I would imagine advances in motion control is a factor. From you articles, it also sounds like funding at universities is helping. Military funding also seems to be a factor. The filling of specific needs seems to be less of a factor. But I may be wrong about that.
Rob, as I mentioned, several trends are coming together and interacting to boost robotics development, including open source software and cheaper and better electronics (such as cameras and MEMS gyros and other sensors). No doubt motion control advances figure in there, too. Did you have some specific one sin mind? In addition, the Medusoid is an example of the emergence of biorobotics we're starting to see more of.
What made me curious, Ann, was the growing number of robotic developments that don't seem to be specifically tied to solving problems. Seems like a lot of the developments are raw research -- which I think if great. I would guess that part of it is that working on robots is fun.
Thanks for explaining, Rob. From what I've seen, most of the new, exploding research is aimed at solving very specific problems, and much of it is being funded by the military. A considerably smaller amount, such as Medusoid, is aimed at fundamental, or "raw", research, but a lot of that looks applicable to some the purpose-driven work.
Interesting that the military has such a large role in robotics developments, Ann. I would imagine it's like an iceberg -- what the militrary reveals is probably a small portion of the overall work in this area. A good portion of it is probably secret.
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.
About misnomers, I agree; my pet-peeve is the marketing ploy that misguides public thinking down their agenda's pathway: (Android; Hybrid; i-anything); --- to the point where an entire generation doesn't understand the meaning, yet they all think You're the idiot who doesn't understand.
But I digress ,,, Reno at Anthrobotic has addressed the Name-Game issue quite well, so I give that topic over to Reno, and read intently the subject-matter jungle of uncharted territory he's entering.
Meanwhile, back to the point. Combining engineering materials with once-living tissue and literally bringing them to life ,,, well, its literally Dr. Frankenstein, and its happening in real life nearly 2 centuries after Mary Shelley penned the original story in 1817. Remember it was electricity that brought the being to life. Science mimicking Science Fiction, yet again. Fascinating, Ann. Looking forward to additional posts on this topic.
Ann, great article and I loved the video. Though crude, the movement was much more lifelike than I anticipated. My mind reels at the possible applications to real-life biological systems. I expect the field of bio-ethics to explode in the next 10 years as we humans grappled with these developments. As you say, this is the stuff of Science Fiction staring us right in the face. Exciting to say the least.
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?
Regarding definitions, I agree it's complicated. Since the technology is changing, so are the terms and their use and meaning. We've read about androids, implied to be human by their name, for decades in science fiction. But until very recently, the technology wasn't available to combine mechanics, electronics and living tissue. Now it is, and so far it doesn't look human at all: it looks like a jellyfish and some other things we'll be reporting on soon. But the only term we've got is android, so that may have to do for awhile until we come up with a better one that doesn't imply human form. As I commented in another thread, general dictionaries are good for defining broad, commonly used vocabulary terms, but not at all useful for fast-moving, highly specialized fields like science and technology. Wikipedia is usually a lot more reliable. Here's what it says: http://en.wikipedia.org/wiki/Robot
Since the article mentioned that that the device (maybe not the right word there) using living tissue, I was wondering what they are doing to keep it alive? Is it simply extracting the nutrients it needs out of the solution it is operating in? Taking that thought one step further, what is the life-span of something like this and how are the non-living parts recycled with new heart muscle?
By the way, I was thinking the same thing that naperlou said. From the title, I was wondering about a robotic cell phone.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
