I agree, Ann. It's more realitic than the Festo jellyfish, and a whole lot bigger. Watching the video, you'd think this giant jellyfish was real if you couldn't see the control mechanisms on the bottom side.
This again is another example of a more "beautiful" robot...though a bit scary, too! Not sure I'd want to encounter a human-sized mechanical jellyfish in the sea (where I spend a lot of my time). But in all seriousness, this is really cool...and its aim is a good one as well.
Hi Ann - another inspired project and another inspiring article.
Biomimicry really has taken amazing strides recently. At some point, the developers will have to remember that almost all creatures have natural nemeses. So making a really large natural looking jellyfish robot may shorten its useful life because it may look a like a nice meal to a passing sea turtle.
Or in the case of the dragonfly robot, a passing bird.
Clinton, thanks for your comments (and for using the correct plural of a Greek word: nemesis, pl. nemeses). You bring up an interesting point that some other commenters have mentioned: what about predators thinking that a realistic robot is potential food? This jellyfish is bigger than most, if not all, sea turtles, but a killer shark could be a problem.
Cabe, "most efficient" defined how? I've written about several different swimming robots, modeled after tuna, sea turtles and jellyfish. Each of these was described as highly efficient and/or with an optimum size or function(s) for the tasks it was designed for--and they weren't all the same set of tasks. Most robotics R&D is past the stage of fundamental research and is now applied to a specific end-use. OTOH, there are also some competing designs for similar uses.
Cabe, so you mean the basic physics definition. I still think that the usefulness of the robot's motion in the particular application is just as important as the physics in the abstract. This has become especially clear as I've been working on a nautical robots slideshow, where designs can be wildly different depending on end-usage--or wildly different to achieve the same basic purposes.
CLMcDade, I agree about the project being inspiring as well as the article. The field of Biomimicry has no boundaries and limits to creating magnificent machines. I'm really impressed with the waterproof material protecting the electronics and the graceful movement of Cyro's legs. Nice work as usual Ann!
What a great piece of engineering, it certainly mimicks a real jellyfish in motion. My question is about directional control and how does it steer, which are not so very obvious. But I can see that it could run for quite a while, since it does not need to run to stay afloat.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
