Robot amputee waving hello icon
Researchers are building a prototype design that would enable a two-legged robot modeled on an ostrich to run at around 50mph. In simulations, it can already outpace human sprinters. I don't see any evidence that this this is anywhere close to existing, or in fact that they have anything "done" besides a computer model and animation of two funny looking legs "running" while suspended in mid air.
Other than perhaps a robotic supersized drumstick for Chrimbo? Exactly the point in fact. With cameras multiple wave lengthsand ultra sonic scanning, it would probably notice a trip wire a lot easier that a human would. Hmm, nah, it would be doomed to failure from the start, especially if it was built by Acme Corporation!
Fine robot amputee waving hello icon you're a student; worst case scenario your end-of-term paper is late and poorly researched. It won't be the only one. But if you're in charge of military research somewhere I'm just trying to work out who I could have offended with that one. I'm guessing either a student with an overdue paper, an arms merchant who's worried his dirty little secret is out or a pixie who wants to discourage the wholesale consumption of his housing stock.
Otherwise they wouldn't be building robotic velociraptors programmed to stalk puny humans!! Evolution has had quite a few goes at getting ostrich legs just right. Less efficient designs get eaten. I'm surprised these peeps think they can just study some video and "devise a more efficient mechanical system". Ostriches will have muscles in their lower leg for a very good reason, which so far seems to have eluded this crowd. And as for "In simulations, it can already outpace human sprinters", well, in simulations I can land a robot amputee waving hello icon an aircraft robot amputee waving hello icon.
Come back when you've actually got something to tell us I get the point you were trying to make in that simulations cannot accurately model the real world perfectly but you do your argument harm by using a bloody silly 'I can land a on a carrier in a simulation' analogy. Everyone with half a working brain knows that that would be impossible in any reasonably realistic simulation and we are giving the benefit of the doubt to the scientists that they are using a relatively accurate simulation software rather than 'Looney Toons Physics simulator V1.
That would be awesome! A US fleet carrier can steam into the wind at about 30 knots. Now, the stalling speed of an unladen with full flaps and pretty much bingo fuel is knots. That's a net approach speed of 85 knots. Now, if we assume a good, solid 70mph gale over robot amputee waving hello icon deck, that's 60 of those knots dealt with, leaving a mere 25 to be dealt with by reverse thrust and braking in the length of the deck.
Of course the wing would probably hit the island and there's absolutely bugger all margin for error, so you wouldn't want to do it, but it's quite possible. It took hundreds of millions of years for evolution robot amputee waving hello icon natural selection to come up with the ostrich leg but it's not that difficult to come up with a more efficient mechanical system.
Evolution produced an ostrich that has to be able to grow from a tiny fertilised ovum into an adult bird. It also has to be able to repair itself for damage and wear.
The power source has to come from digested food. The mechanical leg is free of those requirements. Gentlemen, we have the technology. We have the capability to build the world's first robot ostrich. Better than it was before. As you point out in your own post its only 'quite possible' if the simulator ignores the fact that the plane has wings. You can see videos and pictures after a quick google. The C has a wingspan of about ft and JUST managed to fit without decapitating the carrier and suddenly leaving a lot of promotion prospects for the lower ranks.
I also doubt, but cannot prove, that the wing height off the ground is not enough to go over the tower. Human amputees can run pretty well on replacement legs that are essentially a single piece of spring-steel. A real bird has to be long-lasting. A robot doesn't need to run for 10 years without wearing out. Also, some systems that are efficient, can be ill-suited to evolutional processes if there isn't a way to get there through many gradual iterations.
So planning the final result, it's possible to create something evolution would never have got to. Regrettably, they cannot expect it to exceed expectations at the moment, they can only expect it to meet expectations. That's what expectations are. Later, of robot amputee waving hello icon, when it is all over, they may look robot amputee waving hello icon and realise that it did indeed exceed expectations. That'll be nice for them then.
It's just too soon for that now. Here's some more details on how it moves. Its a very interesting design but I think the 50MPH is more than a bit speculative at this stage. At this stage of design in the following video, it reminds me very much of a Theo Jansen style of leg design If you've never heard of Theo Jansen, look for his amazing work on Youtube.
If you search for "Theo Jansen mechanism", you will find animated diagrams of how it works. Simulations are used to do the normal engineering math that is impossible to do by empirical trial and error. Complaining simulation has been used to design the parts is like saying we shouldn't use equations to build bridges. Look at some state of the art style passive walkers http: Computers are used to make sure the legs are balanced and will operate passively or in this case use one motor to drive many jointswhich was highlighted as an innovation in this work.
If it does, it's probably something like "Based on the computer simulation, we expect robot amputee waving hello icon should do X well, but we don't trust the simulation, so it might be better, or indeed worse".
I wondered why no-one had pointed this robot amputee waving hello icon. How difficult would it be to trip or topple a two legged device, robot amputee waving hello icon much engineering would have to go into making it self-righting?

James 63 - Devising a more efficient mechanical system It took hundreds of millions of years for evolution and natural selection to come up with the ostrich leg but it's not that difficult to come up with a more efficient mechanical system. The mechanical leg is free of those requirements, Gentlemen, we have the technology. Idiot As you point out in your own post its only 'quite possible' if the simulator ignores the fact that the plane has wings. To re-assert the previous poster, in any reasonable simulator it is just not possible.

The past 12 months have provided many eye-grabbing headlines from the Imperial community from world-leading research to incredible inventions. Before is upon us robot amputee waving hello icon its own wave of news, we take a quick look back at the most popular articles on our award-winning news site ranked by the number of page views.
The team explained that detecting signals from spinal motor neurons in parts of the body undamaged by amputation, instead of remnant muscle fibre, means that more signals can be detected by the robot amputee waving hello icon connected to the prosthetic.
This means that ultimately more commands could be programmed into the robotic prosthetic, making it more functional. Read what the New Scientist had to say about the study. This new five-minute test, developed by Imperial researchers in robot amputee waving hello icon with Newscastle and Aberystwyth universities, can detect markers of such foods as red meat, chicken, fruit and vegetables, as well as how much fat, sugar, fibre and protein a person has eaten.
Read what the BBC had to say about the test. In his individual final year project he developed an AI software program that could automatically understand a video game and learn how to play it from only seeing pixels on the screen. He was always remarkably self-driven and I am not surprised to see him go on to such great success. The study, published in the Infant Mental Health Journalrevealed that fathers who interact more with their children in their first few months of life could have a positive impact on their baby's cognitive development.
The effects of psychedelic drugs on the human brain always captures the eye of Imperial news readers, and this story was no different. Robot amputee waving hello icon present findings may help us understand how this can happen. Coffee drinkers around the world rejoiced when this research landed in July. The landmark study, carried out by Imperial and the International Agency for Research on Cancer IARC found that people who drink around three cups of coffee a day may live longer than non-coffee drinkers.
In short, it was found that higher levels of coffee consumption were associated with a reduced risk of death from all causes, particularly from circulatory diseases and diseases related to the digestive tract. Understandably, the story was picked up widely in the press. Carrying extra weight could raise your risk of heart attack by more than a quarter, even if you are otherwise healthy.
This was the main finding of the fourth most read story on the Imperial news site of the year. Also on a healthy living theme, this study announced in February revealed that a fruit and vegetable intake above five-a-day shows major benefit in reducing the chance of heart attack, stroke, cancer and early death. Where five fruit and veg a day is good, 10 is better — this is the general line which the press ran with, as these articles from the GuardianBBC and Daily Telegraph demonstrate.
The study made the Altmetric top list of the most discussed journal articles of They were able to do this via spectroscopic ellipsometry, a method normally used by the researchers to study the effect of different films applied to the surface of solar panels.
The story really found its audience on the social news platform, Reddit, where members of the History subreddit community shared their fascination in the time traversing applications of science. Researchers from the Faculty of Medicine used psilocybin — the psychoactive compound that occurs naturally in magic mushrooms — to treat a small number of patients with depression in whom conventional treatment had failed.
The researchers described patient-reported benefits lasting up to five weeks after robot amputee waving hello icon, and believe the psychedelic compound may effectively reset the activity of robot amputee waving hello icon brain circuits known to play a role in depression.
When the study was published in October, it gained a lot of interest in the media, including NewsweekNew Scientist and the Guardian. Sign up to Imperial Today.
