One Giant Step for Humanoids
An anonymous reader writes "There are a few robots that do amazing things. Honda's Asimo can walk backward and climb stairs. Sega's idog can dance to music. A tougher nut to crack has been making robots walk like humans. Today, scientists introduce three humanoid striders at the annual AAAS meeting. Unlike other robots that have to power every move, these three save energy by letting gravity do a lot of the work. Like humans, they pick up their feet and just let 'em drop. Engineers say they'll inform the next generations of humanoids and also improve design of robotic prostheses for people. And hey, why not send them to Mars to look for those microbes?"

Robotic or semi-robotic prosthesis are going to be more and more in demand because ironically of advances in battlefield armor. Current flak jackets (body armor) and helmets are protecting the vital bits of our soldiers, but often limbs (and necks) are sites of damage from explosions and firearms. Many of these soldiers are undergoing amputations either in Iraq or more commonly in Landstuhl, Germany and coming home with prosthetics of varying sophistication.
There are a couple of interesting recent additions to the Internet that cover these issues. One is an article by Steve Silberman in Wired and the other very interesting site is Stuart Hughes blog. Stuart is a world news producer with the BBC who unfortunately stepped on a landmine covering the Iraq war and now writes fairly frequently about "stumpy" and his prosthetic leg.

Maybe there are more efficient methods of locomotion.

"...save energy by letting gravity do a lot of the work. Like humans, they pick up their feet and just let 'em drop."
That makes sense, but humans don't really just let their feet "drop." Our steps are actually quite controlled...if we just let gravity pull them down, we'd have pretty heavy footfalls, not to mention an awful lot of shuffling...
I saw the MIT robot this past summer stumbling around outside Fenway park after a Red Sox game! He walks like a drunk...

Oh sure, they can walk like me. But what's their record on Dance Dance Revolution?
Paul Grosfield - the quicker picker upper.
there are probably better forms to send there. The rovers are interesting, but they can not cover a large amount of terrain at a time. It would probably be better to have some sort of a flyer, so that it can move quickly for long distances.
I prefer the "u" in honour as it seems to be missing these days.
im happy. The asimo ran like an old lady.
and some of them are programmed to think they ARE human..
With the current drive to put robots into the front lines of the battlefield, and perhaps build combat robots, this application would fit right into the scheme of building a fighting robot.
I'm up for anything to give our boys a leg in this fight. This is it. I hope the Pentagon can find a way to apply this technology.
Darn, I was hoping for one step for Giant Humanoids!
I wish Honda would do something with ASIMO that is actually useful. Send him to work at McDonalds (yes, I recognise the irony of spending millions of dollars to replace someone who gets paid minimum wage) or at an old folks home or something. Instead of focusing on the intricate details of "standing up" and "walking forward" why not choose something for him to do, and solve all the problems needed for him to do it. But don't invent Yet Another Bi-pedal Locomotion Technique, that problem is solved more than enough to move on to the next problem.
How we know is more important than what we know.
Humanoid! Fetch me a beer! Nice humanoid.

Probably because there are much more efficient ways to locomote. Bipedalism is risky, especially if you want to bend over a lot to pick things up.
I'm in favor of a radially symmetrical spider-like walker that can turn in any direction, or even invert it legs and continue walking if it gets turned upside down. This would make it much more flexible in navigating the Martian environment.
You could have a central ring with legs attatched all around it, and then a rotating body that includes sensors, power supply, and a grappling hand. The single grappling hand descends from the center and pulls samples up into the body for storage/analysis.
Computers are useless. They can only give you answers.

Cred to Neil and the Bonzo Dog Band.
Hats off to the folks who are working on these robots. They truly are amazing bits of engineering. But are we really so narcissistic that we think something that looks and acts human is a good design? After all, the robots that really are useful to us (mostly in manufacturing) don't look human.
What does this button do...
Look out! Striders! Somebody get the rocket launcher!
It still takes a long way to have those robots learn running, crawling, dodging, rolling like Indiana Jones (or Lora Croft, if you prefer your robots feminine). Until then, I won't recommend them for a mission on another planet.
Seriously, insectoid robots are obviously much more suitable for terrain expedition.
Humanoid had to be the worse design as far as robots go. For animals it works because it would be hard for there to be an organic life form with wheels. Maybe something like a self driving segway would work well. They have that other segway wheelchair that climbs stairs and everything. If they spent more time designing the robots to do actual task like identifying objects, picking them up, and operating them, instead of spending the time trying to make them walk, we'd be a lot further along.
Anthropic principle: We see the universe the way it is because if it were different we would not be here to see it.
I can't help it, but alongside the pride and excitement I feel whenever I see technological progress like this I have this tinge of frustration.
How much money is spent every year on perfume? how many great mechanical engineers are working for sea-doo?
I mean, we could have so much more! Not just in robotics but chemisty, physics, space exploration...
But, alas, I know that all work and no play makes humans a dull animal and that that perfume makes ladies smell very nice. Nevertheless, I cannot help this tinge of disapointment which inevitably follows my rush of happiness.
Please continue the research... I am still waiting for my fembot to get laid!
PhysOrg.com has an article on the same subject, in which it describes how these 3 robots walk, for instance: "The Cornell robot supplies power to the ankles to push off. When the forward foot hits the ground, a simple microchip controller tells the rear foot to push off. During the forward swing of each leg, a small motor stretches a spring, which is finally released to provide the push." Fascinating stuff. I have the link to the article on my blog: http://sundroid.blogspot.com/, if anyone's interested.

I just got my wife a Roomba robot vacum cleaner, and I have to say its one of the coolest things I've seen in a long time. It makes us feel like we're finally in the 2000's to have this little robot rolling around picking up cat hair while you are free to do other things.
I get really excited about the prospects of putting robotics to use in the home. Sure their use in science is great, but its pretty cool to have "Rosie" cleaning up!
Sound waves should be free!
To do any of the things you just mentioned would require strong AI, and nobody has made any significant progress on that front since ... well, ever.

The MIT robot normally walks properly like a human. For the "after the game" demo they wanted to make it look like an "after the game" human. Took a lot of effort to get that right!

I work at Honda, and let me tell you, Asimo exists for a reason:
So they have an excuse to give out tiny Asimo action figures whenever the president sneezes!!!
This website has a neat video of dancing robots on it. It obviously doesn't carry the same implications
that a low-energy walking robot does, but the motor control and balance gyros and the what-have-you
needed for this act are still pretty impressive.

I'm still a little skeptical about this whole humans creating robots thing. I mean, I saw Terminator 2 and the outcome was not pretty.
These 'bots are great but they're still kids toys compared to advanced Westinghouse designs from the 1930's. When this robot finishes a task he even takes a smoke break !!
I don't understand why they try to make human robots. If you think about it humans are not very specialized creatures, we can do a little bit of everything. run, swim, jumb, crawl, etc. They should make robots specific that way they can do a few tasks great as opposed to all tasks decently. For instance, if you want a robot that will take beer from your fridge, why would you make a humanoid robot that walks perfectly?? Just make two wheels and an arm that can open the fridge and pick up beer (or other items from your kitchen). Specialized robots would be cheaper, smaller, and more efficient. You could afford more of them and more people could afford them.
One king doesn't like the other king so he goes beats him up. Unfortunately he also gets hurt in the process.
Hey instead of **me** being hurt I'll send some blokes (==soldiers) over to beat up the other king.
The other king doesn't like to be beaten up, so he puts his soldiers in the way. We now have two armies beating eachother up.
Hey let's not send our soldiers into the battlefield to get hurt, let's send robots. Nobody gets hurt. Soldiers can sit at home and eat pizza.
The enemy then gets pissed that these robots beat up their people and build their own. Now we have robots beating up on robots.
Next, the one army gets pissed that their robots are getting beaten up and start hacking the enemy comms to stop the other robots. The enemy responds by hacking the hackers...
So what's the logical conclusion? Is war going to just end up being a big computer simulation with nobody getting hurt? Perhaps the kings should just go decide over a nice game of chess!

Efficient Bipedal Robots Based on Passive-Dynamic Walkers
Steve Collins, Andy Ruina, Russ Tedrake, Martijn Wisse
Passive-dynamic walkers are simple mechanical devices, composed of solid parts connected by joints, that walk stably down a slope. They have no motors or controllers, yet can have remarkably humanlike motions. This suggests that these machines are useful models of human locomotion; however, they cannot walk on level ground. Here we present three robots based on passive-dynamics, with small active power sources substituted for gravity, which can walk on level ground. These robots use less control and less energy than other powered robots, yet walk more naturally, further suggesting the importance of passive-dynamics in human locomotion.
Wow, the one from Delft is so minimalist it doesn't even look like a real robot, more like a movie prop of a science project. Considering the bulk of some others like Asimo, and that true bipedal walking was big news only a couple years ago, reducing it to such a simple package is pretty amazing!
In my day humanoid robots had to lift their legs uphill in the now both ways. That is if you had legs. My best friend got along fine with a set of wheels.
These modern robots and their "gravity assisted walking". How Dreadful.

I have been thinking about the recently anounced cell processor and robots, I think it will be excellent to use it in them. Remember that 2 of the companies involved in the development of the cell are toshiba and sony , and those two companies are developing/sell robots. The parallelism that that the cell will provide will be excellent. Imagine an APU dealing with some pattern recognition algorithms while other deals with voice recognition and so on .... I start to see a future with home robots made by sony, industrial robots by toshiba and business equipment by IBM ....

One of those robots looks like those drones from Star Wars, and another like that robot from Futurama!
Obviously, these top scientists are attempting to appeal to people who watch TV!
The greatest inventors in history likely wouldn't consider themselves "creators" of their inventions so much as "observers" of the natural world. Prior to the past century (thank you Nietzche) inventors and artists played a similar role (look at Da Vinci, who is considered to be both), in that their job wasn't to "create" things, but rather to "mimic" the world they saw, and seek ways to perfect it.
Now, keeping value judgements out of this (I'm not claiming they're better than we are per se), it seems to me to be more effective the way things used to be done. Perhaps our "progressive" mindset has forgotten some important lessons.

Thus, under this classification, most of these technology demonstrators are actually drones. They act as we tell them to act, and that's all they are capable of. Real robotics research, on the other hand, is more about artificial intelligence and autonomous goal achievement. Thus, though they can't walk, talk, and shake our hands, the machines entered in the DARPA Grand Challenge are more robots than these walking contraptions are.

I've told people for years that "AI" has been going the wrong direction. Developments like Deep Blue only helped to feed this (incorrect) belief that "intelligence" very directly equates to "computational ability." This is so wrong, and so obviously wrong.
Look at your average toddler (I have one at home to study - get your own). Does this child compute the millions of different parameters required to negotiate a different path up, down, around, through, under their environment every time they want to go play with their train set? Nope. The kid throws his foot in front of him, in a basically "informed guess" that's partially learned, partially innate. He learns to then simply go along with whatever comes out. Swing your center of gravity to one side, and your body figures out how to deal with it in real time, based on an "informed guess" - no laborious computation as to trajectories or kinetics. Just some general goals and a shove in the right direction.
I call this concept "profoundly intuitive logic." Yes, we can be extremely rational about every motion, every activity, every human endeavour, but you'll find it's a lot easier to "just wing it." That's true intelligence.

What robot meant originally? You mean "worker" in Czech? From the play?
In the robotics lab where I worked, the generally accepted definition for robot was "a programmable source of work," where work is in the physics sense of forces and movement. This definition will include most things you would think of as robots, but would also include devices such as automatic breadmakers. I find this a useful, if broad, definition.
Industrial robots have a long history and are generally accepted to be robots (at least by people who call themselves roboticists). Industrial robots are often autonomous, but rarely make decisions or have AI of any kind. (An industrial robot is a more general device than special purpose automation. The manufacturing line for pampers will be automated, but does not necessarily contain robots.)
Under the above definition, the passive walkers described in the Science paper would not be considered robots because they are not programmable. But the powered walkers (basically a passive walker with an actuator or two added somewhere) would indeed be considered robots.

If you are doing a real flyer, you would need huge wings as the atmospere is thiiiinnnn. But, use some helium/hydrogen in a collapsiable wing, combined with small rockets, it is very doable. Think in terms of a vtol aircraft such as the british harrier. Small wings.
Of course, a small number of ballons with small camera might produce some very intersting results. While we would not have good control over where they went, they would be close enough to the surface to take some very good pix that could be relayed from sat. above.. These ballons could then be landed with small amounts of equipment, but obviously, this is more of a serindipity approach to checking the surface.
I prefer the "u" in honour as it seems to be missing these days.
[Meeting log]
What we need is a little engineering brainstorm:
Let's define the general tasks of robot creator regarding movement:
1) Do we want to make it be human-friendly?
2) Do we want to make it suitable for movement in the city?
3) Do we want to make it move off-road?
4) Do we want it to climb Mount Everest even faster than humans?
Well, for 1) and 2) two legs are sufficient. Wheels/belts can do the job too. And control electronic can be quite simple (compared to 3,4)
In order to 3) and 4), we need to equip the robot with another limbs. Hands could be useful for this purpose.
Six foot, beetle-like machine, could do the job. But it doesn't satisfy 1).
So, the consideration will be: machines in contact with humans shall be equipped with legs and hands.
Sixlegged machines will be sent to Mars to investigate. And for mountain climbing. And to attend on GWB.
[End of log]
I was pondering robotics the other day, and came to the conclusion that, for the most part, we're going at it all wrong.
I was thinking that we should instead build each limb as a seperate subsystem, with the nessesary computing equipment built into the limb, along with the power supply.
One thing about all ambulatory animals, is that the weight is equally distributed throughout the body. It isn't about figuring out how to balance all the weight in a torso, it's about using weight to act as counterweights, along with sensing the nessesary force needed to move each of those weights.
Another part of it is reflex movement. We think of it as simple because we learned how to do it with almost no effort long before basic skills. For a computer, this is something that requires a huge amount of processing time.
However, a "main brain" that has to interpret data from multiple individual "sub brains" would have an easier time, since the sub brains would process specialized data.
An arm would process just the data for that arm, a leg would process just the data for that leg, etc. Instead of the main brain having to process reams of data from every sensor on the body, it would have to only process the sub brains' inputs. Consider it as a biological analogy for USB.

Wow science, that's great, but what if one of these falling robots falls on your dog? Then what?
Avoiding things is the one advantage to calculated robot moving, unless they make them able to avoid things as they fall, but then they potentially will stumble into something else valuable.
"Spider robots", "Robots using gravity to walk", "Human robots on mars". We really have no clue. In years to come, people will be looking back at discussions like this and laughing. We are just at the beginning of robotics, yet here we are speculating about the future - probably totally incorrectly. Remember in your history class you used to read about people hundreds of years ago talking about science and their predictions of the future? Remember how ridiculous they sounded?

Specialization is for insects. - Robert A. Heinlein
If computer intelligence is realized, it can improve itself by writing programs. Now strip away all the baggage like butcher a hog and cook a tasty meal, and reduce the idea to a computer that can program a computer. This is a basic element of intelligence: a being that can formulate and execute a virtually unlimited number of sequences of instructions that take advantage of a fairly powerful machinery or computational mechanism, including the ability to control with some precision and accuracty the being's output of such sequences.
A neural net can be built to exhibit this behavior. With enough nodes the network can produce instructions from an instruction set. Add more neurons and tweak to acquire a machine that outputs a certain useful programs for certain inputs. Use a neural net to perform a feedback function by evaluating programs according to goal achievement, resource usage, timeliness, etc.
Neural networks are useful for handling large inputs such as sensory data as well as information written in a language. So build a feedforward contraption of neural nets that produce programs and a feedback set of neural nets to evaluate programs. This network can be scaled up and adjusted. Add CPUs to execute the programs. Furthermore, allow the programs to access the neural nets via the inputs and the adjustable weights. This is a readily achievable plan for a neural net that has the potential to improve itself via computer programming.
