The New Asimo Robot
- leyfa 15y agoWhat's the state of the art in humanoid or multi-pedal robots in terms of robustness and flexibility of their movement and balance? I assume ASIMO isn't as stable and stress resistant as the robots of Boston Dynamics, for example http://www.bostondynamics.com/robot_petman.html http://www.bostondynamics.com/robot_petman.html
- abrimo 15y agoAsimo seems quite a bit more advanced overall than those robots. They are designed for quite specific purposes and domain - it's hard to tell but they also don't seem autonomous. With Asimo, Handa is going for a general purpose robot that can emulate a human while Boston Dynamic appears to be going for more specific military needs with things like BigDog.
- slug 15y agoFrom what I learned from a BD engineer, Japanese legged robotics use mostly static equilibrium in contrast with the (more advanced?) dynamic balancing of US and European robots. Asimo might look cute, but if you compare the gait of any of the popular MIT, Boston Dynamics or CMU robots to the Japanese, you soon notice that the latter don't look very natural or adequate to unpredictable terrain. https://secure.wikimedia.org/wikipedia/en/wiki/Robotics#Locomotion https://secure.wikimedia.org/wikipedia/en/wiki/Robotics#Loco...
- anigbrowl 15y agoThat's true enough, but only the military and EMS need robots that can instantly handle unfamiliar terrain. Meanwhile, the Japanese are most of the way towards a consumer product, since the interior of a building is highly predictable.
- FrojoS 15y agoGood point, but if you don't need to handle unstructured terrain, you might just as well put the robot on wheels. The humanoids robot Justin from DLR [1] for instance has an omnidirectional wheeled platform that even allows for adaptive foot print. The only current advantage for ASIMO that I see at the moment, is that it doesn't have to take the elevator but can use stairs. [1] Here is a good video from 2009 that shows that Justin is capable of the same tasks that Honda showed of today http://www.youtube.com/watch?v=ZPwpGpMoAxs http://www.youtube.com/watch?v=ZPwpGpMoAxs
- anigbrowl 15y agoQuite - and with 4 wheels, I imagine that stairs would be manageable for Justin as well.

- FrojoS 15y ago> with 4 wheels, I imagine that stairs would be manageable for Justin as well In theory yes, but not with the current design. > You might like this too: Yes, ABB's Frida looks impressive, but so far there seems to be very little information about the technical data. > I think US industrial/product designers are seriously underestimating the market for consumer-facing humanoid robots. There is rumor, that Rodney Brooks's Heartland Robotics http://www.heartlandrobotics.com/ http://www.heartlandrobotics.com/ will release something similar to Frida soon.
- tintin 15y agoRunning, jumping on one foot while turning 90 degrees. I think that is just remarkable stable. Take a look at this slowmo-footage: http://www.youtube.com/watch?v=Ifl55QShWfE http://www.youtube.com/watch?v=Ifl55QShWfE It looks like the legs are constantly adapting. But ofcourse this could be programmed.
- JabavuAdams 15y agoLook how low to the ground the foot is, though.

- hexagonc 15y agoAlthough the Boston Dynamics robots seem more fluid and may have more flexible and natural overall movement, the ASIMO seems more autonomous. I haven't seen any of the Boston Dynamics robots actually performing a task adaptively (other than adapting to terrain and pushes/kicks). PETMAN looks really interesting but until it is turned loose untethered, ASIMO wins the best android contest.
- FrojoS 15y agoBoston Dynamics robots like Big Dog use hydraulic actuators [1] which act somewhat like a spring and are hence very robust towards perturbations. They also have more power (= force*velocity). ASIMO in contrast uses an electric motor with a high ratio gear drive [2] that makes the robot very stiff and slow while allowing for high torques. This setup doesn't allow for backdrive and hence can't handle impacts well. I don't know about the new ASIMO legs but in the video you can still hear the screaming of the gears. [1] At least the orignal Raibert Hoppers at MIT also used pneumatic actuators http://www.ai.mit.edu/projects/leglab/robots/3D_hopper/3D_hopper.html http://www.ai.mit.edu/projects/leglab/robots/3D_hopper/3D_ho... [2] e.g. Harmonic Drives http://en.wikipedia.org/wiki/Harmonic_drive http://en.wikipedia.org/wiki/Harmonic_drive
- johnyzee 15y agoWow, amazing. This has come a long way since the worst demo ever: http://www.youtube.com/watch?v=ASoCJTYgYB0 http://www.youtube.com/watch?v=ASoCJTYgYB0 The way it manipulates stuff with the hands is very impressive, not to mention the 'understanding' required to pour liquid like that. Wonder how much of that was scripted.
- wofser 15y agoI'm glad they put the wall in-front of him. Must have been a horrific sight for the children. I also wonder how much was scripted. Take for example when he unscrewed the cork. Did he "feel" that the cork was loose or did a programmer instruct him to unscrew the cork 278 degrees?
- hexagonc 15y agoNow, all they need is for ASIMO to say: "glass. . . ice. . . gin. . ."
- JoeAltmaier 15y agoThat mincing gate pretty much precludes selling it for serious applications. Looks like a coolie carrying a rickshaw...
- mootothemax 15y agoExcuse me, but "mincing gate?" Mispelling of "gait" aside, is that really an appropriate comment to make in this day and age? I'm getting a bit bored of feeling like the HN inappropriateness police. If it's not sexism, it's homophobia... are we going to have a fun time of racism next?
- JabavuAdams 15y agoWhat are you talking about? I don't think "mincing" means what you think it means. http://oxforddictionaries.com/definition/mince http://oxforddictionaries.com/definition/mince
- mootothemax 15y agoWhat are you talking about? I don't think "mincing" means what you think it means. I'm going by the mix of results on Google: https://www.google.com/#sclient=psy-ab&hl=en&source=hp&q=%22mincing+gait%22&pbx=1&oq=%22mincing+gait%22&aq=f&aqi=g-v1&aql=&gs_sm=e&gs_upl=4356l5120l1l5365l2l2l0l0l0l0l118l234l0.2l2l0&bav=on.2,or.r_gc.r_pw.r_cp.,cf.osb&fp=f2e3640de917052c&biw=1366&bih=667 https://www.google.com/#sclient=psy-ab&hl=en&source=... Maybe it's a cultural thing; certainly in the UK at least, "mincer" or "mincing along" are definitely offensive.
- JabavuAdams 15y agoOk, interesting to know.
- tomlin 15y agoYou got all of that from his comment? Damn.

- bane 15y agoSomething that's always impressed me about Japanese robotics efforts is the level of polish in the efforts. Complete cases (skins) on the robots makes them feel much more advanced than the non-Japanese efforts I've seen. It's this thinking about industrial design, along with the awesome technology that makes something like ASIMO feel like an almost commercial off-the-shelf technology. I've like to know much more about the software functions of the robot as well, which sadly, they don't go into much during the demos.
- gerggerg 15y agoAlso they seem to find the time to make robots that do other things than help with military action.
- agumonkey 15y agountil this year ASIMO, japanese robots felt naive compared to what's been coming out of boston dynamics | big dog team (which are on the opposite of the 'off the shelf look' spectrum). The latter being awfully uncanny in the depth of balancing behavior combined with the human scale proportions.
- ck2 15y agoThe way it's knees are overly bent is kinda creepy to me, especially when it runs. But standing still it seems pleasant enough. Also they need to code some imperfection into it - the absolutely perfect hand movements, unscrewing the jar and pouring are too precise - make it warble a tiny bit like a human would, make it shake the container at the end to get the remainder out.
- khill 15y agoIt always looks to me like it's running to get to the nearest bathroom - or that it didn't quite make it in time.
- FrojoS 15y agoThe reason for this, is their control algorithm. It uses a inverse kinematic to compute the desired motor commands in the joints. When the legs are stretched out, it is in a singular position where the resulting motor gains would be infinite high.
- frankus 15y agoReminds me of a quote from the always incisive Karl Pilkington (to keep this family friendly, google "asimo karl pilkington").
- polshaw 15y ago"It walks like it shit itself" -Karl Pilkington HN isn't for kids, i don't think the family filter is required.
- rglover 15y agoI hate the way this thing runs, it's so...sneaky.
