Humanoid Robot KHR-1 SDK Released

timothy posted more than 9 years ago | from the meet-your-boss dept.

Robotics 98

ls129 writes "KHR-1, the Japanese Robo-One humanoid robot kit from Kondo (previously mentioned here), is finally open for creative software development. The first unofficial implementation of the PC-controller API has just been posted. Using the SDK, the 17 servos that give the robot its mobility can be remote controlled by the PC via WiFi or bluetooth, and their current position can be retrieved several times per second. This unique feature will allow robot fans to go beyond simple performance of motion sequences or low-level gyro-based motion correction and develop algorithms that involve feedback control and AI." Update: 04/05 16:59 GMT by T : As originally posted, I erroneously changed the robot's nationality from Japanese to Korean; that was a boo-boo; the linked site with an English translation is Korean, but the robot itself is Japanese. Apologies to the submitter, who had it right.

Sorry! There are no comments related to the filter you selected.

Re:Hang on, AI? (3, Insightful)

MBGMorden (803437) | more than 9 years ago | (#12142816)

I think it's a matter of processing power. Serious AI is going to take serious processing power. No little robot will be able to carry the leve of equipment needed to "think" on its own. So the solution (for now anyways) is to setup the software on some super computer (or at least something significantly more powerful than the robot's internal facilities) and then send interaction commands to the body via a wireless link.


Hopefully in the future suitable devices will shrink down to a level that they can fit inside a human sized robot.

Re:Hang on, AI? (2, Interesting)

ls129 (831328) | more than 9 years ago | (#12142836)

Congratulations on posting the first non-troll comment!

The AI-enabling feature is the position feedback that you can get from the servos. In order to create AI you need a feedback loop involving getting sensor data and updating servo positions repeatedly.

Normal RC-servos were designed to be embedded in a RC-car or RC-plane and controled by a human. In this case the feedback loop is acheived by the human seeing what the car is doing and updating the direction with his joystick.

For an autonomous robot to work, the cpu needs to be fed with lots of sensor data at high refresh rates. Hence this humanoid has the potential of becoming autonomous.

AI Has Been Solved (2, Informative)

Mentifex (187202) | more than 9 years ago | (#12143645)


The news [advogato.org] has recently been announced -- just in time for the emergence of AI-ready robots -- that the sideways integration of sensory input with a conceptual mindgrid is the solution to artificial intelligence.

The solution to AI qua problem -- qua grand challenge to humanity -- exists at first in theory [sourceforge.net] only.

The Association for Computing Machinery has reported in ACM Sigplan Notices 33(12):25-31 [acm.org] (1998) and in ACM Sigplan Notices 39(12):11-16 [acm.org] (2004) on progress in implementing the AI solution as open-source AI software [sourceforge.net] evolving into Mind.Forth [sourceforge.net] for robots. There is an implicit contest involved here of who can keep the date-stamped robot AI Mind [sourceforge.net] running the longest, as if for the Guiness Book of World Records. Since Mentifex AI is in the public domain, programmers are free to customize special AI Minds in any programming language and to offer their artificial intelligence for sale on eBay [ebay.com] in the Computers and Networking [ebay.com] software marketplace.

Please do not point to the primitive Mentifex software [sourceforge.net] as proof that the claim of an AI solution [sourceforge.net] is false. The only claim made here is that AI has been solved in theory [sourceforge.net] , not yet (please stand by) successfully implemented in software or hardware. The Artificial General Intelligence Research Institute (AGIRI) [agiri.org] is creating powerful Novamente [del.icio.us] software but is handicapped for lack of funding and for disregard of the Mentifex AI theory. Mentifex has a secret plan to locate funding for AGIRI [agiri.org] if the AGI team either hires Mentifex or agrees to implement [caltech.edu] the Theory of Cognitivity [sourceforge.net] .

Just another toy... (2, Insightful)

zappepcs (820751) | more than 9 years ago | (#12143700)

The 17 servos in this robot use a LOT of battery. Add a wireless card to that and the joy of *using* this robot will only last a few minutes. Especially if that battery has to also power the remote video link. Its not big enough to carry lots of batteries. The act of remotely controlling a robot is not new, nor is it proprietary. There are dozens of servo controllers on the market that can be controlled using simple serial commands. The clever home robotics hobbyist can buy all they need to replicate this robot in the good old US of A. There are some that are building their own. http://www.sorobotics.org/dgates/samm.html [sorobotics.org] It may be cute, or cool to watch, but the gizmos inside it are ordinary, and can be replicated almost anywhere. There is nothing to get excited about until robots are doing something useful for mankind in general. For example: yard work, harvesting crops, mining on other planets etc.

Re:Just another toy... (1)

ls129 (831328) | more than 9 years ago | (#12143861)

The robot can last up to 25 minutes with a NiCD 600MaH battery.

What makes this robot unique is the use of the Kondo ICS-KRS series of servo motors that provide feedback not just PWM-based position control. Many hobby roboteers would be glad to learn about dozens of servos on the market that give you position feedback without having to hack the heck out of the servos and possibly insert a tiny15 [atmel.com] into the gearbox in order to get some position feedback.
There are a couple of Korean companies that make servos that are communicable via serial, these are Robotis and Megarobotics. Probably all other servos on the market are one-way controled by PWM.

Re:Just another toy... (1)

zappepcs (820751) | more than 9 years ago | (#12144466)

Ok, perhaps the servos are not truly ordinary, in as much as they have position feedback built in, but that is still not something that is impossible to achieve in other ways. In truth, to get a standard servo in a place where it has not or cannot move to the position commanded by PWM is not very easy at all. Digital servos have a good deal of muscle, and a robot in the toy size range is seldom, if ever, going to push the servo that hard. Its an application where absolute position information is not required to achieve the goal.

The Robotis servo type systems are apparently made by hand with maxon motors in them. When such devices are mass produced (read made cheaper) they you just might see all kinds of robots. If I could afford the 450-500 dollars for digital servos, I'd have already added an articulated arm to my robot. That has nothing to do with the creations from Korea or anywhere else.

Octoped robots use as many as 24 servos that are synchronized to allow the arachnid like robot to walk, run etc. The only difference is that a humanoid robot just has a higher coolness factor.

Contrary to the "mainstream" approach of actuating every joint with a complex control system, the authors describe three robots that achieve very natural human-like gaits using far fewer actuators and much simpler control principles (one of them using adaptive learning). Not only are these robots far simpler to control, but they typically require only about a tenth of the energy of designs that attempt to actuate every joint (e.g., knees). I'll speculate that this passive/dynamic approach is going to dominate in the future.

So far all those robots do is walk forward at one speed. To do more (like stop, or turn, or climb stairs, or get up after they fall) they will eventually need joint control. What is really necessary is a servo with a clutch. Or artificial muscle. Then robots could harness passive dynamics but still be able to exercise control when necessary.

What'd he do to deserve that? Or was it just a layoff because his robot duties were outsourced to India? :-)

Feedback claims dubious (2, Insightful)

Unmodified hobby servos do not expose the position data without cracking them open and reading the internal pot. Looking at the API, I'm guessing it's simply remembering the last positions you told it to move to and regurgitating them.

I'm working on a project that sort of does what this is claiming to do by providing this feedback by way of current sensing.

I dont think the RCB-1 controler regurgitates the previous position. The servos really do have a signaling protocol that allows the controler to retrieve the current position.
Check out the PDF called "ICS Servo Special Protocol" here: http://robosavvy.com/Support/2 [robosavvy.com]
This will be validated experimentally soon.

I know someone who has done a similar project developing interesting gaits that utilize current AND position feedback form the servos. http://www.mundobot.com/projects/melanie/v2/enmela nie2.htm [mundobot.com]

I stand corrected. These servos are unsual and very cool!

Most people in-the-know realize that traditional RC hobby servos are practically useless for serious robotics projects. They're underpowered, inprecise, and unreliable. This is why several companies such as Kondo and Megarobotics (both Japanese IIRC) have designed special digital servos that are more powerful, easier to mount, and double as sensors using networked bus protocols. If you're into robotics, don't waste any more money on obsolete RC servos.

But, rc car servos are cheap as hell and available in high torque and high speed versions. If you can report the position cheaply somehow, then they're not bad little devices. If you were building a snake robot or something I'd think that RC servos would be a VERY good idea, because they're cheap as hell. For very fine control, I'd probably want your digital servos.

How small do the digital servos get?

It should be noted that this is a closed, binary, Windows-only dll, which may even damage your $1500 robot. I don't want to sound zealous, but no serious robotist should be using Windows. Wake me when anyone can compile it under Linux.

Use this library at your own risk. There is no guarantee this software would work at all in your system or your robot. Your robot might be damaged. ... This is a library for controlling the KHR-1 RCB boards using the serial link from a PC under Windows.

oh well, they all look the same (0)
