How About A Walk-Off Competition

Hey Brothas and sister,

I would love to see and learn the best method used with the EZ-B for biped motion. Measure could be speed and stability.

Here's an hour MIT presentation on dynamic feedback for bipeds: MIT Dynamic Biped Feedback

Here's the results of a google search which shows there's lots of room for improvement. It seems the the EZ-B's speed and multiprocessing is a huge advantage over other platforms: Robotic Biped Search

With ARC Pro, your robot is not just a machine; it's your creative partner in the journey of technological exploration.


Here's a video of a biped competition:

Here's the most smooth I've found so far. It includes some of the physics involved:


Hi @BrainPaint Welcome to the forum!

I too am excited to see some new Bipedal walking concepts.

While there doesn't seem to be a "best" way out there, besides the way us humans walk, it is interesting to see what works better for speed and stability.

It seems like the suffle method works pretty good for speed but I like how the Titrus walked a little better as it was more true to life and seems more stable.


I agree about the 1:41 bot.

Here's one with pretty smooth movements with 3 servos per leg: I suspect it's using an IMU for stabilization:

Cheers, Bill


Jimmy? no imu - he's got 5 or 6 servos per leg. When jimmy received a little bit of attention a few months ago there were some articles. What Intel could do is add ez-b to jimmy, and bring the cost down with our existing software to make him affordable and manufacturable.

The easiest way to make an ez-robot walk is to use auto position, doesn't get any easier than that. Just make it...

Just add more Lever HDD Servo-motor's to JD if that's what you're going for. Clip them together and there you go. JD is $500, those other robots are well over $5,000. You can make JD walk like them for an additional few servos, which only totals another $100. Still hundreds less.

Jimmy is $20,000 - but not available for purchase. If you'd like an expensive clumsy slow robot with limited programming ability, NAO is only $10,000

If you're looking at making a smooth walking robot with many degrees of freedom, simply buy more Lever HDD Servo-motor's, clip them together and make Auto Position frames.


Very cool DJ!

That would be sooooo cool having a $600 or $700 robot with near or superior functionality over these $10,000+ bots. Whoever does this first, with spandex clothes covering their wires, will quickly have trouble keeping up with the demand. I'd pay $1000 for one right now even with the gripper hands and naked. :)

Thanks mate,




anthony makes the end&top caps for the servo,they look like bioloid.

dj NAO v4.0 cost 8000 dollar now,but you can find a NAO v3.3 for some 3000 dollar. next year januari pepper comes out for sale 1400 euro 1.40 m tall+ a big included ipad.5 fingers each hand.
