I'm an EZB user, and I'm trying to make a biped walking robot. I saw many ones , including EZB's JP, but most of them walk inclinating themselves by a very large, non human-like, and even ridiculuos amount to keep gravity center within foot area. I saw in internet some robots made by amateurs inclinating much less and walking in a more human way. Is there someone in the community who had such good results and can explain what's the secret to get good balance without ridiculos and unstable inclination, and what's the minimum number of DOFs required to make that robot?
Add jd's hips for additional dof: https://synthiam.com/Community/Revolution/EZBitDetails.aspx?guid=6c44caf3-98fb-4a3b-8074-9bde69585eec
No one has created a walk gait with the hips component yet. Hips are the missing piece that you are looking for, left out of most humanoids to keep cost down and maintain functionality. Good luck with your build! The Auto Position control will be your friend.
As for the balance of walking without hips. It's not a ridiculous or unstable amount. It's, as you said, center of gravity amount, which is calculated stable amount. The center of gravity amount is a calculated and tested figure to maintain center of gravity for stability of balancing. This is something you will experience during your build as well. It'll be a lot of work, but the Auto Position control will make it much easier
I know what you're attempting to convey, is that walking without hips isn't visually appealing.
Have fun!
I don't like walkers without hips ! I call that "awkward" walking. I'm attempting this difficult job because I know I have the help of the Auto Position controI ! I'm surprised no member has tried walking with hips yet. I saw many in youtube, walking well, (e.g."Robogames 2011 biped robot race") using, perhaps, "dynamic balance ", like humans, (i.e. stepping forward fast enough before falling ). But there I can get no help for this difficult job !
Someone has already made hips for JD by the way, if you didn't realize.
Check with @Nomad 6R I think he played with hips on Jd.
I don't know how he made out. he hasn't been around lately.
I never thought JD looked awkward at all.
For what he does and for the price...well it's one hell of a kit and there's nothing stopping you from expanding on that, maybe fit a new body to it, etc?
Your only limited by your imagination, keep looking at photos and videos on how they move and then you will suddenly 'Click'
I only clicked last night and my jaw dropped by what went through my mind...
hi all
i just order the new servo's HDD.hips and a backpack .
you can see i chifted the bracket a little side ways.he will get a backpack too. so it wil take some time ,waiting for parts.
OK Newagetomy, no doubt JP is a good and cost-effective kit. What I want to imitate is human-like walking, and no human inclines himself left and right by 45° while walking... Use of hip joints would improve walking quality, and I have already experimented that with a wooden structure and giant servos. But it's not so easy. I was looking for someone doing this , to share experience, but until now I found nobody in the community.
Hi, Nomad 6R, i'm waiting for your experience with a more human-like walking.
