How about an affordable 6 servo biped!

@Harry Mueller

Hi Jim,

Congratulations on taking SixPac in this wonderful new direction. It offers a great option for those not wanting to do the frame fabrication.

Thanks also for validating that the robot can be built with cheap servos. I’ve had some people question whether SixPac could be built for under $100 and I think you’ve shown, with a reasonably well-populated parts box, that is certainly possible.

Now I wonder if the HS-422s could handle an 8 servo biped?

Regards, Harry

Hi Harry! Nice to meet you.
I have been having a great time watching this robot design evolve with the SES parts. I have been amazed at how much can be done with only 6 servos. We plan to add a few more videos today.

I did quite a bit of internet searching for the original Tao-Pie-Pie and found very little information about it. Do you have any links with images, and more information on the programming? Thanks!

Hi Jim, nice to meet you too! I’ve spent quite a bit of time on your website marveling about your projects and eagerly waiting for new ones. You’ve done a great job of making robotics accessible to the average hobbyist.

Unfortunately, there just isn’t too much infromation available on Tao-Pie-Pie. Most of what is available can be found on the U of M autonomous agents lab site: avocet.cs.umanitoba.ca/ under “humanoid robots”.

I also have a few pictures and a paper that Sara wrote that I can forward if you’ll provide me with an email address that can handle attachments.

Regards, Harry

Hey all, I have 5 new videos up of the 6 servo biped on the website. Go check 'em out, eh?

this thing just keeps on getting cooler and cooler

[chunga]

those aluminum channels interest me, i saw them on the main site today and you can probably do a lot of stuff with them, make legs wider on biped, cool things jim and beth

Wow! Imprssed by the simplicity of it all Jim & Harry!

I guess if you are using the visual sequencer then you are hard coding each of the servo positions for each of the moves? how difficult are you finding this particularly to get the robot to balance!?

Thanks

Hey John!

The cool part of the Sequencer is the calibration. You set the end stops, and their associated angles, and forget about pulses. You are working with angles from that point forward. So shifting the weight is a simple matter of changing one ankle to -17° and the other to +17°. Also due to the calibration feature other builders using the same physical build can use our examples. The Sequencer is so intuitive that my 16 year old son programmed all the moves in the videos with litterally no assistance. Just the manual…

The ability to balance is very good, even though it’s using 422 servos. We will be building one up with more powerful servos so it can jump and do other crazy things.

Oh, the goal is to build a library of moves into a Basic Atom program to replace the PC. Then we can add sensors etc. This is really getting fun.

but Jim your 16 year old son is YOUR son, and you own a robot store, come on you cant tell me that quite a bit of information hasn’t leaked on to him

Well believe it or not, robotics is not is primary interest, and he has never used the program before.

ok, ill just shut up now

For X-Mas I got the makings of a biped (I know, I’m spoiled!) I have 10 5645’s and all the brackets. I recently started to build a tracked robot… But since I won’t be using all of the servo’s and brackets I might have to build one of these 8)

I’m 16 also with no prior experience, so we’ll see how easy it is for me to use the Visual Seq!

I just watched the balancing video. HOLY CRAP BATMAN! I like the assult on the water bottle too.

Yeah, you can almost build this little guy from the parts you already have. The little “U” channel parts just came in today. We will have them on the website as soon as we find a place to put them.
Funny thing is this robot could have been made along time ago with the parts we sell, and a little bit of fabrication. We just needed a little nudge of inspiration to know it would work.

[malatory]

Like the little guy … looking at him makes me want to take apart my hex pod adn have him untill I have the rest of the parts …

maybe I will just order some feet along with my next order … (GRIN)

I’m going to build the legs tonight and possibly jerry rig a U channel tommorrow.

If’n ya want to reduce the amount of jerry riggin…

I know this maybe a greedy side of me … defently the lazy side…

do you have the save SSC-32 programs that let the little guy move?? at lest examples of the ones you have movies for.

as I ordered more parts for the Hex pod and feet… I was thinking about playing around with the programming this weekend.

Nah, I got her a fixed up, all nice and purty I took two multipurpose brackets, put them on top of the legs and secured it with a piece of aluminum angle iron. Everything is all nice and secure. Wish my computer would let me upload pictures If someone wants to host a picture, I could post my little guy.

Now for a stupid question. Could I use the Mini Atom alone, without the help of the SSC-32? Or do I have to hook both up if I want it to walk by itself? And which jumpers do I install on the Mini Atom?

We can surely export the projects. I will have it posted later today.

Hmmm… must be an alloy of some sort.

Yes you can certainly do it without the SSC-32, but it will be more difficult. The biggest problem is there is no easy way to make the moves coordinated, (start and stop at the same time). That’s the power of the SSC-32.
