I saw something very interesting on a spider last night!

Yes!

Nice illustrations. I see the extra two axis added between a pair of legs on one end of your ant. very clever! How’s it working for you?

Can you shift the CG enough to free up two front legs for use as arms? Being able to do this will allow the new “arms” to pick up items, something I’m working on.

This project is old and now unfortunately closed but it seemed to work ok, mechanically.

the whole front section lifts up, lifting both front legs at the same time but still allowing them to manipulate
independently and also the middle legs have an added servo closer to the body giving them a 4th DOF!
See last photo. Note: servos for chassis not populated here.

The legs look way long for normal servos to operate, particularly servos close to the body.

Hi,

I understand what your saying Alan, very interesting about the “swept” idea! Did you made any sketches of your ideas?

Wow Innerbreed, I’m always amazed by your ideas! Your ant looks awesome. But as Zoomkat mentioned this construction is pretty demanding when it comes to servo torque. Did you ever made it walk, any videos? And again a real challenge when it comes to the kinematics :wink: .

there is a vid but unfortinatly its the only one and it was a test…
youtube.com/watch?v=SemRLYGA … annel_page

this is using 475’s so i never pushed it to its max.
you can see when the legs lift up that the body drops due to the weight!

I designed this robot with the intention of never building it but i got ahead of my self and built it. luckly. id like someone to adapt this idea.

your right about the chassis part, maybe it wouldnt works well but this can be improved on!

just an idea id like to throw in on this topic on adjustable body design… maybe this is a good example on how not to do it. …share, use, improve.-thanks zan, i must stop using your sig!!!

Thanks for sharing your video Innerbreed!
Looking good 8)

Hi KÃ¥re, guys,

I had started to design a new bracket and body, but didn’t get any further. I got caught up in the Micromouse project that our local club was starting.

It seems you can’t just design a simple body, you have to design a dual channel PWM controller, a gear system, and a new main processor as well as a very compact body! But it is an enjoyable project!

How’s your quad coming along? I recall you had a very extensive 4DOF, (5DOF?) leg design. I wouldn’t mind studying more of your project.

Best regards,

Alan KM6VV

Very innovating design Innerbreed! I’m sorry to hear that you’ve ended the project! IK would be hard though 8)

LOL, No problem! I’m always happy to meet people who are willing to share ideas!

Innerbreed,

Why did you stop working on your antartic?

was it just too big for the servos to hold it?

–Aaron

yeah i couldnt afford to complete the build at the time! :frowning:
plus i then bumped my head and got a new idea so i needed the hardware for another project!

Oh, seems like an original enough of an idea it would be quite different to see it walk around or do whatever you wanted it to do really…

here is some inspiration!

… I think my phoenix got a little too close and look what happened when I came back

http://img8.imageshack.us/img8/5051/robot2.jpg

that’s the last time I leave my ideas around. I was just about to name the thing like dolebot or something… scratch that.

:open_mouth:

LOL

:open_mouth:

… I’m sure everyone has a pile of servo horn’s and arm’s when they order servo’s… can anyone think of anything useful to do with these things?..

One thing that caught my eye was Xan used them for his Phoenix rather then cut out plastic leg’s he used 3 servo arm’s and screwed them together…

so besides that anyone got any ideas? I pretty much have 18 of them of various plastic bits…

[size=200]eBay[/size]…sell them. i always sell these bits off in bulk or single packs. i find that the servo mounting hardware kits sell well. currently selling 40x Grommets (black rubber) 40x Bushings (brass colored) 40x Screws.

lol you’re kidding me. I have like 50k of those stupid things. lol

so you dont want anymore then? can i tempt you??? :laughing:

haha shipping to the UK would kill the profit.

Jim,

Just start adding them into packages of stuff people buy from you and they will be scratching their heads trying to figure out where the the parts go in the robot kits they order :stuck_out_tongue:

Christmas decorations? Hitech servo horns hanging on the pine trees?

put them in a box and forget about them, I guess good enough as anything.

:smiley: :open_mouth: [size=150]Yeah![/size] :open_mouth: :smiley:

Maybe you could use the servo arms for some extra longer legs. 8)
