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.
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 .
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!!!
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.
[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. cgi.ebay.co.uk/10x-Hitec-Servo-M … 240%3A1318
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
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.
