No, Nomad, you actually sounded like a voice of reasion. You mentioned that Chris probably no ill intent. It actually was hardware that put Chris's picutre on the top. We as forum members and responders to a thread have no control over what goes there.

For the record, ignorance is not a bad word. I just means that the person does not know.

I really like the videos of this robot! Keep them coming Smile It will be a nice robot to feature in one of our upcoming videos. Thanks for sharing!

I know this is an old posting however I am wanting to build a hex as well and in looking at yours and reading this I have to wonder if you ran into the same issue I did. I began trying to build a phoenix type hexapod bit used the same framework you did with the same mg996r servos and ran into complications with a cheap lobot controller and servos that kept "going out", burning out, or generally broke. So I am wondering if going with the EXROBOT microcontroller and software would resolve all of these issue I keep running into. It appears that this controller can not only run the mg996r servos but even dynamixel! and can handle more than enough servos for a 3 or possibly 4 DOF per leg hex design? Is it really as simple as connecting my servos to the microcontroller, calibrating or "centering" the servos, and control or program from the software? no debugging, compiling, just connect and control? also can six be built with 3dof per leg? if I am correct please tell me as I will dive right in if I am wrong please correct me. sorry so long but anxious to find out. thank you for your time and hopefully a reply on this years old thread.

Legren,
I’m currently rebuilding my hexapod using the HDD Servos and EZB controller, as I complete disassembled it to using the Servos and EZB when I started my InMoov build.
One of the major issues I had was because the framework was ALL metal and with the 20 Servos and 2 batteries the hexapod was extremely heavy and the Servos would buzz like mad in certain hold positions ( normal characteristics of MG996R and most other servos ).

With the HDD Servos there’s no buzzing at all, and are fantastic servos.

I’ll post pics and video once completed.

Chris.

Legren, your questions are correct. Simply connect up to 24 servos directly to the ezb and programming is fun, not compiling and stuff. Add camera and speech and joysticks. Even make a mobile app for your robot without having to compile etc. Smile

Thank you both for the replies. My SIX is on it's way to me (I expect it to arrive day after tomorrow!) and based on your replies I'm excited and expect I'll be ordering an additional EZB as well. I have lots of extra stuff laying around I could put to use if the ezb is as I now expect! Again thank you both! Oh and does six require a ultra sonic distance sensor for true object tracking or is it only to improve tracking?

#29

Distance sensor is for detecting distance - nothing to do with objects. For object tracking, the camera is used. You can find out more using The Robot Program. There's plenty of great Activities at The Robot Program in the learn section.

Is there a program or script for a hexapod with 3dof for 18 servos controlling the legs? Or even for SIX with an extra Servo per leg?
