AX-12/Arduino Hexapod Robot

Hi all, I’m pabloxid from Uruguay. This is my first post, maybe you have seen me in other robotic forums, where I was also showing my work.

I want to show my latest robot, it’s an hexapod made ​​with 18 AX-12 motors and an Arduino board. (Before this I had made ​​another hexapod, but it was very basic).

In the video itself you will find a description of it, but I’m preparing a more extensive documentation on my site (pablogindel.com).

Thanks for your interest

Greetings.

Nice job!

How do you communicate with the AX-12 servos from the ARduino (UNO?).

I understood it was a propitiatory interface.

Hi, Alan, thank you for your comment.

The Arduino is a Mega, with ATmega1280 inside. To communicate with the AX-12 servos, we developed an AX-12 Arduino library, which was, in the beginning, a version of the Arbotix one. From a hardware viewpoint, it simply uses ATmega’s USART interface, at 1Mb/s baudrate.

Here’s a link to the library page: pablogindel.com/2010/01/bibl … ara-ax-12/

Regards.

Found the library, although I could use an example.

Now I can play with my two samples, and not need to buy a drvier!

Thanks!

Hi again.

I updated my website, and posted the documentation of my project along with its sources:

The Shock-absorber idea is good!
