AX12 serial servos and Arduino

Hi,

I have build a balancing robot based on Sparkfun 5DOF acc/gyro combo, Arduino and Parallax continuous servo. I had sofar mixed results and suspect the servos have to much backslash

I want to test the AX12 servos which are supposed to have reduced backslash Can someone point me to some Arduino code to run these very specific servos (serial communication) http://www.bioloid.info/tiki/tiki-index.php?page=AX-12+page

TIA Yves

WOW They look interesting servos ! Anyone know where I can get them in the UK ? and also a library would be useful ;) Can they rotate 360­ degrees continuously ?

ax-12 servo uk in google brings up a number of hits, this is the first:

ah, thanks I found that site (I think) and I thought it was in Canada! ::)

Hi myozone, the pricing in pounds is the giveaway ;)

BTW, you are closer to Canada then they are, I just had a look and see they are just down the hill from me :)

If you get those servos, please let us know how you get on with them.

Have fun!

Hi Mem, Just ‘looking’ at the moment :), Would nice for a precision pan and tilt head idea I have + other ideas - just needs a good library. I’m still learning C/C++ :smiley:

myozone: Yes the AX12 has built in continuous rotation feature w/o hardware hack

I have found theoritical discussion on Arduino/AX12 interface here: http://robosavvy.com/forum/viewtopic.php?t=1760&highlight=ax12+arduino but sofar no actual working code

As anybody developped some demo code to control AX12 from Arduino ??? :P

TIA yves

Thanks I'll have a look :)

Hi, I created a library for the Arduino can run these servos and I've only used the conventional serial hardware on the arduino. :P
