Dynamixels And Herkulex.Again

Love digging up a horse and beating it again? Well fellas I'm here to help you out!

Lets start another up to date discussion about the use of, and the support of, Dynamixels and the HerkuleX line of professional servos. I'm moving up a level with some upcoming projects and steering away from the hobby style servos. I've spent days researching, using geared stepper motors, geared DC motors as servos and have come back full circle to serial servos. Due in part, by all the unknowns and unreliability associated with creating a servo from scratch.

Tell me about your success and failures of using the Dynamixel and HerkuleX servos with EZB. Please be detailed in your experience and add something to what is already written in the prior threads about subject. What needs to change/improve for better support? Perhaps this is adding to existing plugins or writing new ones? Speaking of plug ins (this is probably another topic), but i wonder if there would be more incentive to create plug ins if there was a pay for development? Like how the app store works? Just a thought there.

I really believe in everything EZ robot and want to continue using the products, because well its so EZ and the results are amazing. I'm well aware the majority of sales is in the education market for EZ Robot and therefore guides their company. But, how can we work together as a group to build support for the next level of servos and professional robotics? And ask ourselves what is the motivation to do so?

@kamaroman68 please read my previous post

Dj Sures I have no reason to update the plug in I have. After spending the money to fix the issue and getting it to work I'd rather not mess with it and have to come up with another work around when it doesn't work. Again I am no longer using the ax 12a servos so no need. Thanks

@DJ, I downloaded the plug and looking around at the controls. I pressed the "?" for global max servo positions and the *note is cut off...but i think i get the gist. If you choose 720 thats going to make for a loooonnnggg drop down to choose positions. Just double checking that was the complete note.

As for protocol 1 and 2, does this relate to ttl and Rs-485 protocols?

The protocol relates to the dynamixel servo. I'm not certain about what models use what protocols.

OK I'll poke around when the servo arrive! Thanks.

@Dj,

Dynamixels come in two versions the TTL version (3 wire) and the RS-485 Ver (4 wire). On the plug in description you have "Each Dynamixel servo contains a microprocessor. The microprocessor is told what position to move the servo into over a RS485 protocol."

I just want to be clear on my understanding.

I don't know very much about those servos. So far you know more than me.

What type of dynamixel do you have to test the plug with with? the Ax-12?
