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?
Hmm, Still only 90 degrees of movement, yes updated to version 12.
In all honesty I took the servos out of the box and used ARC utilities to address the servo ID. I don't know of any other software reset with these servos. I will see if I can google anything about resetting these types of servos. Thanks again!
So in further troubleshooting I removed the mx64t servo addressed as v5.
I reinstalled the other mx64t servo addressed as v2. To clarify I physically connected the second servo to the buss and took the v5 servo off the buss. I will now say that the second servo is working. But when I put 180 in the servo actually goes a full 360.
I need to look into finding software to reset a servo or something, as mentioned by DJ in an above post. Im glad to see some of this being resolved. Thanks very much. I will let you know my further progress.
360 is most likely correct if that is the full resolution of the servo. For example, it may be 4096 steps of 360 degree rotation. The AX-12 servos i believe are 300 degrees at 1024 steps.
So 180 may be 360 degrees on a third party servo-motor.
However, i'm not sure what else i can do at this point for trouble shooting. I believe your results, however i'm unsure what could be causing them as i see the correct values being transmitted to the servo during testing.
In my tests... If Max Position = 1024, then 180 = 1024. If Max Position = 4096, then 180 = 4096.
See if there is a factory reset or something that could be causing the limited range.
Yup , Im starting to believe there is either something wrong with the servo or maybe there is another piece of software to modify these things. Thanks again for all your help.
I'll google and see what there could be. I don't see a "factory reset" option in the command protocol list.
I found this: http://support.robotis.com/en/software/roboplus/roboplus_manager/testandconfigure/dynamixel/actuator/roboplus_manager_anglelimit.htm
Do you have software to configure the servos?
I get my dynamixel on tuesday. I'll let you know what I get straight out of the box.
All good progress so far.
DJ yes I just saw that. It also appears I need to use some kind of adapter called a usb2dynamixel adapter in order to talk to that servo. I don't have the adapter I will have to order one. These servos are a PITA! Gosh I hope there worth it.
Just found the software as well. Downloaded it. Of course it needs to be connected to a servo to step thru the setup steps. Anyways thanks again, it looks like this has been cleared up on the ez robot side of things. I will update as I get more working and when I get an adapter.
Will you should be able to use EZ robot directly without the arbotix controller. I have confirmed it with one of my servos. Now Im sure for whatever reason the other servos fault are my own. Will keep everyone updated.
