error when try op3_manager with standard op3 about robotis-op3 HOT 23 CLOSED

Is it normal that model number was changed from 1000 to 1020 for all servos when i update firmware?

from robotis-op3.

Hi,

I think the opencr firmware has failed in updating the dxl firmware. Could you refer to the e-manual to recover the opencr firmware?

The rest of the questions will be answered after confirmation.

Dynamixels of OP3 are XM430-W350.
Model number 1020 is the correct value.
The model number can not be changed through firmware update.
Only recovery is possible.

I have already updated firmware on opencr more than 3 times, but from windows. I'll try to do this from linux (Done, nothing has changed). (already read this issue - #50). I've even rebuilt all op3, replaced opencr (to new one), restored nuc from image and then reinstalled and catkin_make all catkin_ws.

After linux is loaded, all servos are fixed in their current position (torque on). RGB near buttons and at front turned on with green light

Hi,

Did it work after rebuilt?
OPENCR looks good now.
Model number and firmware version, id, baud of OPENCR are fine.
If not, could you show me the log of op3_manager?

Hi, here it is
master.log
roslaunch-robotis-op3-4169.log
rosout.log
rosout-1-stdout.log
No, unfortunately it still does not work.

Hi,

I looked at your log and it still seems that OPENCR is not responding.
Would you like to test it with dxl_monitor?
There is a program called dxl_monitor in the example of Dynamixel.
After connecting to OP3 with ssh, please follow the instructions below to see if OPENCR responds properly.

• Installation method

  • build library
    $ cd ~ / catkin_ws / DynamixelSDK / c ++ / build / linux64
    $ make
    $ sudo make install

  • build dxl_monitor and run
    $ cd ~ / catkin_ws / DynamixelSDK / c ++ / example / dxl_monitor / linux64
    $ make
    $ ./dxl_monitor

  • test

    • Change baud
      [CMD] baud 2000000
    • ping test
      [CMD] ping 200

from robotis-op3.

Done, ping to opencr (id 200) failed

from robotis-op3.

I have tested with dxl_monitor from opencr in arduino Serial Monitor dxl bus, and it works well! Opencr without nuc succeed to ping, to write and read to XM430.

1.4.X core for opencr was the reason of this issue. Now i use 1.3.2 core and all works fine.
If it possible, i want to know whats the problem with core 1.4.X :)

Hi, @GramJr

I will check about this.
And if I know the exact cause, I'll let you know.

from robotis-op3.

@GramJr

I've found a problem related to UART DMA function.
It was added in 1.4.0, but I found that it was not applied to the OP3 example.

I will update this with other features and will release it within this week.
Sorry for the inconvenience. And thanks for giving me more debugging info :)

@OpusK
Ok, thanks. Can I ask some questions about OP3 by mail, which is listed in the profile?

from robotis-op3.

@GramJr

If possible, it would be nice for us and other users to leave the issue on GitHub.
But, if your question is difficult to address here, please ask me about OpenCR's Firmware and ask @ROBOTIS-Kayman for OP3's software.

@OpusK
Thank you!

@GramJr

I just released version 1.4.6 of OpenCR!

from robotis-op3.

hello guys, i have same problem here. i use u2d2->opencr -> dynamixel mx-64. when tried to ping opencr, it always fails. when i roslaunch op3_manager, always error. i have used op3 code in arduino ide. i hope you can response my problem. Thank you

Hi @AlfretzNehemia
The OP3 is designed specifically for DYNAMIXEL X series and does not compatible with MX series.
Thank you.

@AlfretzNehemia
You may try upgrading to MX-64(2.0) firmware via DYNAMIXEL Wizard 2.0.
MX series with Protocol 2.0 firmware is very similar to X series.
Also you'll need to make some modifications in the source such as OP3.robot file where specific DYNAMIXEL is defined.

In regard with the ping issue, please try searching the opencr issue page, for example, ROBOTIS-GIT/OpenCR#147

Thanks!
