REQUIRED process [open_manipulator_dynamixel_controller-2] has died!

[MorrisJeong]

I just tried to operate open manipulator system by using two motor(MX-106).
When I launch that code, the following error occur.

roslaunch open_manipulator_dynamixel_ctrl dynamixel_controller.launch

I already let the USB accss allow, but it is not working too.
What would I do to solve this error??

started roslaunch server http://localhost:*****/

Hello :)

Which Dynamixel do you used?
If you used Dynamixel is controlled by protocol 1.0, you need to change some function in controller.
Please refer #10 issues

Thanks

[MorrisJeong]

I used MX-106 motors and the protocol version of those is 2.0. And I updated all the motors.
Is there anything else I can do for solving this problem?

[routiful]

Which number did you set ID to dynamixel?

[MorrisJeong]

I have two motors. And I set the ID to one and two separately.

[routiful]

Would you mind trying to connect Dynamixel by Dynamixel-workbench??

It is more convenient for debugging

Thanks
Darby

Hi :)

you have to give permission to open port. Please type below commands and relaunch it.

$ sudo chmod a+rw /dev/ttyUSB0

[unverciftci]

Hi, I tried sudo chmod a+rw /dev/ttyUSB0 but it did not work.

You can search connected usb port in your laptop.
Please check it and try again.

$ ls /dev
