Joint State problem in XM430-W210
2020-11-20 16:02:36 dudwns6717

I tried to control XM430-W210 motors in ROS. I followed workbench tutorials.(https://emanual.robotis.com/docs/en/software/dynamixel/dynamixel_workbench/)


But when I control the motors with angular velocity,  cmd_vel (topic) there are two errors.

1) The motors move, but these messages show in the terminal


[TxRxResult] There is no status packet!

[ERROR] [1605853540.936610384]: groupSyncRead getdata failed

[ERROR] [1605853540.936625298]: groupSyncRead getdata failed

[ERROR] [1605853540.936637595]: groupSyncRead getdata failed

2) Problem with the jointstate topic

Doesn't show the correct value of the /dynamixel_workbench/joint_states topic, it means position, velocity and effort of the motor, the results remain constant, different when I use AX-12 motors, is working good.


 How can solve the problem with XM430-W210?
