Revision history [back]

Hi @Rizqa,

If you are using the current version of the robotis package from here http://code.google.com/p/gt-ros-pkg/source/browse/ repo=hrl#git%2Fhrl_hardware_drivers%2Frobotis, then it appears that it is no longer reading ROS parameters to set the baudrate and port. The defaults are 57600 for baudrate and /dev/ttyUSB0 for the port. You probably need to change the baudrate to 1000000 which you can do by editing the lib_robotis.py file:

$ roscd robotis/src/robotis

Then edit the file lib_robotis.py and change the baud rate to 1000000. This worked for me.
