I want to connect the dynamixel AX-64 motor with the PC, however, when I follow the tutorials and create a meta controller, I come across the following question.
I start the controller using the following command.
roslaunch my_dynamixel_tutorial start_meta_controller.launch
And the error is:
... logging to /home/acer/.ros/log/63b699b2-a98e-11e7-b094-28e34739f5b2/roslaunch-acer-ubuntu-5609.log
Checking log directory for disk usage. This may take awhile.
Press Ctrl-C to interrupt
