Hello, right now i am doing my project which is a 3 d printed arm robot and connected to my laptop using USB2dynamixel. I want to control this robot using MoveIt, but everytime I want to launch the robot_state.launch, this error always comes up

[ERROR] [1551179662.216765]: bad callback: <function process at 0x7f2f64be3488>
Traceback (most recent call last):

File "/opt/ros/kinetic/lib/python2.7/dist-packages/rospy/", line 750, in _invoke_callback
File "/home/richard/robot_ws/src/dxl_tutorial/scripts/", line 37, in process
IndexError: list index out of range

I have already checked the, but it seems like there is nothing wrong there. Can somebody please give some advice? I am also new to ROS.
