  1. Include a full description of the issue.
    I’m having issue with read angles from each motor.
    I tried to check each angle on the Dynamixel Wizard 2.0, it’s almost 0 degree.
    However I executed the ROS program, its error occured.

If you are familiar with this OpenMANIPULATOR-X or XM430-W350, Dynamixel Wizard 2.0 please help me!
