Current position with Dynamixel servomotor AX12
Hi friends
I am working with Dynamixel servomotor A12 and ROS fuerte, I need to get a pan and tilt and when I do transforms I need to know which is the current position of 2 motors.
I don't know if the easiest way is using topics or services, please can you help me? I have looking for information and reading wiki ros but I have not found an explain.
Thanks.
