can't move dynamixel using joint_state_publisher [closed]
Hi
I'm reading the book "Mastering ROS for Robotics Programming" and I'm trying use the end section of chapter 10 to move my own robotic arm with moveit! for about a week.
There is a problem: moveit! (joint_state_publisher node actually) can read dynamixels' position &.... as it subscribe the /state topics; but I can't command them to go to the goal positions.
Even when I launch joint_state_publisher with GUI, the GUI show the current position but it don't allow me to change motors' position. But I can do it by run a rostopic pub on the /command topic manually.
I can't understand where i'm wrong. Can you help me to solve the problem?
Thanks
