No tf from some link to some link
I am new to ROS and I am working on OpenMANIPULATOR-X. Problems showed up as I try to use RViz. Error occurred to Robot Status showing No tf from some link to some link.
I know joint_state_publisher should be responsible for this and as I tapped command rostopic list, the topic joint_states is listed. The same happens to the node joint_state_publisher when I gave the command rosnode list.
However, when I input rosrun tf view_frames,I get a frame with only two links which indicates obviously that my joint_state_publisher is not working properly.
So I am really in need of someone who can help with this issue.
No tf from some link to some link.Just a quick note:
joint_state_publisherpublishesJointStatemsgs, it does not broadcast TF transforms. That'srobot_state_publisher's job.And actually, if you have a "robot driver" node, I would not expect a
joint_state_publisherinstance in the node graph (unless it's used to combine different topics into a single one).
