I am trying to get a graph of what is running on my turtlebot but when I start rxgraph after the turtlebot_bringup.launch it stops and says there is an index out of range error. Here is the output from the terminal where I ran rxgraph:
Traceback (most recent call last):
File "/opt/ros/diamondback/stacks/rx/rxgraph/src/rxgraph/impl.py", line 123, in run
changed = g.update()
File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/graph.py", line 568, in update
updated = self._node_refresh(next) or updated
File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/graph.py", line 452, in _node_refresh
updated = self._node_refresh_businfo(node, api, bad_node)
File "/opt/ros/diamondback/stacks/ros_comm/tools/rosgraph/src/rosgraph/impl/graph.py", line 407, in _node_refresh_businfo
connection_id = info[0]
IndexError: list index out of range
As a final note, rxgraph runs fine with other applications but with the turtlebot_bringup.launch it produces the above.
Any ideas?
This is a known bug in rxgraph ticketed here: https://code.ros.org/trac/ros/ticket/3579
you can use rosnode list to see the list of node running on your TurtleBot
