where can I find the parameter in Hydro instead of "velocity" in groovy ??
when i use hydro to work through TF tutorial. it says There is no attribute "Velocity" in the module.(listener part) and I tried to change it to cmd_vel but it still does not work...... where can I find the parameter in Hydro instead of "velocity" in groovy ?? There may be other parameter changed in Hydro, how can I get them??
the tutorial's link: http://wiki.ros.org/tf/Tutorials/Writing%20a%20tf%20listener%20%28Python%29 the problem is about line 19 of "nodes/turtle_tf_listener.py"
those tutorials are a bit outdated. You could file an issue: https://github.com/ros/geometry/issues?state=open
