Clock topic problem [closed]
Hello all!
I'm using Electric on Ubuntu 10.04, trying the bumper topic in a model, which is loaded in the URDF as everybody knows. The topic is listed (I see it when a type 'rostopic list' with the name '/collision/state/') but when I want to look at the messages ('rostopic echo...') the output is:
WARNING: no messages received and simulated time is active. Is /clock being published?
I have searched for any answer for this problem but I don't find anything. I don't understand why happens this because the /clock topic lists messages, hence it is published. Could anybody help me?
EDIT: I get to solve the problem; I specified an incorrect frameName in the Bumper plugin of gazebo. But there is an aditional problem, the states field in the messages is empty. I put the models intersecting each other but there is no information.
Thanks in advance
