2014-08-20 07:03:32 -0500 | commented answer | Cannot load message class for .... Are your messages built? Thank you. I believe that is the way I solved it, but I am not sure what exactly caused the error. For completeness I should also mention, that I figured out why the bumper published only once. It and most other topics only publish something in the case of an event, not constantly with x Hz. |

But if I use rostopic hz or rostopic echo the error form the topic line shows up, eg rosmsg show does also work, eg Now interestingly if I try rostopic echo with "bumper", which is the only std_msg published by the robotino_node it shows one time but that's it. I suspect that my cmake file for the messages is wrong, but I am not sure; it looks like this My launch file looks like this So even if just the std_msgs work, shouldn't at least the bumper published with ...
