<div class="moz-cite-prefix">After having an issue regarding the
reception of Plain Float64 value from ROS, there were a fix done
by Sylvain for it. Today we tested another communication from
our robot, with another type (here UInt32MultiArray (array of 6
int), also from the sdt_msgs.msgs ) and the same issue happens,
being that rock-display doesn't show the topics bellow the node
name. Beside to that, we could see in the rock display the topic
sent by the USB-camera of the robot, that works very well.<br>

This message is not mapped to Rock types, so not displayed.<br>

I'll try to clarify the documentation and see if you can manage,
then

I would indeed prefer to be able to add the needed code myself,
as I don't know today the kind of information exchange I want to
perform in the future. <br>

Don't worry, we don't want to have to add ourselves all the types
that people would like to exchange between ROS and Rock.<br>

Currently, the only complex ROS message mapped to Rock is the image.
See the ros_mappings statement at the end of
base/orogen/types/base.orogen.<br>
