<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>
<br>
I have seen on the tutorial of the ROS-Rock bridge some
information about exchange of data, but I don't know if I can
manage this issue from this information, and also how clearly to
do it. <br>
<br>
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>
<br>
Otherwise, what is the list of types that are directly supported
(like USB-camera image)?<br>
<br>
Thank you<br>

<br>
<br>
After configuring the Rock-ROS Bridge, in rock-display, I can see
the Orocos::Ros::NameService. I can see the ROS node (here talker,
see attachment of the node definition, done with rospy). However,
I can not see anything in Output ports (my node is publishing a
Float64). Also, I can not find the topic through ruby scripts.
<br>
<br>
I have alos tried the turtlesim node, without success
(input/output ports are empty in rock-display)
<br>
<br>
I don't know it it is due to a bad configuration of my ROS node or
a problem in rock configuration.
<br>
<br>
Thank you,
<br>
