Using Nao's Camera

Firstly follow the Nao tutorial to set up the Nao Components.

Then to launch the camera node you can run

rosrun nao_driver nao_camera.py

or add

<node pkg="nao_driver" type="nao_camera.py" name="nao_camera" required="true" args="--pip=$(env NAO_IP) --pport=$(env NAO_PORT)" output="screen"/>

to your launch file

Now once that is running you should be able to run

rostopic echo /image_raw

And see lots of numbers filling your screen fast.

From here follow this tutorial to learn about how to use this image data.
