Hi Guys,

I am currently on a mission to recreate 3d navigation functionality described in the paper "Real-Time Navigation in 3D Environments Based on Depth Camera Data" by Armin Hornung et. el.

I have gone through the process of installing and validating the ROS install (Hydro), and am now trying to just get the following command to work:

roslaunch nao_bringup nao_sim.launch

When I launch the command I get the following error:

I have validated that the required packages are installed using rosdeps and roscd.

I am on ubuntu precise64, ROS hydro and pynaoqi-python-2.7-naoqi-1.14-linux64.

Any help would be appreciated!

What happens if you just start a single node, e.g. "rosrun nao_driver"? (start a roscore in a separate terminal before, as well as NaoQI)

I have only tried for 30 minutes, but at this stage that command simply exits without any real output, besides: No handlers could be found for logger "rosout" I have checked the logs, they are also empty. I will continue some more tomorrow.

have you sourced your workspace? Like the command below source /devel/setup.bash

yes, I have sourced ./devel/setup.bash

Hi! I have the same poblems, No handlers could be found for logger rosout. My configuration system is similar (ubuntu 12.04 64, ROS hydro and pynaoqi 1.14.5) for the Installation of ROS for NAO I followed the Armin's tutorials "ROS on a remote PC" but I installed just the precompiled binaries. should I uninstall them and install the github ones? including the extras_nao? Quinton Anderson, did you solve the problem? thank you!

Hi, I didn't get it working, but I haven't tried very hard yet. I have been distracted at work. I will get back to focussing on it shortly.

Quinton, our problem is the linking with the pynaoqi (export PYTHONPATH="$PYTHONPATH:$HOME/path/to/pynaoqi/") in my case i have an error in the path to pynaoqi. now I have other problem when i launch the NAOnodes (ERROR: cannot launch node of type [nao_driver/nao_sensors_cpp]: can't locate node [nao_sensors_cpp] in package [nao_driver]) .

@PabloM That is a different problem, you try to launch the C++ nodes. They require that you compile them for the robot (with the C++ SDK). You should try launching the Python nodes instead.
