Autonomous exploration, active learning and human guidance with open-source Poppy humanoid robot platform and Explauto library. The folder ros contains a ROS package to be symlinked to your ROS workspace.

• Install ROS Comm http://wiki.ros.org/ROSberryPi/Installing%20ROS%20Indigo%20on%20Raspberry%20Pi
• Compile with catkin_make_isolated -DPYTHON_EXECUTABLE=/home/poppy/miniconda/
• clone https://github.com/ros/common_msgs.git
• Set export LC_ALL=C in bashrc to prevent terminate called after throwing an instance of 'std::runtime_error' what(): locale::facet::_S_create_c_locale name not valid errors
• Add the NIPS package to ros_ws/src now
• catkin_make_isolated --pkg nips2016
• sudo apt-get install swig scons
• pip install RPi.GPIO
• cd ~/Repos && git clone https://github.com/ymollard/rpi_ws281x.git
• scons && cd python && sudo python setup.py install (install in system dir, not in miniconda, as root will run this code)
• Replace the home page for the Poppy monitor, the ROS node will serve its server

sudo apt-get install python-pyaudio
sudo pip install flask flask-cors
ln -s ~/NIPS2016/ros/workstation.sh ~/catkin_ws/fuzz.sh

# Login as root as a fix to be able to connect to the LED strip (RPi's PWM pin)
ssh root@fuzz.local -X
cd /home/poppy/ros_ws/
./fuzz.sh
roslaunch nips2016 raspberry_pi.launch

cd ~/catkin_ws/fuzz.sh
./fuzz.sh

The BASH script hereabove setups ROS vairable to use fuzz.local as the ROS master. Then choose to start either the services/publishers OR the full experiment (services/publishers + controller) on your workstation:

roslaunch nips2016 workstation.launch

You are then able to monitor topics and call services of all nodes running on the workstation:

roslaunch nips2016 start.launch

You can also pass the following arguments:

• source:=string that will be used as a source experiment in case of time travel
• name:=<string> that will be used to output log files (a pickle file in logs/). Be careful that this name is prefixed by the timestamp before using it as a source file
• iterations:=<integer> that will automatically stop the controller after a certain number of iteration (aka trials). If you're using a source file then iterations must be greater than the number of iterations recorded in the source file.

For example:

roslaunch nips2016 start.launch name:=new_experiment old:=2016-11-29_14-48-12_old_experiment iterations:=6000

roscd nips2016/logs

This command will bring you to the folder containing recored experiments, if any.
