Preprint: Cristian Meo and Pablo Lanillos (2021). "Multimodal VAE Active Inference Controller". https://arxiv.org/abs/2103.04412#

This repository includes the code for the MAIF torque controller code and the tests with the 7DOF Panda robot.

• ROS (melodic)
• pytorch 1.7.0
• cv2
• seaborn 0.11.0

Once the dependencies are installed, a catkin workspace has to be created. To do it:

• Create a folder for your catkin_ws: $ mkdir -p your_catkin_ws/src
• Move to the folder: $ cd your_catkin_ws/src
• Clone the repository $ git clone https://github.com/Cmeo97/MAIF
• Move back to your_catkin_ws: $ cd ..
• Build the workspace: $ catkin_make
• Source: $ source devel/setup.bash

To run the controller:

• After building and sorcing the workspace you have to launch the simulation: $ roslaunch panda_simulation simulation_py.launch The launch file launches a Gazebo simulation in pause, start the simulation pressing Gazebo play button.

• Go to the controller folder: $ cd src/panda_simulation/panda_control_MAIF/src

• You have to run the camera node, which subscribe images from Gazebo and publish them for the controller: $ python2.7 camera.py

• then, in another terminal, run the controller: $ python MAIF_controller.py

• To run the Mental simulation, go to the controller folder: $ cd src/panda_simulation/panda_control_MAIF/src

• and run: $ python Brain_Simulation.py
