This repository contains the C++ implementation of active inference for robot control. For simulation purposes, this repo can be handy instead https://github.com/cpezzato/panda_simulation

This package was developed to support the theoretical results of this work:

This repository contains the implementation of active infernce to control the real Franka Emika Panda 7-DOF robot arm. The control is going to be in joint space using torque commands and position/velocity sensors. This can be done either using libfranca (https://frankaemika.github.io/docs/installation_linux.html) using the scripts AICpanda.ccp and AICpickandplace.cpp. Or, through ros infrastructure using the package franka_custom_controllers, to be installed within the official franka_ros https://frankaemika.github.io/docs/franka_ros.html.

"AICpanda.cpp" makes the robot move to a desired goal. "AICpandapickplace" makes the robot perform a cycle which to mimic the pick and place of objects.

The repository also contains a ROS package to use the ROS infrasctucture to control the Panda. The package should be installed within franka_ros. Just clone the package in your franka_ros installation.
