I finally read it. Is is about the IMHuS simulator: https://github.com/LAAS-HRI/IMHuS
It gives a #simulation environment with agents which movement is choreographied, and that can perform actions in the environment.
It is good to #socialnavigation, and #HRI limited to requesting actions to agents in proximity.
It is based on #ROS and #Gazebo, and I suppose #LAAS’ great human-aware planners.
