When controlling a robot remotely, the actual situation on site is often poorly assessed, leading to an increase in incorrect decisions. The control system of robots must be designed wisely to ensure proper human-robot interaction.The experiment MEROP of the University of Lisbon, Portugal aims to improve the remote control of rovers by providing the control system with a toolbox for problem solving. This should prevent unexpected autonomous actions by robots and guarantee secure communication. To achieve this, the analog astronauts will be able to switch between semi-autonomous control and direct control of the robots. Semi-autonomous control allows indirect control with a virtual avatar. The advantage of direct control is an improved situational awareness.
