The recent developments in the collaborative application of robotic systems introduce a close Human-Machine Interaction (HMI). Most efforts focus on defining safe scenarios during solution designs and standardization of processes, while cognitive and psychological aspects remain important factors to be further developed. New technologies increase productivity and flexibility, but new or higher risks can arise if not well managed. Industry 5.0 places the wellbeing of the worker at the centre of the production process.

The new regulation on machinery products requires that manufacturing companies avoid all risks related to moving parts and psychological stress at the same time. In particular, it requires that machinery products with a certain level of autonomy, and fully or partially evolving behavior or logic, should be adapted to respond to people adequately and appropriately.

This means the interaction system shoud be designed to get proportionate to the required input and to the reaction or behaviour that has to be determined (for ex. requiring the attention, improving the situation awareness, maintaining a right level of stress), suitable for the intended context, scenario and task. In this study, we analyse the issues for operator's safety and health in a robot system application and the opportunities to design adaptive systems.

This paper highlights those characteristics miss in technical standardization in order to be compliant with the new requirements of new Machine Regulation to maintain the right Mental Work Load (MWL).
