Teleoperation's overall goal is to give the operator situational awareness (i.e., a sense of being there) of the remote environment and the ability to interact conveniently
This PhD aims to explore the opportunities to improve teleoperation using adaptive robotic assistance and improved information interfaces by considering mental workload (MWL) demands. It will include studies on robotic assistance levels and interfaces that dynamically respond to the operator's MWL for teleoperation. The following objectives will be met to achieve this aim:
Several pieces of literature have demonstrated how haptic guidance based on the sense of touch can be deployed for robotic assistance. For example, haptic shared control and haptic traded control, which the operators and the system share and take turns in the control task, respectively. This work will explore how these assistance schemes could potentially be used with low-level autonomy degrees alongside improved information interfaces that respond to an operator's physical and cognitive demands within structured environments for repetitive and predictable tasks. It will combine some physiological, subjective and performance measures to give an improved assessment and evaluation of the operator's mental workload to understand its relationships with teleoperation tasks. With these improved systems, operators can perform their work more conveniently, faster, and accurately, increasing operational safety and reducing operational costs.
