Successful disputation of Dr. Mehrach Saki!
We congratulate Mehrach Saki, who completed his doctorate at the Department of Work and Organizational Psychology under Prof. Oliver Sträter.
In his dissertation entitled"Influence of the trajectory in human-robot collaboration - comparison of point-to-point and individualized trajectories with regard to distance behaviour, trust and efficiency", he investigated the influence of anthropomorphic characteristics - such as human joint angles, natural speeds and predictable movements - on trust in collaborative robots.
The focus is on an individually programmed trajectory ("individual trajectory"), which is created by mirroring human arm movements. To this end, Mr. Saki designed, manufactured and programmed an articulated-arm robot that uses motion capturing to program the robot's trajectory using its own arm movement.
The results show: The individual trajectory with its anthropomorphic characteristics led to a significantly higher confidence of the test subjects in the MRK system compared to the classic point-to-point movement. The number of visual fixations on the robot was also lower - an indication of an increased feeling of safety during the collaboration.
These findings provide important impulses for the development of human-centered and intuitive robot systems in industry.
Congratulations on this great success and all the best for the future!
