Dimitrios Papageorgiou

Post-Doctoral researcher - Department of Electrical & Computer Engineering, AUTh

Dr. Dimitrios Papageorgiou got his Diploma in Electrical and Computer Engineering in 2013 and his Ph.D. in 2019 from the Department of Electrical and Computer Engineering of the Aristotle University of Thessaloniki. His doctoral dissertation concerned the control of collaborative robots using dynamic systems and restrictions, while his research interests include mainly natural human-robot interaction and real-time motion generation using dynamic systems. His teaching experience includes the teaching of the courses "Automated Control Systems I" and "Robotics" at the Department of Electrical and Computer Engineering of the Aristotle University of Thessaloniki. He is co-author of 15 papers in international scientific journals and conferences and has taken part in 3 European and national research projects related to human-robot collaboration.

Controlling robots that work with humans

For more than three decades, robots are an integral part of world industrial production. Until today, industrial robots are placed in a limited and fully structured work environment, and they are programmed in order to perform one specific job, e.g. take and place an object. Any other work requires reprogramming. Industrial needs have led to the use of high-powered robots capable of handling large loads and / or operating at relatively high speeds, primarily to optimize production time, which makes their operation close to humans dangerous. Therefore, for safety reasons, the robot environment is, to date, a prohibited area for humans, with the use of fences and / or safety signs to be the means of deterring human presence in this area. In recent years, due to robotics, robots are being pushed out of the industrial environment by extending their use to social environments where human interaction is both natural and social. Some examples of such uses are: robot operation in a home environment, elder care, human assistance in the surgery, and finding / rescuing survivors. At the same time, the development of the industry requires the dismantling of the barrier between man and robot, as cooperation between them is expected to bring improved performance and production flexibility. Due to the above, recently a new generation of robots has created, called "Collaborative Robots or Cobots", which are able to co-exist and work with humans, adapt to possible changes in the environment, as well as to learn from man. In this speech, solutions will be presented for a subset of the problems involved in collaborative robot control. In particular, the speech will focus both on the imposition of virtual security and human assistance constraints in working with the robot, as well as on the problem of teaching a kinematic behavior to the robot.
