Iosif S. Paraskevas works in the area of space robotics and mechanisms since 2003. He received his Diploma in Mechanical Engineering (ME) and the M.S. degree from the National Technical University of Athens (NTUA), in 2005 and 2007 respectively. His Diploma Thesis elaborated the use of Percussion Point of robotic manipulators, in order to examine the possibility of its use during capturing of uncontrollable objects, while on the same time reducing the effects of the impact during grasp, to the robot base. This work has been also presented in ESA’s GNC conference in 2005. The master thesis included hardware upgrade of the space emulator of the laboratory, together with some analysis for planar navigation problems. Currently, he is a PhD Candidate in the ME Dept. of NTUA. The work is focused in space robotic systems and on orbit servicing, and the Doctoral Research is being supported by HERAKLEITOS II program since 2010, with funds from Greece and EU. He also participates in the upgrade of the CSL space emulator, of which design and technology has been also presented in various international conferences. He was member of the CSL-NTUA team that was one of the six shortlisted ESA YES3 Mission Proposals and also participates in various research projects of European Space Agency (ESA) since 2008. He is a member of the Technical Chamber of Greece and of the Hellenic Association of Mechanical and Electrical Engineers. He is also an IEEE (Institute of Electrical and Electronic Engineers) Graduate Student Member, ASME (American Society of Mechanical Engineers), AIAA (American Institute of Aeronautics and Astronautics) Student Member and HEL.A.S. (Hellenic Astronomical Society) Junior Member.
