Konstantinos E. Machairas was born in Athens in April 1989. He received his Diploma in Mechanical Engineering from the National Technical University of Athens (NTUA) in February 2013. His Diploma thesis concerned the design and the implementation of the electrical/ electronic subsystem, and the real-time programming for a space emulator robot. This work was also presented in ESA’s ASTRA conference in 2013. Since April 2013, he is a PhD Candidate in the Department of Mechanical Engineering of NTUA. His current research focuses on dynamics and control of legged robots. He works in the area of embedded systems and robotics since 2010, and he has received several awards and distinctions for his work. He has also worked as an intern in Mechanical Engineering Dept.  in TU Clausthal in Germany, on the spline shaft-hub connections analysis in Ansys Mechanical APDL.
