Professor Felix L. Chernousko is Principal Researcher of the Institute for Problems in Mechanics of the Russian Academy of Sciences and graduated from Moscow Institute of Physics and Technology with honor. His research covers various areas of mechanics, control theory, robotics, and applied mathematics. He investigated attitude dynamics of spacecraft subject to external and internal perturbations and analyzed angular motions of bodies containing fluid and elastic parts. His methods and algorithms for optimal control and variational problems were widely used for trajectory optimization of vehicles and robots as well as in solid mechanics. He developed the guaranteed (set-membership) approach to control and estimation based on ellipsoidal bounds for reachable sets. In robotics, he investigated various kinds of mobile robots. He gave plenary talks at many conferences and delivered lectures in a number of universities. He published over 500 papers and 15 books. He is Full Member of the Russian Academy of Sciences, Russian Academy of Engineering, International Academy of Astronautics, European Academy of Sciences, Serbian Academy of Sciences and Arts, and Fellow of the European Mechanics Society. He is Honorary Professor of Moscow Institute of Physics and Technology. He is Member of Editorial Boards of several international scientific journals. He was awarded two Russian State Prizes for Science and Technology, Leninsky Komsomol Prize for Science (the highest Soviet award for scientists under 33), Chaplygin Gold Medal and Andronov Prize of the Russian Academy of Sciences, Koerber Award for the European Science, Alexander von Humboldt Research Prize (Germany), Euler Gold Medal (Euler Foundation), Ishlinsky Prize of Russian National Committee of Theoretical and Applied Mechanics, Gold Medal at the International Trade Fair for Technological Innovation (Brussels), and a medal at the International Robot Olympics (Glasgow, UK). Nikolay N. Bolotnik, Doctor of Sciences (Physics and Mathematics), is Corresponding Member of the Russian Academy of Sciences and Head of the laboratory of robotics and mechatronics at the Ishlinsky Institute for Problems in Mechanics of the Russian Academy of Sciences. His areas of expertise involve mechanics, control theory, optimal shock isolation, and robotics. He is Author of 6 books and more than 200 journal papers on these topics. He is a winner of the State Prize of the Russian Federation for Science and Technology and Andronov Prize of the Russian Academy of Sciences.
