The main objective of the report is to develop a new non-traditional (propeller free) mobile floating and diving robot. It is intended to investigate new elastomeric materials (e.g., silicone, rubber) properties and to perform structural studies with the intention of using them in underwater robot body, fin and tail constructions synthesis. The robot motion control system is analyzed, adaptive management principles are used. New approaches to gain energy and recharge power pack sources from surrounding medium are investigated in order to create a robot which will be able to operate autonomously. The importance of the proposed system is in further advancement of science of robotics and development of new drives. In particular, potential impact on the report can be characterized by application of innovative materials and technology research, implementation of renewable energy and as a result development of a new robot with unconventional drive and energy restoration possibility. For theory validation the wind tunnel is used. Possibility of energy extraction by vibration motions in water flow is checked experimentally.
