Abstract: Recently, one can observe increasing number of small devices or sensors in many applicationsthat have to be powered by an energy which can be extracted from surroundings. Simple energyharvesting concept from mechanical vibrations of magnetostrictive materials is based on linear beamwith external excitation. In this case, the beam under load vibrates, and experiences stress or strain.This changes the beam shape which causes direction of sample magnetization (Villari effect) thatcan be captured by external coil and transferred to electrical power. In general, the higher amplitudeof beam vibrations, the higher energy can be extracted from the system. This can be achieve in thevicinity of a resonant frequency. In this paper, we propose energy harvesting model based on linearmagnetostrictive (MsM) beam with external coil. We analyse different shapes of the beam withrespect to different resonant frequencies.

Abstract: This paper describes general approach for creation the effective kinetic energy recovery system in mobile machines using flywheels. It’s should be a mechatronic system. The system with accelerometer-gyroscope and proportional, integral and differential controller (PID-regulator) is proposed as example of automatic control.

Abstract: The mankind is on a threshold of the next industrial revolution which will entail distribution and use of more and more flexible, reasonable, sensitive and effective robots at factory, in establishment and in all other areas of our daily life. This fact in a combination to sharper comprehension of safety issues of the person promoted occurrence of need for a lot of handling robots.
