Design And Invention Of Human Body Imitation Based On MEMS Acceleration Sensors

With the "people first" concept to enhance, people pay more and more attention to their own safety. The thesis mainly focuses on tracking human body movement information, designing and developing a human body imitation device based on MEMS acceleration sensors. Suck kind of device can be used in office environment, for instance, handling the remote operation of robot and other dangerous industrial work. It wins superior performance in reducing the accident casualties.The thesis introduces types of MEMS acceleration sensors, analyses the features. It describes the overall design plan, proposes the system framework, and demonstrates the main functions within the system.On the technology of motion mapping between human limb and"virtual human". Two algorithms are put forward: one is displacement control algorithm points. Due to the lack of precision, an improved method is proposed; The other is the angle position control algorithm. The former one has been the displacement of a relative value, while the axis is changing. The latter one, transforms into the posture angle through three-dimensional space. The author then gives the comparison between the two algorithms in a greater detail.Finally, a prototype system for the human body imitation device is developed by using ADXL330 acceleration sensors made by Analog Devices, based on VC++ and Windows system environment. It is followed by the introduction of the design process of hardware & software.After a thorough comparison with magnetic puppet, we could make the conclusion that the device is portable, low-cost, light and easy-to-install. In addition, the device could detect in a wide range, and function well in direction detection. It has a good promotion prospect in the market.
