The intelligent devices have taken us to a convenient and fashionable era, however while we use a pedometer to calculate the number of steps, the blind even do not have the ability to walk independently. There is no doubt that they are eager for convenience and freedom, based on this, this article proposes an intelligent system that assists the blind in walking. The system consists of a crutch and...
The instant development and rapid rise of China's manufacturing industry won the "World Factory" title for China, but in recent years, frequent outbreaks of “quality door” events and global trade frictions made China's manufacturing industry get into crisis. China's manufacturing industry is “big but not strong” and is facing serious development bottleneck in efficiency, benefit, technology,...
To analyse the problem of anisotropy of omni directional robot, kinematic and dynamic equations of Mecanum wheel system are derived according to its structure feature. Considering a typical layout, the influence made by tilted angles of rollers for longitudinal symmetry layout is analysed, rules of omni directional motion can be summarized. Dynamic models with longitudinal symmetry layout are built...
The purpose of this paper was to solve the problems of spectral peak shifting and line splitting existing in Burg's Maximum Entropy Spectral Analysis method (MESA), to enhance the resolution of entropy spectral, and to increase the adaptability of spectral estimation algorithm to signal length, signal noise ratio and initial phase. A method of accelerating Genetic algorithm based maximum Entropy Spectral...
