The in-pipe cleaning robot (IPCR) is a new equipment for pipelines cleaning. However, most existing in-pipe robots are used to inspection and simple maintenance, etc. They cannot effectively complete the pipelines cleaning works, especially large diameter pipelines. This paper proposes a novel wheeled and wall-pressing type IPCR equipped with new high pressure water jet cleaning device. The whole...
Currently, a large number of clustering algorithms are available for data mining. But it will be difficult for people who to a large extent know little about data mining to select an appropriate clustering algorithm. In order to solve this problem, in this paper, we first comprehensively analyze a number of clustering algorithms, then summarize their evaluation criteria and apply the so-called fuzzy...
The flying mechanism of birds and big insects, especially the rules of wings motion in flight, are investigated. Some details of mechanical frame are also considered. The entire dynamic model of flight attitude for Micro Flapping-wing Aerial Robot(MFAR) is developed. The design of attitude controller is challenging due to the complexity of the flight process, and the heavy difficulties are system...
Phase plane analyzing approach is an intuitive graphical way for the analysis of fuzzy control system, and it can invert the movement of a first and second order system into the track of position and velocity in the phase plane, which is very important to further improve the whole system. However, it can't go without expertise and it is vague in the phase track drawing for stability determination...
