Aiming at the non-direct measurement disturbances caused by the ground effect on the high-stability control of the aircraft at low altitude, it introduced a design of the height control system based on auto-disturbance rejection control technology in this paper. The use of auto-disturbance-rejection technology can be independent of the precise mathematical model of the aircraft system, which can be...
Nowadays, more and more navigation systems based on the map of the environment have become mature enough to be used in practical application. Because the map is the basis of all these kind of systems, a 2D laser mapping system is designed to overcome some defects of the magnetic guide and RFID parking system used by the substation inspection robot now, and hoped to help the robot to fulfill the navigation...
In this paper, A test bench system used in the test of UAV is put forward. The system is consisted of four parts which includes bearing part of UAV, ground support position, transmission mechanism and measuring weight parts. Bearing part of UAV is used for placing the object to be measured which is connected to one end of the drive mechanism through the connecting shaft, The other end of the drive...
220kV open type substation equipment's surface will readily accumulate industrial and natural filthy when they expose to outdoors in a long-term, and this situation will lead to the phenomenon of flashover. The Substation Water Washing Robot in this paper can transport the high pressure water jet equipment to the operating position by insulated telescopic boom, and then carry out water washing operation...
This paper mainly introduced the research status of hydraulic wrench, the current hydraulic wrench is not suitable for single manual operation, it was mainly used to remove large size bolt, such as above M20. In order to adapt to the demands of the market development, and meet the requirements that one person can conveniently operate on some equipment, the small-sized hydraulic wrench was designed...
In this paper, the high voltage between the insulation design and simulation of mechanical arm was studied, and analysis of the mechanical arm torque, speed and angular acceleration of each joint, etc. Simulation model is established by using solidworks. Simulation model is imported to ansys, the finite element analysis on the composition of the material, mechanical arm calculation to improve the...
