The research of hydraulic quadruped bionic robot design

Based on the quadruped robot, this paper mainly studies the two directions of the content. The first part mainly introduces the mechanical structure design and the construction of the control system of the quadruped robot, completes the prototype design of the quadruped robot based on hydraulic power system. The second part studies a few experiments had be made in this thesis such as the marking time experiment, the squat experiment, the walking experiments, the trotting experiments.

The estimation for 2-D direction of arrival based on higher-order cumulant of signals received by circle array

Based on the fourth-order cumulant of signals received by a uniform circular array, a method for estimating the 2D direction of arrival is discussed. It can be employed to estimate parameters in the environment of arbitrary Gaussian noise without any spectral peak searching. The parameter match method is analyzed. An iterative algorithm for the higher-order cumulant is discussed, with which the process of data sampling and parameter estimating can be done in parallel. The validity of the method is proved by the results of simulation.

Electric control and design for automatic precision forging production line

This paper presents a precision forging line of plate spares production. The line include press, robot, heating furnace, convey. Main computer control each device work in coordination with each other. Robots are used to carry spares automatically. The line is automatic control and high efficient, high quality.
