一种可变径多模式移动并联机器人的设计与分析
Design and analysis of a variable-diameter multi-mode mobile parallel robot
摘要
Abstract
Aiming at the problem of insufficient folding and unfolding ability and multi-mode adaptability of mobile robots in complex unstructured environments,a variable-diameter multi-mode mobile parallel robot composed of a variable-diameter platform and a 4-URU parallel mechanism is proposed.Firstly,a variable-diameter platform with multiple radial telescopic rods was designed based on the cam mechanism characteristics,and its structure and force characteristics were analyzed.Then,combining the telescopic characteristics of the variable-diameter platform,a multi-mode mobile parallel robot was constructed with the 4-URU parallel mechanism as the main body.The degrees of freedom of the 4-URU parallel mechanism were analyzed by spiral theory,and the degrees of freedom and switching methods under different motion modes were obtained.On this basis,the ZMP(zero moment point)theory was used to evaluate the stability of the robot in various modes.Finally,the obstacle-crossing performance and stability of the robot in narrow-slit crossing,single-loop rolling and dual-wheel obstacle crossing modes were verified through ADAMS simulation and prototype experiments.The results show that the designed mobile parallel robot has good folding and unfolding ability and multi-mode adaptability,which can provide a new solution for the design and application of multi-functional mobile robots in complex environments.关键词
