Abstract
Abstract Factors like rising work costs and the imminent transformation and upgrading of manufacturing industries are driving the rapid development of the industrial robotics market. In this study, by analyzing the structure of the transport arm and China Fusion Engineering Test Reactor and performing mathematical modeling, a feasible solution for the robot can be obtained using the dynamic ant colony optimization algorithm and grayscale values. However, for multiple degree of freedom robots, due to a large number of joints, the pure use of joint angle restrictions cannot avoid their own mutual interference. The design of the transport arm robot’s own collision algorithm is shown, which focuses on each linkage as a rod wrapped by a cylinder. The experiment shows that the relationship between the integrated center of mass and the whole machine center of mass can get the action area of the whole machine center of mass of the robot, according to which the relationship between the radius of the catch circle and time of the projection area of the whole machine center of mass of the robot in the horizontal plane can be obtained. The maximum outer circle radius rcom =267.977mm {r}_{\text{com}}=267.977\hspace{.25em}\text{mm} , according to the stability criterion rssa >rcon {r}_{\text{ssa}}\gt {r}_{\text{con}} , can be obtained, so the stability analysis of the gait switching process can be judged to be correct and effective.
工作成本上升、制造业转型升级迫在眉睫等因素推动着工业机器人市场的快速发展。本研究通过对输送臂和中国聚变工程试验堆的结构进行分析,并进行数学建模,利用动态蚁群优化算法和灰度值得到机器人的可行解。然而,对于多自由度机器人来说,由于关节数量众多,单纯利用关节角度限制并不能避免自身的相互干扰。展示了运输臂机器人自身碰撞算法的设计,该算法将每个连杆作为一根被圆柱体包裹的杆。实验表明,综合质心与整机质心的关系可以得到机器人整机质心的作用面积,据此可以得到机器人整机质心在水平面上的投影面积与捕捉圆半径的关系。最大外圆半径r com =267.977 mm {r}_{\text{com}}=267.977\hspace{。25em}\text{mm},根据稳定性判据r ssa >R con {R}_{\text{ssa}}\gt {R}_{\text{con}},从而判断步态切换过程的稳定性分析是正确有效的。
