摘要
对双臂作业机器人的协调控制问题进行分析,采用D-H法在直角坐标系下建立了机器人双臂联合运动学模型。通过在机械臂的每个连杆机构上建立坐标系,得到主机械臂的D-H参数,解出主机械臂运动学正解。在已知约束条件下,通过在末端执行器上添加点驱动,规划单臂运动路径。借助ADAMS软件运动仿真,在后处理模块中得到主机械臂各个关节角度随时间变化的曲线图,曲线过渡平滑,角度变化在预先设定的转角范围内,满足操作任务要求。
The method of D-H is adopted by establishing the united kinematics model of the arms of robot in the Cartesian coordinate system after analyzing the question of coordinate control for dual-arm operation robot. Through establishing coordinate system in each link mechanism of robot, the D-H parameters of master manipulator are acquired, which are applied for the correct answer of kinematics of master manipulator. In some known constraints, planning motion path of master manipulator by adding point motion on the end effectors. The curves in figure of Joint angle change with time can be acquired in post-processing module after motion simulation by ADAMS. The figure indicates the curves transit smoothly and the angles change in range of angles which are set, that can meet the requests of operational text.
