The process of changing the attachment of a demolition robot is a complex operation and requires a high docking accuracy, so it is hard for operators to control this process remotely through the camera's perspective. To solve this problem, this paper studies trajectory planning for changing a demolition robot attachment. This paper establishes a link parameter model of the demolition robot; the position and attitude of the attachment are obtained through a camera, the optimal docking point is calculated to minimize the distance error during angle alignment for attachment change, the inverse kinemics of the demolition robot are solved, the trajectory planning algorithm and visualization program are programmed, and then the trajectory planning for the demolition robot attachment changing method is proposed. The results of calculations and experiments show that the method in this paper can meet the accuracy, efficiency, and safety requirements of demolition robot attachment changing, and it has promising application prospects in the decommissioning and dismantling of nuclear facilities and other radioactive environments.
拆除机器人的附件更换过程是一项复杂的操作,需要很高的对接精度,因此操作人员很难通过摄像头的视角远程控制这一过程。为了解决这个问题,本文研究了拆除机器人附件更换的轨迹规划。本文建立了拆除机器人的连杆参数模型;通过摄像头获取附件的位置和姿态,计算出最优的对接点,以最小化附件更换过程中角度对准的距离误差,求解拆除机器人的逆运动学,编制轨迹规划算法和可视化程序,然后提出了拆除机器人附件更换方法的轨迹规划。计算和实验结果表明,本文方法可以满足拆除机器人附件更换的精度、效率和安全性要求,在核设施退役和其他放射性环境的拆除和拆解方面具有广阔的应用前景。
