Abstract

This paper describes the development of an intelligent automated control system of a robot manipulator for plasma treatment of medical implants with complex shapes. The two-layer coatings from the Ti wire and hydroxyapatite powders are applied on the surface of Ti medical implants by microplasma spraying to increase the biocompatibility of implants. The coating process requires precise control of a number of parameters, particularly the plasma spray distance and plasma jet traverse velocity. Thus, the development of the robotic plasma surface treatment involves automated path planning. The key idea of the proposed intelligent automatic control system is the use of data of preliminary three-dimensional (3D) scanning of the processed implant by the robot manipulator. The segmentation algorithm of the point cloud from laser scanning of the surface is developed. This methodology is suitable for robotic 3D scanning systems with both non-contact laser distance sensors and video cameras, used in additive manufacturing and medicine.

复杂几何形状医疗产品机器人等离子体加工三维扫描系统的开发

本文介绍了一种用于复杂形状医用植入物等离子体处理的机器人机械手智能自动控制系统的研制。采用微等离子体喷涂技术将钛丝和羟基磷灰石粉末制成的两层涂层涂在钛医用植入物表面，以提高植入物的生物相容性。涂层过程需要精确控制许多参数，特别是等离子体喷射距离和等离子体射流穿越速度。因此，机器人等离子体表面处理的发展涉及到自动路径规划。所提出的智能自动控制系统的核心思想是利用机器人机械手对被加工植入体进行初步三维扫描的数据。提出了激光扫描表面点云的分割算法。该方法适用于具有非接触式激光距离传感器和摄像机的机器人3D扫描系统，用于增材制造和医学。
