    • A method for controlling a painting system including an industrial robot or manipulator arm arranged with a wrist section and carrying a paint applicator arranged on the robot wrist is described. Paint is applied by the applicator to a substantially circular or elliptical area on the surface, the center of the area being defined as a Tool Center Point. The wrist section is arranged capable of moving and orienting the paint applicator. In the method, the paint applicator is moved by the manipulator arm so that the Tool Center Point moves along a planned path so coating a part of the surface. The planned path may include one or more bends. The path taken by the robot wrist may be controlled to follow a different path from the path taken by the Tool Center Point. A system and a computer program for carrying out the method are also described.
    • 描述了一种用于控制涂漆系统的方法,其包括布置有手腕部分并且携带布置在机器人手腕上的涂料涂抹器的工业机器人或操纵臂。 油漆通过施加器施加到表面上的大致圆形或椭圆形区域,该区域的中心被定义为工具中心点。 手腕部分布置成能够移动和定向涂料器。 在该方法中,涂抹器由操纵臂移动,使得刀具中心点沿着规划路径移动,从而涂覆表面的一部分。 计划的路径可以包括一个或多个弯曲。 可以控制机器人手腕所采取的路径,以跟随与刀具中心点所采取的路径不同的路径。 还描述了用于执行该方法的系统和计算机程序。

    • Disclosed is a method and system for finding a relationship between a tool-frame of a tool attached at a wrist of a robot and robot kinematics of the robot using an external camera. The position and orientation of the wrist of the robot define a wrist-frame for the robot that is known. The relationship of the tool-frame and/or the Tool Center Point (TCP) of the tool is initially unknown. For an embodiment, the camera captures an image of the tool. An appropriate point on the image is designated as the TCP of the tool. The robot is moved such that the wrist is placed into a plurality of poses. Each pose of the plurality of poses is constrained such that the TCP point on the image falls within a specified geometric constraint (e.g. a point or a line). A TCP of the tool relative to the wrist frame of the robot is calculated as a function of the specified geometric constraint and as a function of the position and orientation of the wrist for each pose of the plurality of poses. An embodiment may define the tool-frame relative to the wrist frame as the calculated TCP relative to the wrist frame. Other embodiments may further refine the calibration of the tool-frame to account for tool orientation and possibly for a tool operation direction. An embodiment may calibrate the camera using a simplified extrinsic technique that obtains the extrinsic parameters of the calibration, but not other calibration parameters.
    • 公开了一种用于找到机器人手腕附近的工具的工具框与使用外部照相机的机器人的机器人运动学之间的关系的方法和系统。 机器人手腕的位置和方位定义了已知的机器人的腕架。 工具框和/或工具的工具中心点(TCP)之间的关系最初是未知的。 对于一个实施例,相机捕获该工具的图像。 图像上的一个适当点被指定为工具的TCP。 移动机器人使得手腕被放置成多个姿势。 多个姿势中的每个姿势受到限制,使得图像上的TCP点落在指定的几何约束(例如点或线)内。 根据指定的几何约束计算工具相对于机器人的腕架的TCP,并且作为多个姿态的每个姿态的手腕的位置和方向的函数来计算。 实施例可以相对于腕架来定义相对于腕架的工具框架,作为相对于腕架的计算的TCP。 其他实施例可以进一步细化工具框架的校准,以解决刀具取向并且可能地用于刀具操作方向。 实施例可以使用获得校准的外在参数而不是其它校准参数的简化外在技术校准摄像机。
