Abstract: A method for performing coordinated stationary tracking during a welding operation performed on a cylindrical part includes mounting a cylindrical part on a rotating arm having a central rotational axis and directing a welding torch to a weld position wherein the welding torch is directed toward an initial weld joint position. The rotating arm is rotated about the central rotational axis thereof to provide relative movement between the cylindrical part and the welding torch when the welding torch is positioned at the weld position. During the rotating of the rotating arm the welding torch remains substantially stationary while a tracking sensor of the welding robot periodically determines geometric information of the cylindrical part based on a rotational position of the rotating arm. The geometric information regarding the cylindrical part is then used to determine vertical and lateral offsets to be applied to the welding torch relative to the weld position.

Abstract: A method for adaptive control of a robotic operation of a robot includes providing a software program to generate process signals executable during the robotic operation, including one or more execution commands. A first Signal Value channel is provided to control at least one control process parameter of the robot, where the first Signal Value channel is subject to a first time latency. The execution timing of the first Signal Value channel is synchronized with the one or more execution commands by accounting for the first time latency in relation to the one or more execution commands. The software program is run to generate the process signals and the robot is operated in response to the synchronized execution timing of the execution commands.
