    摘要: The invention relates to a method or an apparatus for online calibration and for guiding a multiaxis jointed-arm robot (2) that, with an end effector (4), travels along a preprogrammed path stored in its robot controller (5). The jointed-arm robot (2) moves the end effector (4) along the programmed path during a reference journey with an experimentally performed process and in so doing carries along a test sample from an external guidance system (8). During the robot movement, the position and orientation of the test sample (9) are recorded by an external, in particular optical measuring device and a guidance computer (14) of the guidance system (8). In this case, position, orientation and path errors are detected online and correction values are ascertained and output to the robot controller (5). The robot controller (5) uses the correction values to correct the programmed path as appropriate. The external guidance system (8) and/or the robot controller (5) store the correction values, and in later operation the thus corrected programmed path is travelled along possibly without an external guidance system (8).

    摘要: This invention relates to a visual control robot system for arc welding which can conduct easily and efficiently those operations which are associated with a robot controller and a vision sensor system by an operator through a common operation panel. Before the start of welding, a soft key (9a) disposed on the common operation panel (6) for both the robot controller (5) and vision sensor controller (3) is operated so as to set the robot system to a first mode and under this state, the position of a sample welding member is taught to the robot controller. The soft key is then operated to switch an operation mode to a second mode in order to input parameters for vision teaching of storing a camera image at each point on a reference weld line formed on the sample weld member. The position teaching and the vision teaching can be given via the same operation panel and moreover, the operation common to both can be carried out by the same operation. Correction control is effected during the welding work so that an actual weld line is in agreement with the reference weld line in accordance with the result of comparison between an actual camera image representing a welding state and a camera image at the time of vision teaching corresponding to the former.

    摘要: A robot control method includes a teaching step, first processing step, modifying step, second processing step, and third processing step. In the modifying step, a third teaching point is changed to a second modified point, a fourth teaching point to a third modified point, and a fifth teaching point to a fourth modified point, based on a difference between a second teaching point and a first modified point. A profile modifying control to change the position of a work tool is applied, using a sensor mounted on the processing advancing direction side of the work tool, in the first processing step and the third processing step. An attitude of the work tool is changed during the second processing step.
