Patent number: 11305429Abstract: In the following, a method for synchronizing the motion sequences of at least two robots will be described. In accordance with one embodiment, the method comprises the following: During operation of a robot cell having at least two robots, a path parameter is regularly calculated for each of the at least two robots based on a current position of the respective robot and on a previously specified robot path of the respective robot. The path parameter represents the current position of the robot. Subsequently, a run-ahead limit is calculated for each robot based on the path parameters determined for the respective other robots. Based on the respective calculated run-ahead limit, the path speed of every robot can be adjusted.Type: GrantFiled: September 28, 2016Date of Patent: April 19, 2022Assignees: Atensor Engineering And Technology Systems GmbH, Convergent Information Technologies GmbHInventors: Bernhard Schierz, Wolfgang Stöcher, Gerald Umgeher

Patent number: 9701019Abstract: Workflow charts for processing (e.g., treating, machining) a workpiece with a tool of an industrial robot are automatically generated. An initial chart has a plurality of tool paths for a workpiece in a defined target position and for defined process parameters. The tool path determines the desired movement of the tool along the workpiece. A state space describing variable parameter values that impact the workpiece processing are defined. Each point in the space represents a concrete combination of possible parameter values. The space is discretized into individual states. The processing of the workpiece is simulated using the initial chart for one or several discrete states and the simulated process results are evaluated according to a pre-definable criterion. The initial chart is iteratively modified, subsequently workpiece processing is simulated using the modified chart for at least one discrete state, and the simulated processing results are evaluated with a pre-definable cost function.Type: GrantFiled: September 6, 2012Date of Patent: July 11, 2017Assignee: Convergent Information Technologies GmbHInventors: Christof Eberst, Massimo Ferri, Bernhard Stoeffler, Riccardo Tornese, Gerald Umgeher

Patent number: 8892255Abstract: A method for the automated control of a process robot with a controller performing movement and work sequences and with one or more sensors that record a work progress. A planning tool compares a recorded progress of work with an aimed-for processing objective and determines, from a difference between the processing objective and an actual value of the process that corresponds to the recorded progress of work, movement and work sequences with which the aimed-for processing objective is achieved. Then the determined movement and work sequences are converted into robot-executable control commands in real time or in-step with the process, and the process robot is controlled in such a way as to achieve the aimed-for processing objective.Type: GrantFiled: February 17, 2012Date of Patent: November 18, 2014Assignee: Convergent Information Technologies GmbHInventor: Christof Eberst
