A method for the control of a robot assembly having at least one robot. The method includes acquiring pose data from an object arrangement having at least one object, which data has a first time interval; determining modified pose data from the object arrangement, which data has a second time interval that is larger or smaller than the first time interval, or is equal to the first time interval, on the basis of the acquired pose data; and controlling the robot assembly on the basis of said modified pose data.

Control of a robot assembly

A method for controlling a manipulator includes releasing the manipulator in reaction to a release request by an operator, wherein the recognition of the release request involves monitoring the variation over time of a measured value that is characteristic of a state of the manipulator. Increased robustness of the recognition of the release request results.

In one aspect, a method for controlling a compliant-controlled robot includes performing a boundary monitoring of the robot and controlling movement of the robot with a return force that is predetermined by control technology. If the robot is already in a blocked area upon activation of the boundary monitoring, then a first return force operates to return the robot from a current position in the blocked area toward a boundary of the blocked area. If the robot arrived at the current position in the blocked area after activation of the boundary monitoring, then a second return force operates to return the robot from the current position toward the boundary. The first return force is at least temporarily less than the second return force.

Controlling a compliant-controlled robot

A method for switching a control of a robot into a manual operating mode, wherein the robot is movable by a user manually applying at least one of a force or a torque upon the robot, includes detecting at least one of joint forces or joint torques of the robot, and triggering an error reaction in response to the switching and based on at least one of the detected joint forces and/or joint torques, target joint forces and/or target joint torques, or a pose of the robot.

A method for controlling a robot having a drive arrangement with at least one drive includes determining an actual velocity of the robot, determining a target velocity for the robot, and determining a damping drive parameter based on a difference between the target velocity and the actual velocity. The target velocity is determined based on at least one of a predetermined maximum velocity, a predetermined minimum velocity, or a first distance of the robot from at least one predetermined boundary. The drive arrangement of the robot is then controlled based on the damping drive parameter.

A method for controlling a manipulator includes determining by a control device one or more contact force values between the manipulator and a first workpiece. Each of the contact force values is based on an actual driving force of the manipulator and a drive force according to a dynamic model of the manipulator. The method also includes at least one of a) measuring in multiple stages an orientation and location of the first workpiece based on at least one of the one or more determined contact force values or b) joining a second workpiece and the first workpiece under a compliant regulation, where a joining state of the first and second workpieces is monitored based on at least one of an end pose of the manipulator obtained under the compliant regulation, a speed of a temporal change of the manipulator, or at least one of the one or more determined contact force values.

Method and device for controlling a manipulator

An apparatus for recording positions in a control program of a manipulator, which includes a manipulator, a controller having a control program, and a manual control device, wherein the controller can actuate the manipulatorin a compliance control, in which the manipulator is allowed to occupy an actual position different to the nominal position, wherein the controller, when recording the current position of the manipulator in the control program, carries over into the control program in a situation-based manner the nominal position, the actual position or a hybrid position comprising nominal and actual components of the current position. In addition, a corresponding method is also disclosed.

Apparatus and method for recording positions

In a method and a device for entering control commands into a controller of a manipulator, such as a robot, a first force or movement or sequence of forces or movements is detected, and the detected force, movement or sequence is electronically compared with stored forces, movements or sequences, respectively. Each of the stored forces or movements or sequences has a control command associated therewith. Upon the comparison indicating a coincidence between the detected force or movement or sequence with one of the stored forces or movements or sequences, the control command associated with that one of the stored forces, stored movements or stored sequences is automatically supplied as an input to the controller for operating the manipulator.

The invention relates to a method for mounting a component, which comprises an insertion part and a holding part, in an opening in a workpiece by means of an industrial robot, which has an end effector, which guides the component on the holding part thereof. The method according to the invention is implemented by causing the insertion part of the component to approach the opening by moving the industrial robot; increasing the process forces by means of the industrial robot, once the insertion part of the component has made contact with the workpiece, until a process force threshold is reached, wherein the process forces are stored particularly in the form of material stresses; increasing the flexibility of the industrial robot when the process force threshold is reached; and executing a passive centering movement of the industrial robot based upon the process forces that are released by a relaxation of the material.
