METHOD, CONTROL SYSTEM AND MOVEMENT SETTING MEANS FOR CONTROLLING THE MOVEMENTS OF ARTICULATED ARMS OF AN INDUSTRIAL ROBOT
The invention relates to a method for controlling the movements of articulated arms (21, 22, 23) of an industrial robot (2) using a movement setting means (3) to be guided by hand by an operator, the movements of which are provided for generating at least a portion of the movement control data for the industrial robot (2) to be controlled. At least one of a plurality of reference marks (19, 19, 19) is arranged or formed at least on individual articulated arms (21, 22, 23) adjustable by the operator. The movement setting means (3) comprises at least one imaging and/or at least one distance-sensitive sensor (16, 17) which at least one sensor (16, 17) can be set with at least one of the plurality of reference marks (19, 19, 19) into a relative spatial position selected by the operator. During a movement of the movement setting means (3) at least the articulated arm (21, 22, 23) bearing the respectively selected reference mark (19, 19, 19) follows the movements of the movement setting means by control technology. In addition, a corresponding control system (1) and movement setting means (3) are specified.
ROBOTIC POINT CAPTURE AND MOTION CONTROL
This disclosure describes systems, methods, and devices related to robotic point capture and motion control. A robotic device may synchronize one or more robotic device axes with one or more axes of a handheld control device. The robotic device may establish a connection between a robotic device and the handheld control device, wherein the robotic device is capable of moving along the one or more robotic device axes. The robotic device may receive a control signal comprising an indication to transition to a point in space along travel path, wherein the travel path is based on information relating to one or more locations and one or more orientations of the handheld control device. The robotic device may cause to transition an end effector of the robotic device to the point in space based on the indication in the control signal.
ROBOT TRAJECTORY LEARNING BY DEMONSTRATION WITH PROBE SENSOR
A robot learning system for trajectory learning of a robot (RB) having a robot arm between a base and a tool center point (TCP). A user interface allows the user to control the robot arm in order to follow a desired trajectory during a real-time. A probe sensor (PS) is mounted on the TCP during the learning session. The probe sensor (PS) measures a distance parameter (Z) indicative of distance from the TCP and a surface forming the trajectory to be followed, and an orientation parameter (X, Y) indicative of orientation of the TCP and the surface forming the trajectory to be followed. These distance and orientation data are provided as a feedback to the controller of the robot (CTL) during the real-time learning session, thereby allowing the robot controller software to assist the user in following a desired trajectory in a continuous manner. Especially, the probe sensor (PS) may have a displaceable tip (TP) to follow a surface and having a neutral or center position, and where the robot controller software controls the robot movements to seek the neutral or center position irrespective of the user's control inputs. Data (DT) is logged during the learning session, so as to allow later control of the robot (RB) in response to the data (DT) logged during the learning session.

Teach Mode Collision Avoidance System and Method for Industrial Robotic Manipulators
A robot system includes a robot, a teach pendant having an operator interface, and a robot controller with a computer and associated hardware and software containing a virtual representation of the robot and the environment. The system employs a method for avoiding collisions including moving a manipulator arm along an actual path in an environment containing objects constituting collision geometry. Operator input is entered into the teach pendant, whereby the operator is able to directly control motion of the robot along the actual path. A recent history of the motion of the robot is recorded, and a predicted path of the robot is developed based on the input entered into the teach pendant and the recent history of the motion of the robot. Real-time collision checking between the predicted path and the collision geometry is performed while the operator manually controls the robot using the teach pendant.
