A method for manipulating a multi-link robotic arm includes: at a first time, recording a first optical image through an optical sensor arranged proximal a distal end of the robotic arm proximal an end effector; detecting a global reference feature in a first position in the first optical image; virtually locating a global reference frame based on the first position of the global reference feature in the first optical image; calculating a first pose of the end effector within the global reference frame at approximately the first time based on the first position of the global reference feature in the first optical image; and driving a set of actuators within the robotic arm to move the end effector from the first pose toward an object keypoint, the object keypoint defined within the global reference frame and representing an estimated location of a target object within range of the end effector.

Detection device and detection method

A detection device and a detection method are provided for robot-induced loads that can act upon the human body in contact with the robot during a working process. The robot-induced loads, in particular forces, are measured by the measuring device (16) of an external sensing device (2). The measuring device (16) is suitably positioned and oriented in this process in the working area of an industrial robot (3) by means of a positioning device (15).

ROBOT CONTROL DEVICE HAVING LEARNING CONTROL FUNCTION
20180117758 · 2018-05-03 ·

A robot control device includes a learning control unit for calculating a learning correction amount, a position storage unit for storing a position of a leading end of a robot mechanism part during the learning control, and a speed storage unit for storing a speed of the leading end of the robot mechanism part during the learning control. The robot control device determines, while the robot mechanism part is operated by a position command after the learning control, whether or not the position and the speed of the leading end are in an abnormal state based on errors with respect to the position and the speed of the leading end stored during the learning control. The robot control device switches a determination as to whether the learning correction amount is applied in accordance with this determination result.

Method For Controlling An Industrial Robot By Touch
20180104817 · 2018-04-19 ·

A robot and method for controlling an industrial robot, which has a first robot arm, a second robot arm, a joint defining a kinematic pair between the first and second robot arms, an actuator for generating relative movement between the first and second robot arms, and a robot controller for controlling the movements of the actuator. The method includes the steps of: determining a presence of a first torque indication at the actuator to be interpreted as a first command to the robot controller; repeatedly obtaining an external torque value (.sub.ext) to obtain an external torque behaviour; comparing the external torque behaviour with the first torque indication; and executing a robot function corresponding to the first command upon detecting that the external torque behaviour corresponds to the first torque indication. The obtained external torque behaviour depends on a reference torque value (.sub.ref) obtained from a dynamic model of the robot
