METHOD OF MEASURING ABSOLUTE POSITION OF END LINK OF NDUSTRIAL ROBOT MULTILINK MECHANISM Russian patent published in 2018 - IPC B25J19/00 

FIELD: physics.

SUBSTANCE: in the implementation of the method, two fixed video cameras are used, and the position of the mechanism link is calculated using the equations of inverse kinematics. Herewith outside of the working area of the multilink mechanism of the industrial robot, at least two mutually perpendicular screens are located, and on its end, link the spaced sources of coherent radiation are installed, ensuring that at each tome moment of the light spots at least two sources on the mutually perpendicular screens are visible. The camcorders are located with the ability to view the entire screen area, with their help the position and dynamics of each light spot movement across the screen are fixed, and this data is used to calculate in real time the position of the end link of the industrial robot mechanism.

EFFECT: increasing the accuracy with increasing the working area, increasing the speed due to the high contrast of the light spot on the screen, allowing to select a point object with a minimum amount of calculations.
