Inaccuracies of industrial robot positioning and methods of their correction

Abstract

The application of production lines without the use of robots in heavy, monotonous, unhealthy or high-precision works is not just ineffective and inhumane but also economically unprofitable. The use of robotics in manufacturing processes is therefore necessary to ensure high productivity of products having satisfactory quality and guaranteed repeatability of production. The article points out inaccuracies in positioning the robotic arm tool depending on the robot axes rotation, welding speed and predefined trajectory shape. Fanuc M-710iC/50 robot showed biggest inaccuracies in movement speed of 50 mm/s.
