Tool Path Planning Method for Industrial Manipulators Based on 3D-Model Obtained From Computer Vision Systems

The paper proposes the method for tool path planning based on the use of a workpiece 3D-model obtained from a computer vision system. The main feature of the proposed method is the automatic separation of elementary paths described by lines or arcs of circles from the initial trajectory passed along the 3D-model surface. This separation is implemented by means of the RANSAC algorithm. The proposed method allows to reduce the number of commands in the generated motion program of the industrial manipulator and increase operations performance since the generated paths will not contain noise from the computer vision system. Preliminary studies performed have shown the efficiency and workability of the proposed method.
