Abstract

A robot-assisted sheet metal bending loading and unloading path planning method based on an SVSDF is provided. The method includes the following steps: Step 1, constructing a two-dimensional pixel coordinate system; Step 2, obtaining an initial motion trajectory of loading and unloading a sheet metal part; Step 3, calculating path safety; Step 4, calculating a path cost; Step 5, calculating a fitness value of the initial motion trajectory of loading and unloading the sheet metal part; Step 6, optimizing the path cost and the path safety to obtain an optimal motion trajectory of loading and unloading the sheet metal part; and Step 7, through derivation of a bending loading and unloading motion relationship, transforming a motion trajectory of loading and unloading a workpiece itself into a motion trajectory of each axis of a bending robot.
