Simulation of robotic painting for electrostatic wraparound applications

A system to simulate electrostatic painting on a real-world object, the system comprising:

• a processor;
• and
• a memory with computer code instructions stored thereon, the processor and the memory, with the computer code instructions being configured to cause the system to:
• receive an indication of paint deposition rate and an indication of maximum paint accumulation for a given real-world robotically controlled electrostatic paint gun, wherein the indication of maximum paint accumulation is indicative of maximum wrap-around paint accumulation for the given real-world robotically controlled electrostatic paint gun;
• represent paint deposition of the given real-world robotically controlled electrostatic paint gun in a virtual environment, said representing, for a subject time period, computing total paint accumulation on a given surface element of a model representing the real-world object, computing total paint accumulation including:
• if there is a wrap-around path within a spray zone of the paint gun for paint particles to reach the given surface element, determining wrap-around paint accumulation on the given surface element during the subject time period using the indication of paint deposition rate, where the wrap-around paint accumulation during the subject time period stops if the maximum paint accumulation is reached;
• determining direct paint accumulation on the given surface element for the subject time period;
• and
• determining total paint accumulation for the given surface element for the subject time period by summing the determined wrap-around paint accumulation and the determined direct paint accumulation;
• and
• generate a parameter file including parameters accounting for the determined total paint accumulation for the given surface element, the generated parameter file enabling precision operation of the given real-world robotically controlled electrostatic paint gun to paint the real-world object.
