This project has developed a unique robotic spraying gun with an array of sensors to capture the trajectory motions of manual operators and their spraying parameters. These data are recorded in a database, and a specially developed software programme allows operators to review and modify the spraying profile in the database. This in turn permits pattern variation, which provides a ‘handmade’ effect. A six-axis manipulator has been developed to perform the spraying action automatically by making use of the data and analysis.
