Robotic Painting Systems and Techniques
Summary
Robotic painting systems have evolved from simple pen-plotter designs to sophisticated platforms capable of emulating human artistry and performing industrial surface finishes. Central to these systems are multi-axis manipulators equipped with end-effectors such as brushes, palette knives or sponges, coupled with real-time vision and force sensing. Image-processing pipelines transform source images into stroke or region maps, driving motion planners that generate collision-free trajectories. Increasingly, machine-learning models assist in stroke sequencing and style transfer, while physically motivated brush models ensure accurate reproduction of traditional media. Hybrid force/motion control strategies maintain constant contact pressure on complex geometries, enabling applications from automotive spray painting to adaptive portrait drawing on canvas. Collaborative robots allow safe human–machine interaction and augmented creativity, and mobile platforms extend painting capability to three-dimensional sculptures. Together, these advances underpin a global shift towards automated yet flexible manufacturing, new forms of artistic expression and assistive technologies for users with impairments.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
