This standalone video presents a brief history of robot painting projects with the intention of educating viewers about the specific, core robotics challenges that people developing robot painters face. We focus on four robotics challenges: controls, the simulation-to-reality gap, generative intelligence, and human-robot interaction. We show how various projects tackle these challenges with quotes from experts in the field. Video clips from projects, such as Harold Cohen's AARON robot in 1968, to Ken Goldberg's robot art in 1990, through the FRIDA robot's contemporary artwork, and many more, walk viewers through the history of robot painting while highlighting contributions made in the field of robotics. We demonstrate through entertaining videos that robot painting is not a toy domain, it touches upon all core robotics challenges, making it not only one of the more enjoyable spaces to work, given its aesthetic nature, but fruitful in terms of possibilities to make great contributions to general robotics and artificial intelligence research.Authors: Peter Schaldenbrand, Gerry Chen, Vihaan Misra, Lorie Chen, Ken Goldberg, and Jean OhInstitution: CMU
