  Marble pioneered early efforts in sidewalk-based autonomous delivery, navigating dense urban micro-environments in real-world trials. Its approach blended robotics, mapped navigation, and human oversight—yielding scalable lessons for subsequent industry players. Though it didn’t scale commercially, Marble helped define the interaction dynamics, safety considerations, and social context of delivery robots.
