Refraction AI is a startup in Ann Arbor, Michigan that is building a robotic platform for last-mile delivery. We are disrupting the world of last-mile deliveries in urban areas. Over the last year and a half our team has built a fleet of robots, (called REV-1s), that deliver meals, groceries and other items to residents in the Ann Arbor area. Our platform and software stack address the last-mile delivery problem in a fundamentally different way compared to others in the space. At Refraction, you’ll have the opportunity to work on a unique set of challenges in the autonomy space and implement your solutions on platforms used in the real world.
