It's teaming up with Cartken, a California-based company that creates self-driving sidewalk robots, to roll out the new delivery program in the Dadeland area.While this is Cartken's first major partnership, the company's fleet of AI-powered robots have been deployed in a number of other places, including parts of California, Canada, the United Kingdom, Germany, Japan and a handful of US college campuses.The six-wheeled robots can take about two dozen pounds of deliveries on the go and has cameras that help guide it to its destination.Uber and Cartken will start working with select merchants today to get the robot delivery system going, with plans to expand to other parts of Miami-Dade and additional cities in 2023."Miami is a thriving Uber Eats market and we are excited to bring its residents a little more Uber magic through sidewalk robot delivery," said Noah Zych, Global Head of Autonomous Mobility and Delivery at Uber, in a press release."
