Part I: Introduction Are cities ready for self-driving, artificially intelligent, vehicles and robotics? The urban marketplace is increasingly filled with products emblematic of "smart" cities, from widely discussed autonomous vehicles to smaller variations on the theme, such as robotics for delivery, security, and entertainment. 1 Altogether, such urban robotics represent a new wave of technology in which digital sensors, networked devices, and their associated data stores are given the algorithmic, physical, and legal means to move in public space. 2 As time goes on, the public is increasingly likely to encounter self-driving vehicles, robots, and drones on city streets, sidewalks, and in urban airspace. How should cities respond to these new and impending technologies? Firms have technological, market, and financial interest in testing and deploying their products in public space, but the implications for cities span a broad array of intended and unintended consequences. Cities are natural sites of experimentation for firms interested in bringing these products to market, and the perception of economic opportunity associated with tech firms is leading city representatives to reclaim public spaces, transforming them into testbeds for product development. 3 It is worth noting, however, that experimentation involves trial and error, and there are limitations to the ability of artificial intelligence to navigate the wide range of conditions and events that comprise the urban environment. 4 Ultimately, the design of the 1
