Ask HN: Robotics projects in consort with the City and build advice

I am looking to build a limited mobility human in loop robot that augments and enhances an existing city function.The robot is on 2–4 wheels and its environment is the city-street(not highway). It need not move too fast (< 4-10 km/h), and its environment is quite observable(via sensors and augmentation). It is under the supervision of a person all the time. Assume location is North America.Here are some questions I don't know the answer to:1. What kind of partnership works best in such cases, VC University-City collaboration? Assume the time horizon is 1-2 years for such a project2. Do accelerators/VCs to mentor one through such a thing exist, and do you know of any?3. What kind of regulations and legal code can kill a project like this(especially if it's like a for-profit startup) and how can I find it quickly within the city bureaucracy?4. Have you built this kind of project or navigated a city bureaucracy to complete a tech project? If so, mind sharing your advice?
