Those are some very interesting ideas! I'd love to see this for city planning. Maybe China lol. The "Urban planning in communist states" had similar benefits but our current technology e.g. just smartphone apps could also help or optimize or solve a lot of these issues for free.
But I don't think these robots actually need to be expensive. I believe a local model on a smartphone could basically do this already and then you just have an RC car with a different gearing and a box. Like if a country had state owned facilities with regular open optimization challenges this would cost basically nothing.
A lot of things should be rethought. And thanks to climate change and migration we will have to build a lot of cities.
