  The fast urbanization and climate change challenges require solutions that
enable the efficient movement of people and goods in cities. We envision future
cities to be composed of high-performing walkable districts where
transportation needs could be served by fleets of ultra-lightweight shared and
autonomous vehicles. A future in which most vehicles would be autonomous
creates a new paradigm for the possible interactions between vehicles. Natural
swarms are a great example of how rich interactions can be; they can divide
tasks, cluster, build together, or transport cooperatively. The field of swarm
robotics has translated some of the behaviors from natural swarms to artificial
systems, proving to make systems more flexible, scalable, and robust. Inspired
by nature and supported by swarm robotics, this paper proposes a future
mobility in which shared, electric, and autonomous vehicles would be
multi-functional and behave as a collaborative system. In this future, fleets
of multi-functional vehicles would complete different tasks collaboratively,
giving a response to the different urban mobility needs. This paper contributes
with the proposal of a framework for future urban mobility that integrates
current research and mobility trends in a novel and unique way.
