  "Smart cities" is the trendy rubric of modern urban projects that require new
innovative ideas to attain the desired perfection in many fields to change our
life for the better. In this context, a new innovative application will be
presented here to investigate and continuously make the required maintenance of
public roads by creating a flying robot for painting the partially erased parts
of sidewalks' edges that are usually plated in two different colors; primarily
black and white as we suppose here. The first contribution of this paper is
developing a fuzzy-logic-based stabilization system for an octocopter serving
as a liquids transporter that could be equipped with a robot arm. The second
contribution consists of designing an embedded energy harvester for the flying
robot to promote the management of available power sources. Finally, as
suggested in this project, we present a complement heuristic study clarifying
some main concepts that rely on a computer vision-based decision-making system.
