  Swarm robots, which are inspired from the way insects behave collectively in
order to achieve a common goal, have become a major part of research with
applications involving search and rescue, area exploration, surveillance etc.
In this paper, we present a swarm of robots that do not require individual
extrinsic sensors to sense the environment but instead use a single central
camera to locate and map the swarm. The robots can be easily built using
readily available components with the main chassis being 3D printed, making the
system low-cost, low-maintenance, and easy to replicate. We describe Zutu's
hardware and software architecture, the algorithms to map the robots to the
real world, and some experiments conducted using four of our robots.
Eventually, we conclude the possible applications of our system in research,
education, and industries.
