  Nowadays, the Internet of Things (IoT) concept is gaining more and more
notoriety bringing the number of connected devices to reach the order of
billion units. Its smart technology is influencing the research and
developments of advanced solutions in many areas. This paper focuses on the
merger between the IoT and robotics named the Internet of Robotic Things
(IoRT). Allowing robotic systems to communicate over the internet at a minimal
cost is an important technological opportunity. Robots can use the cloud to
improve the overall performance and for offloading demanding tasks. Since
communicating to the cloud results in latency, data loss, and energy loss,
finding efficient techniques is a concern that can be addressed with current
machine learning methodologies. Moreover, the use of robotic generates ethical
and regulation questions that should be answered for a proper coexistence
between humans and robots. This paper aims at providing a better understanding
of the new concept of IoRT with its benefits and limitations, as well as
guidelines and directions for future research and studies.
