Industry 4.0, also called smart industry, is considered the Fourth Industrial Revolution
and seeks to transform each company into a smart organization to achieve the best business
results. It combines advanced production and operations techniques with smart
technologies such as robotics, analytics, artificial intelligence, cognitive technologies,
nanotechnology and Internet of Things (IoT).
Automatic Guided Vehicles (AGVs) are essential for the development of Industry
4.0, that is, for the transformation of the industry through automation and digitization,
to the point that they have revolutionized many of its processes. One of the most common
applications in which AGVs are being implemented is for the movement of goods
in sectors such as food or logistics, preserving productivity and, above all, safety.
AGVs differ according to their guidance systems, a very important element when
setting up in an industry. However, current guidance methods are most mechanical or
laser scanner and its main problem is the low accuracy they can offer. RF technologies
such as RFID, Ultra-wide band or millimeter wave, are currently being investigated to
accurately estimate the position of obstacles and to ensure operator safety.
In this final degree project we have studied the performance of indoor location systems
based on Ultra-wide band and millimeter wave technology so that, they can be
used as a sensing technology in a real security system for AGVs.
This work shows that although there is still a long way to go, both technologies may
be used in the future to estimate the location of objects and people in robot’s vicinity.
In this way, the robot could rectify its path, or in a limit case, stop safely.
