Hands-free wearable system for helping in assembly tasks in aerospace
Las operaciones de mantenimiento
tienen un gran impacto en la seguridad
y esperanza de vida de cualquier
producto, especialmente en ciertas
aplicaciones dentro de la industria
aeronáutica que tiene que pasar
procedimientos muy rigurosos de
seguridad. Los sistemas de ayuda
llevables (wearable) pueden ayudar
a reducir costes y tiempo de trabajo
guiando a los operarios en tareas
difíciles. El propósito de este trabajo
es presentar un sistema de guiado de
manos libre y llevable para soporte
y ayuda de operarios en tareas de
ensamblaje y verificación dentro del
campo de la aeronáutica. El operario es
capaz de pedir información al sistema
sobre una tarea específica de un modo
no invasivo así como pedir asistencia
técnica al líder del equipo. El sistema
desarrollado ha sido probado en una
compañía aeronáutica (Airbus Military)
y se ha evaluado su implementación
en ciertas tareas de ensamblaje. La
conclusión de las pruebas ha sido
que el sistema ayuda a los operarios a
realizar sus tareas de una manera más
rápida, precisa y segura.Maintenance operations have a great
impact on the safety and life expectancy
of any product. This is especially true
for certain applications within the
aerospace industry, which must pass
rigorous security checking procedures.
Wearable helping systems can help
to reduce costs and working time by
guiding workers in some specifi c and
diffi cult tasks. The purpose of this work
is developing a handless and wearable
guided system that supports and helps
workers in assembly and verifi cation
tasks within the aeronautic fi eld. The
worker is able to request information
for the specifi c task in a non invasive
way and also ask the Team Leader
for real time technical support and
assistance. The system developed has
been tested in an aeronautic company
(Airbus Military) and its implementation
in specifi c assembly tasks assessed. It
was found that the proposed system can
help workers to make their tasks faster,
more accurate and more secure

A systematic review of augmented reality applications in maintenance
Augmented Reality (AR) technologies for supporting maintenance operations have been an academic research topic for around 50 years now. In the last decade, major progresses have been made and the AR technology is getting closer to being implemented in industry. In this paper, the advantages and disadvantages of AR have been explored and quantified in terms of Key Performance Indicators (KPI) for industrial maintenance. Unfortunately, some technical issues still prevent AR from being suitable for industrial applications. This paper aims to show, through the results of a systematic literature review, the current state of the art of AR in maintenance and the most relevant technical limitations. The analysis included filtering from a large number of publications to 30 primary studies published between 1997 and 2017. The results indicate a high fragmentation among hardware, software and AR solutions which lead to a high complexity for selecting and developing AR systems. The results of the study show the areas where AR technology still lacks maturity. Future research directions are also proposed encompassing hardware, tracking and user-AR interaction in industrial maintenance is proposed
