Today, most of the test operations at the Final Assembly Line (FAL) involve the use of paper and manual operations, like work orders, test results, etc. In the case of troubleshooting tasks or in cases where expert assistance is required, people must be physically at the workplace to collaborate efficiently. The use of Augmented Reality and IIoT is being used more and more in other industries to tackle the problems aforementioned in a more sophisticated way. The introduction of AR in the aeronautic sector is challenging, but itâ€™s becoming more a more real (for example) in the manufacture of cable harnesses. Project ARIESS goes a step further by introducing AR in the fuselage of the aircraft, where mobility is a tight restriction.
Another challenge tackled by ARIESS is the development of situational awareness in a complex workplace like the FAL. The use of technologies like IPS, besides to AR, contributes to improving orientation in the workplace and makes it easier for the workmen to move around. Generally, workmen require the use of charts to move around in the factory plant, to locate tools or equipment and to find for example specific assembly compartments. Both Augmented Reality and Indoor Positioning System are technologies that will be integrated into a portable platform with wireless connectivity to get access to a local Network, taking advantage of the IIoT. Deploying a secure, reliable and manageable network is the third challenge of ARIESS.
The three technologies envisioned by Project ARIESS for the Final Assembly Line of an aircraft are described in more detail in the following paragraphs, together with the role that they play in the Project.
-Augmented reality (AR). In ARIESS it is planned to develop a hands-free HMI, based on augmented reality glasses and Bluetooth headphone and microphone that will be connected to the information systems of the factory using a communication middleware, and will make use of the localization information to represent the required information and the right moment and place.
-Indoor positioning system (IPS). One key type of information to be handled by the HMI developed in this Project is the localization information, not only of the operators but also of the robotic systems, portable devices, and tools. This localization information, along with a direct communication with the information systems (like CAD/CAM, work orders, etc.), will allow presenting the required information adapted to the specific operation that they have to perform. This information will not only have to be presented on a mobile device (which is already solved with the current technologies), but also to visualize this information on the appropriate place which implies to know the location of the operator at each moment and use augmented reality techniques to present the information on the right place.
-Industrial Internet of Thing. The development of novel visualization tools (using augmented reality and simulation technologies) requires the development of new communication architecture and middleware that integrate in an effective way the information distributed in the factory. This information ranges from the Enterprise Resource Planning (ERP) systems and the Manufacturing Planning and Control systems (SAP) to the workshop level (robotic systems, tools, etc.) and the management of the knowledge acquired within the processes. The creation of ubiquitous systems is one of the technologic challenges that will allow the engineers to control the production and detect, measure and monitor events, variables or conditions that affect the productivity of the production systems at a factory and process level.
\"So far, the work done in the Project has been oriented to the generation of the States of the Art for both Work Packages WP1 and WP2 and the definition of the use cases for these WPs.
Regarding to the State of the Art for HMI and IPS a review about the technologies Indoor Positioning and Navigation Systems, Augmented Reality COTS and SDKs and Speech recognition techniques and tools were carried out. After analysing these systems and equipment, it has been concluded that the optimal solution to integrate into ARIESS will not be the use of only one of them, but the integration of several working together.
Regarding to the State of the Art for Connected Factory, Wireless Sensor Networks (WSN) for factory applications were described.. The objective is to provide the analysis of the wireless interconnection techniques and standards that are currently in use in WSN in factory automation in order to best select the approaches that will be adopted in ARIESS Work Package2 \"\"CONNECTED FACTORY\"\".
Moreover, there is a preliminary document with the high level requirements for the selected use cases. The TM has been in close contact with the Project Coordinator for these tasks.
The expected results and potential impacts are those in the original proposal, for the current stage of the Project.
ARIESSS introduces a number of innovations in the Final Assembly Line of an aircraft that makes a qualitative difference with respect to the current processes and methodologies. The
solution proposed is a step forward in the degree of technification of the modern FAL, in areas with a lot of room for improvements like functional tests of fixtures or parts in the aircraft and MRO operations.
ARIESS will be a leap forward in functional tests and other tasks in the FAL with regard to lead time, recurring costs and also flexibility and transparency. The main contribution of the technologies addressed in ARIESS is to contribute and speed up the introduction of automation in aircraft manufacturing and thus to the identified challenges: Reduction of Production Cost, Improved Quality and Reliability, Better Floor Space Utilization, Reduce Waste, Stay Competitive.
