Robotized semiautomatic motorcycle transmission development. Electronic and software design
In this paper, we propose an electrical design (implemented on a PCB board) and an accompanying software design for controlling the automatic gear change. The designs complement the mechanical solutions developed in Part 1. The paper also analyses the issues encountered during the intermediate steps of the development of the electronic module, which is expected to be small and adaptable enough to be installed on a motorcycle without changing its ergonomics. The control software runs on the Arduino Nano board and is built as a state machine with one idle state, five active states that cover different stages of the gear change and one error state for preventing malfunctions in case of an unex…

Academia-industry Collaboration for Augmented Reality Application Development
Abstract Due to our previous experience in AR development, with this research project we propose to study how Augmented Reality (AR) can be adopted by an industrial partner and which are the major outcomes from which a company may benefit. For this purpose, we partnered with a forward-looking company willing to embrace the idea of implementing new technologies for industrial purposes. In this research we identified that the most significant impact which AR may have for our industrial partner is in providing remote assistance and for product exploitation and marketing purposes. For the latest we developed a customized AR application which is currently available on Apple’s App Store. By analy…
Augmented Reality Applied in Machining Processes and Cutting Tools Management
This paper describes the benefit obtained from implementing a cutting tool management system. Also, a state of the art on tool management systems available on the market is presented. By analysing the drawbacks generated by the implementation of such a system, we are providing a cheap and practical solution: an Augmented Reality aided machining and tool management system. Using augmented reality we managed to improve the tool management systems by providing, at the scene of action, all the necessary tool information in a much more user friendly way.
When industry and academia meet: the development of a robotized semiautomatic motorcycle transmission
Abstract The development of the business - industry environment is unconceivable without the involvement of academia. On one hand, the universities can provide new perspectives and know-how which can be further translated into exquisite products and services for companies. On the other hand, the business environment can raise practical problems and challenges for academia, providing in the same time material support for finding solutions to these problems. This paper presents a successful partnership between business and academia materialized in the development of a robotized semiautomatic motorcycle transmission. Since the solutions existing on the market did not meet the specific requirem…
Study Regarding the Optimal Milling Parameters for Finishing 3D Printed Parts from ABS and PLA Materials
Abstract In this paper we proposed to identify the optimum milling parameter required for finishing processes performed on 3Dprinted parts from ABS and PLA materials. We have identified the optimum milling parameters for a constant spindle speed of 3500 rot/min for face milling and profile contouring operations with different tools diameters. The study was performed on 3D printed specimens from ABS and PLA materials.
Key factors towards a high-quality additive manufacturing process with ABS material
Abstract Additive Manufacturing technologies have gained a lot of popularity during the past years. The current challenge being the transition of this manufacturing technology from prototype oriented towards mass production. In order to achieve this, fabrication times and mechanical parameters must be improved. This paper aims to identify which are the parameters that have the highest influence on parts obtained with fused deposition modeling (FDM) technology from ABS material. In addition, this study identifies which are the most accurate methods to test the mechanical properties of FDM parts while still respecting ASTM standard for testing the tensile properties of plastics. It was found …
Correlation of Vertebral Absolute Axial Rotations in CAD 3D Models of Adolescent Idiopathic Scoliosis Non-Invasively Diagnosed
This paper presents preliminary results on non-invasive optical diagnosis of patient with adolescent idiopathic scoliosis (AIS) with recently developed tool ScolioSIM. This tool generates intrinsic and extrinsic indicators of the spinal deformity and 3D CAD (Computer-aided Design) deformity model based only on a digitalized dorsal surface of the examined patient. Our primary focus in this paper are absolute axial rotations (AAR) of each vertebra in AIS patients and their correlations. Clinical relevance of this research is high, as we intend to avoid traditional methods which rely on highly complicated reading and measuring of AARs on planar x-ray films, as these methods involve ionizing ra…
Main Requirements of a Cyber Physical Production System Demonstrator
Abstract The paper is focused on identifying the main requirements for developing a CPPS demonstrator prototype. This research aims to categorize the main components and interactions within a new manufacturing system which are required to accommodate a CPPS. The proposed CPPS demonstrator also includes the preliminary requirements identified from the discussions with the regional industry, so that the prototype of the production system could be easily understood and also be the basis for further collaborations. The identified requirements were structured according to the top-down principle focusing on accomplishing the major objectives to be achieved through the prototype of the production …
Augmented Reality Applications in the Transition Towards the Sustainable Organization
Business companies are increasingly aware that the world where they operate in is facing increasing environmental, economic and social challenges, thus there is a trend in most companies to align their processes and services with a sustainability agenda. Customers, shareholders, financial partners, governmental agencies, NGOs, globalization and internationalization of environmental and social standards exert new pressures on them to do so. Industry is widely recognized as being essential for wealth creation and development, although it is at times considered a source of environmental degradation and social concerns. Thus, industry must play an important role for the transition towards the s…
Formwork application optimization by using augmented reality
By using the PLM (Product Lifecycle Management) principle on the formwork case study, after determining the functions and the technical solutions, the application must be made as optimum as possible in order to assure productivity and provide the necessary information as quick as possible. The concept is to create a complex management for the formwork based on augmented reality. By taking into account the development rate of the information, augmented reality is tending to be one of the widest (in term of domain) visualization instrument. Also used in the construction domain, augmented reality can be applied also for the case of formwork design and management. The application of the solutio…
Customizable Patient-Specific Cutting Guide for High Tibial Osteotomy
Abstract The paper is an interdisciplinary medical and engineering approach that aims to optimize the accuracy of the High Tibial Osteotomy surgical intervention. The axial deviations of the human inferior limb are presented in the first part of the paper. Without altering the shape of the bones, these deviations cause the wear of the knee’s articular cartilage by gonarthrosis. One of the most common and effective treatment modalities for eliminating axial deviations is High Tibial Osteotomy. Because the surgical procedure involves 3D spatial bone cutting, the accuracy of the procedure and thus the success of the operation and the recovery of the patient is dependent on the execution of the…
Supporting Diagnosis and Treatment of Scoliosis: Using Augmented Reality to Calculate 3D Spine Models in Real-Time - ARScoliosis
Scoliosis is a complex spinal disorder that mostly affects adolescents and younger population. To avoid and reduce harmful radiation techniques in adolescent idiopathic scoliosis investigation and follow-ups, a novel non-invasive approach is highly recommended and needed in clinical practice.
