Lärande i ljuset av kunskapens användning

Bidraget vill påvisa vikten av arbetsintegrerat lärande. Detta görs genom att redovisa resultat från en kurs på masternivå som använder pedagogiken genom att blanda det industribaserade projektarbetets pedagogik med universitetets teoretiska bas så att studenterna förstår sambandet mellan teori och praktik och får öva sin analytiska och logiska problemlösningsförmåga

Identifying Improvement Areas in Production Planning Meetings by Assessing Organisation and Information Systems at a Small Production Company

The increased mass-customisation of production requires operators to manage an increasing number of complex work tasks. From a social sustainability perspective, better sharing and dissemination of production information supports operators cognitively to manage and understand their work tasks, which in turn improves quality of work. So, the focus of this paper is to study how production planning meetings can be improved. Previous research suggests that the MEET model can be used as a framework for improving meetings and information sharing by studying 10 different areas within a company’s Organisation System (OS) and Information System (IS) whilst considering the time and place prerequisites and aims for these meetings. In this paper, the applicability of the MEET model and its 10 areas are tested at a small production company by applying two different approaches. First, a questionnaire was presented to and filled out by a manager, the results of the questionnaire identifies the improvement potential of each of the 10 areas. Second, a comprehensive current-state analysis based on observations on the shop-floor and interviews with operators were carried out with regards to the 10 areas. The results from these two approaches were compared and the comparison showed that both approaches point towards similar areas for potential improvements. This paper concludes that the MEET model can be used as a general framework to inspire change by suggesting areas with potential improvement in information sharing. While the selfassessment questionnaire can identify a direction, additional information and involvement of other stakeholders are recommended for actual implementations of change. For future research, the methods based on the MEET model will be further developed to improve accuracy and the suggestions provided to the case company in this paper will be tested as a validation of the model

Novel trends in the assembly process as the results of human – the industrial robot collaboration

The contribution is focused on the creation of an idea proposal and simulation of the assembly system in cooperation of the human and the industrial robot. The aim of the research is to verify the feasibility of this cooperation between the human and the industrial robot on the basis of the created simulation in the assembly process. The important step of the design this collaboration is the determination of rules and safety of this cooperation. The paper also presents the method of working with the selected software and its functionalities and sequence of steps at the simulation creation. The objective of the research is the evaluation of the idea proposal of the collaborative assembly system on the basis of the created simulation. The analysis and evaluation of the simulation confirm the feasibility and safety of the cooperation of the man and robot and also verified the possibility of assembly made by man and robot from the disposition and dimension on point of view of the proposed workplace

Evaluating Cobots for Final Assembly

AbstractCollaborative robots becomes more and more common in lab environment and soon also in industry. In order to create resource- and volume flexibility, dynamic and smart automation could be seen as an answer. This paper has investigated the collaborative robots UR3 and UR5 for O-ring assembly and final assembly, compared to the current state which is performed manually. The methodology Dynamo++ was used for measurement and analysis in terms of LoA (cognitive and physical), cycle-time and quality. Furthermore, automation strategy, safety and easiness of programming was investigated. Results show that collaborative robots have great potential in the middle product volume area. A lot of time, layout space and money could be saved with these solutions. However, standards and safety has to be investigated further in order to reach its fully potential

Discussions include base concepts and enabling technologies for the development of human-automation symbiosis work systems in Industry 4.0

MEETINGS – THE INNOVATIVE GLUE BETWEEN THE ORGANISATION SYSTEM AND INFORMATION SYSTEM

The research presented aims for enhanced utilization of human skills, collaboration, and information sharing. This paper concerns the production context, and the needs and challenges of people striving for high-quality, innovative, and efficient work. The paper presents a model of the information system (IS) and organisations system (OS) and their integration. Main conclusions are that these systems overlap, and create an innovative working arena for the different working processes. People with knowledge gather into meetings held for different purposes supported by technical systems. These meetings provide a core element for efficient and innovative collaboration, requiring parallel development of IS and OS

Context-dependent multimodal communication in human-robot collaboration

In the dynamic environment of human-robot collaboration, a key for boosting the efficiency of human workers is supporting them with context-dependent work instructions, delivered via communication modalities that suit the actual context. Workers, in turn, should be supported in controlling the robot or other components of the production system by using the most convenient modality, thus lifting the limitations of traditional interfaces as push buttons installed at fixed locations. We introduce a workflow for context-dependent multimodal communication in a collaborative work environment and present its implementation in a Human-Machine Interface Controller system

Variations in cycle-time when using knowledge-based tasks for humans and robots

Operator4.0 was coined in 2016 to create a research arena to understand how the physical, cognitive, and sensorial capabilities of an operator could be enhanced by automation. To create an interaction between operator and robots, there are important factors that needs to be defined. Two important factors are the task and function allocation. Without well-defined tasks it is hard to allocate the tasks between the robot and the human to create resource flexibility. Furthermore, it the tasks are knowledge-based rather than rule-based, the cycle time between operators can differ a lot. Two assumptions are discussed regarding knowledge-based tasks and automation. These are also tested in an experiment. Results show that it is a large variation of the cycle time for both humans (between 1,58 minutes up to 4,40 minutes) and robots (between 1,94 minutes up to 4,49 minutes) when it comes to knowledge-based and machine learning systems.CC BY-NC-ND 4.0The authors will give their deepest gratitude to VINNOVA for founding the projects FAKTA, TACO and National testbed which this study is a result in.</p

Robotic Label Applicator: Design, Development and Visual Servoing Based Control

Use of robotic arms and computer vision in manufacture, and assembly process are getting more interest as flexible customization is becoming priority over mass production as frontier industry practice. In this paper an innovative label applicator as end of arm tooling (EOAT) capable of dispensing and applying label stickers of various dimensions to a product is designed, fabricated and tested. The system incorporates a label dispenserapplicator and had eye-in-hand camera system, attached to 6-dof robot arm can autonomously apply a label sticker to the target position on a randomly placed product. Employing multiple advantages from different knowledge basis, mechanism design and vision based automatic control, offers this system distinctive efficiency as well as flexibility to change in manufacturing and assembly process with time and cost saving
