    Safety-Focussed Design of Collaborative Assembly Station with Large Industrial Robots2018Inngår i: Procedia Manufacturing, Elsevier B.V. , 2018, s. 503-510Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The perceived benefits of large industrial robots for collaborative operations are characteristics such as long reach with heavy load carrying capability. Collaborative operations refers to situations where operators and robots share a workspace to complete tasks in close proximity. This mode of operation coupled with the physical characteristics of large robots represents high risks to injury and for these reasons, the safeguarding of the workspaces needs to be achieved in conjunction with the tasks to be performed within the workstation. This article will detail two workstations that was developed in a laboratory environment and are partial results of a research project titled ToMM2, whose aim was to understand safety issues associated with collaborative operations with large robots.

    Safe Assembly Cell Layout through Risk Assessment - An Application with Hand Guided Industrial Robot2017Inngår i: Procedia CIRP, vol. 63, Elsevier B.V. , 2017, s. 430-435Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Risk assessment is a systematic and iterative process which involves risk analysis where the probable hazards are identified and corresponding risks are evaluated along with solutions to mitigate the effect of these risks. In this article the outcome of a risk assessment process will be detailed where a large industrial robot is being used as a intelligent and flexible lifting tool that can aid operators in assembly tasks. The realization of a collaborative assembly station has several benefits such as increased productivity and improved ergonomic work environment. The article will detail the design of the layout of a collaborative assembly cell which takes into account the safety and productivity concerns of automotive assembly plants.

    Virtual Verification of Human-Industrial robot Collaboration in Truck Tyre Assembly2015Inngår i: Proceedings 19th Triennial Congress of the IEA, 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Human-industrial robot collaboration has been introduced as the ultimate combination for industry. The endurance and strength of a robot is combined with a human’s flexibility, precision and quality skills. One challenge in the implementation of human-industrial robot collaboration is to create a safe working station for the operators, therefore most of the research focuses on these safety aspects. Industrial designers and engineers verify and optimise workstations in different simulation and visualisation tools in order to improve competitiveness, reduce late changes and reduce cost. Several robot tools and digital human modelling tools are available, but there are no or few simulation and visualisation tools that include both humans and robots. The aim of the proposed paper is to illustrate how unique software can be used to verify human-industrial robot collaboration. This software is a combination of the robot simulation tool IPS and the digital human modelling tool IMMA. The software demonstration is promising, covering the gap between digital human modelling tools and robot simulation tools. The simulation and visualisation tools generate pictures and animations, as well as quantified numbers to aid well-founded decision-making. The demonstration software was used to analyse a truck tyre assembly station. Fully manual, fully automated and human-industrial robot collaboration were compared.

    Practitioner Summary: The presented paper illustrates simulation and visualisation software for the virtual verification of Human - Industrial Robot collaboration. The software demonstration is a combination of the robot simulation tool IPS and the digital human modelling tool IMMA. The software demonstration is promising, covering the gap between digital human modelling tools and robot simulation tools.

    Simulation and evaluation of industrial applications of Human-Industrial Robot Collaboration cases2015Inngår i: Nordic Ergonomics Society 47th Annual Conference NES 2015, 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Presented in this paper are two cases from a heavy vehicle manufacturer which demonstrate the potential width of Human-Industrial Robot Collaboration workstations. Case I simulates in machining environments, the assisted inspection of inline engine blocks and Case II simulates in logistics environments, the assisted material preparation for assembly line orders. The analysis and simulations were carried out with a software tool that combined digital human modelling, robotic simulation, path planning and use of technical computing tools. Results demonstrate the improvement of process ergonomics and cycle time.

    Designing workstations for human–industrial robot collaboration: Development and application of simulation software2020Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Human-industrial robot collaboration (HIRC) creates an opportunity for an ideal combination of human senses and industrial robot efficiency. The strength, endurance and accuracy of industrial robots can be combined with human intelligence and flexibility to create workstations with increased productivity, quality and reduced ergonomic load compared with traditional manual workstations. Even though multiple technical developments of industrial robot and safety systems have taken place over the last decade, solutions facilitating HIRC workstation design are still limited. One element in realising an efficient design of a future workstation is a simulation software. Thus the objective of this research is to (1) develop a demonstrator software that simulates, visualises and evaluates HIRC workstations and (2) propose a design process of how to apply such a simulation software in an industrial context.

    The thesis comprises five papers describing the development of a HIRC simulation software and its corresponding design process. Two existing simulation software tools, one for digital human modelling and one for robotic simulation, were merged into one application. Evaluation measures concerning operation time and ergonomic load were included in the common software. Existing engineering design methods were applied in a HIRC workstation context to describe the utilisation of a HIRC simulation software. These developments were demonstrated in five actual industrial cases from a heavy vehicle manufacturing company.

    The HIRC simulation software developed enables simulation, visualisation and evaluation of all kinds of HIRC workstations where human and robot simultaneously work in a collaborative environment including hand-guiding tasks. Multiple layout alternatives can be visualised and compared with quantitative numbers of total operation time and biomechanical load on the human body. An integrated HIRC workstation design process describes how such a simulation software can be applied to create suitable workstations. This process also includes a safety measure by which the collision forces between the industrial robot and the human are predicted. These forces have to be minimised to tolerable limits in order to design safe HIRC workstations.

    The HIRC simulation software developed and the proposed workstation design process enable more efficient HIRC workstation design. The possibility of designing and evaluating HIRC alternatives for hand-guiding activities is rarely found in other simulation software. The evaluation could include different types of layout alternatives and workstations: HIRC, fully manual or fully automatic. All of these could be compared based on their total operation time and biomechanical load and thus be used in workstation design decision making.

    Verification of quantitative human–industrial robot collaborative simulation results2016Inngår i: Swedish Production Symposium 2016 SPS 2016, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Human–industrial robot collaboration (HIRC) is introduced to make future industrial workstations more ergonomically viable and productive. A HIRC simulation software demonstrator based on the simulation software Intelligently Moving Manikin (IMMA) has been recently developed. The simulation and visualisation tool uses mathematical algorithms to predict human and robot motions. Data from the human motion are used to assess the biomechanical load exposure. The validity of the simulated motions considering biomechanical load have not yet been verified. Thus, the aim of this study is to verify the biomechanical load predicted by the HIRC demonstrator simulation software through laboratory experiments. A HIRC workstation for engine block inspection was used for the evaluation, where a family of physical and virtual humans performed the inspection. The physical tests were performed in a lab environment, and the virtual tests were simulated in the HIRC simulation software. In both tests, data of human motion were captured. The joint angles of the body parts were extracted and analysed to assess biomechanical load using rapid upper limb assessment (RULA). A comparison between the results of the laboratory experiment and the simulation test shows that the simulated human movements of the HIRC workstation correspond well with humans performing the same task in the lab environment.

    Human Industrial Robot Collaboration – development and application of simulation software2015Inngår i: International Journal of Human Factors Modelling and Simulation, ISSN 1742-5557, Vol. 5, nr 2, s. 164-185Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Human industrial robot collaboration (HIRC) aims to combine the benefits of industrial robots with humans in production environments. This is a growing research field where most work focuses on the safety aspects, while little research is performed on simulation and visualisation. The aim of this paper is to present a demonstrator software for simulation, visualisation and evaluation of human industrial robot collaboration.

    Two simulation software products were combined to reach this goal. The new tool was then applied to two industrial assembly cases where productivity and biomechanical loads on humans were calculated. The resulting demonstrator software simulates and visualises human industrial robot collaboration. The quantitative output from the simulation makes it possible to compare HIRC, manual and robotic assembly stations in terms of productivity and ergonomics.

    Virtual evaluation of industrial human-robot cooperation: An automotive case study2014Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The manufacturing industries in the developed countries face challenges in terms of increased competition that puts demands on productivity, and a demographic change leading to an older population. One way of managing these challenges is through closer cooperation between human operators and robots. The robots can perform heavy, repetitive and hazardous tasks in a workstation, while the human operator does the more complex and flexible operations.

    Most industrial human-robot interaction research focuses on the safety aspects, often performed and presented in the form of physical demonstrators, while little research is made on virtual simulations. Several simulation and visualisation tools for robot evaluation exist, as well as tools for digital human modelling. However, few tools can be found that virtually combines human and robot.

    The aim of this paper is to contribute to narrowing that gap by presenting a method for virtual evaluation and optimisation of industrial human-robot cooperation. The new software demonstrator developed for this is based on the DHM tool IMMA. The presented method was implemented in a truck industry case comparing three assembly scenarios; fully manual, fully robotised or human-robot cooperation assembly. The method considers three dimensions which are compared and optimised for the human and robot; reach, operation time and biomechanical load.

    The software demonstrator presents a virtual simulation of industrial human-robot cooperation. The result from this simulation can be used to find the optimal ergonomic manufacturing system based on biomechanical loads as well as finding the system with shortest operation time. The specific industrial case verifies the statement that a human-robot collaborative assembly system gives a less physically demanding workstation compared to a manual system, and thus is better adapted to an elderly workforce. This is achieved at the same time as the operation time decreases and productivity increases, which is necessary to meet the global competition. There are though safety issues to be solved and safety standards to be changed before these benefits can be applied in practise in industry. However, the software can be used to analyse different kind of human-robot interactions that are less cooperative and can be implemented within current regulations.

    Automation constraints in human–industrial robot collaborative workstation design2016Inngår i: Swedish Production Symposium 2016 SPS 2016, 2016Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Human–industrial robot collaboration (HIRC) aims to combine desired characteristics of humans and industrial robots – the flexibility, intelligence and tactile sense of humans, and the strength, repeatability and accuracy of robots. A newly developed demonstration software enables simulation, design, verification, optimisation and visualisation of HIRC workstations. Two parameters, operation time and biomechanical load, are measured as quantitative outputs. These parameters favour fully automatic workstations since industrial robots move faster than humans without biomechanical restrictions. However, there exist limitations in the automation possibilities in workstation design. The aim of this paper is to define automation constraints and include them in the task allocation process of HIRC workstations. This will give a more accurate process in task allocation between humans and industrial robots in a HIRC workstation design problem. Three previously performed simulations of industrial HIRC cases from a heavy vehicle manufacturer are used as a basis in order to identify automation constraints in the task allocation process. Four criteria that limit automation possibilities are identified, human cooperation, dual operation, manual quality control and inaccurate positioning of objects. These constraints are included in the work method of task allocations in HIRC workstation design.

    Implementing Virtual Assembly and Disassembly into the Product Development Process2013Inngår i: Enabling Manufacturing Competitiveness and Economic Sustainability: Proceedings of the 5th International Conference on Changeable, Agile, Reconfigurable and Virtual Production (CARV 2013), Munich, Germany, October 6th-9th, 2013, Springer International Publishing , 2013, s. 111-116Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Virtual assembly and disassembly (VA&D) usage enables knowledge exchange between design department and assembly production and aftermarket in the product development (PD) process. Utilisation of VA&D tools must be connected to the PD process in robust methods to fully employ this potential. A case study was performed at a manufacturing company to identify virtual activities and their position in the PD process. Assembly production and aftermarket departments have common demands on the utilisation of the VA&D tools in the PD process. Milestones that demands VA&D simulations shall be included in both concept phase and development phase in the PD process.

    Method for Design of Human-industrial Robot Collaboration Workstations2017Inngår i: Procedia Manufacturing, ISSN 2351-9789, Vol. 11, s. 4-12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In order to fully utilise a 3D simulation software capable of evaluating hand-guided human-industrial robot collaborative (HIRC) work tasks, there is a need of a HIRC design process for early production development stages. This paper proposes a HIRC design method that uses the possibilities of the demonstrator software in the HIRC workstation design process. The method is based on Pahl and Beitz's engineering design method; it interprets all their phases and activities into HIRC design-specific ones.

    Human Industrial Robot Collaboration – Optimisation of Handover Position2015Inngår i: 2015 IEEE/RSJ International Conference on Intelligent Robots and Systems, Hamburg, Germany, September 28 - October 02, 2015., 2015Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The simulation possibilities of Human Industrial Robot Collaboration (HIRC) are limited in commercial software and published research. In order to meet this a demonstrator software has been developed. This paper presents the combination of the quantitative output from the software (measuring operation time and biomechanical load) together with optimisation techniques used to design the optimal HIRC workstation. An industrial case is used as an example where the optimal geometric handover position between robot and human is found. From the simulation software metamodels were created in order to represent the investigated workstation. The model was used in a multi-objective optimisation problem and resulted in a trade-off chart between operation time and biomechanical load. The result shows one example of the possibilities to combine the quantitative results from the simulation with optimisation in order to get the best solution to a HIRC design problem.

    Simulation methodology for performance and safety evaluation of human-industrial robot collaboration workstation design2019Inngår i: INTERNATIONAL JOURNAL OF INTELLIGENT ROBOTICS AND APPLICATIONS, ISSN 2366-5971, Vol. 3, nr 3, s. 269-282Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is a strong interest in the scope of human-industrial robot collaboration (HIRC) in manufacturing industry for greater flexibility and productivity. However, HIRC in manufacturing is still in its infancy; industrial practitioners have many apprehensions and uncertainties concerning the system's performance and human operators' safety. Therefore, there is a need for investigations into design processes and methods to make sure the designed HIRC workstations successfully meet design guidelines on system performance, human safety and ergonomics for practical industrial applications. This research proposes a HIRC workstation design process. The novelty of this design process is the methodology to evaluate the HIRC workstation design alternatives by considering both performance and safety characteristics through computer-based simulations. As a proof of concept, the proposed HIRC design process is applied on an industrial manufacturing case from a heavy-vehicle manufacturing company.
