RPA og prosessledelse : En eksplorativ studie av RPA-implementering i norske bedrifter
2020
Master's thesis in Information systems (IS501) Bakgrunnen for denne utredningen har vært å undersøke om det er en sammenheng mellom Robotic Process Automation (RPA) og Business Process Management (BPM), samt hvordan norske virksomheter nyttiggjør seg av dem. I de siste årene har det i økende grad blitt populært å ta i bruk RPA for å automatiseredeler av bedrifters prosesser. Utover dette vet vi veldig lite om hvilke erfaringer virksomheter har med denne teknologien. På den annen side har vi BPM, et konsept som har blitt forsket på i flere år.Samtidig finnes det lite forskning som tar for seg både RPA og BPM. På bakgrunn av dette gjennomførte vi en forstudie høsten 2019. Her gjorde vi flere …
Condition monitoring of steel wire ropes
2018
Master's thesis Mechatronics MAS500 - University of Agder 2018 By utilising the measurements from a commercial acoustic emission sensor system, magnetic tester and a camera system, conducted during four separate simple bending fatigue tests of steel wire ropes (SWR), several measurable quantities of the SWR which indicate deterioration were identi ed. Based on the measurements of a commercial acoustic emission sensor system of one of the tests in this thesis, the fatigue process of a SWRs in a simple bending test is three-phase, with a relatively long rstand second phase, showing little- and steady increase in activity, respectively, followed by a shorter phase with a ramp up of activity. T…
Modeling, Simulation and Control for Marine Crane Operations
2020
Master's thesis in Mechatronics (MAS500) Marine cranes play an important part in offshore operations. They are expected to perform awide range of different tasks, such as handling the load safely offshore. Nowadays, the offshoreoil fields and wind farms are detected and developed, thus more and more offshore platforms arebuilt. The scale and capacity of crane vessels are developing rapidly to fulfill the construction needof offshore platforms and offshore wind farms. Heavy crane, placed on-board vessel, is affected byvessel motions induced by environmental forces such as wind, waves and current, and vice versa.Therefore, the investigation of coupled dynamics between heavy crane and vessel, …

Model-free object grasping : Model-free object grasping with a learning-free approach
2021
Master's thesis in Mechatronics (MAS500) The industry standards and capability are constantly advancing and pushing forward to increase data collection, efficiency, profit, and quality as well as decrease downtime, injuries, and hazards as much as possible. In recent years, robot systems have received more attention in the context of a large number of industrial applications, such as automotive manufacturing, additive manufacturing, assembly, quality inspection, and co-packing. The collaboration between multiple robots and human operators is considered to be the most prominent strategy in Industry 4.0 and future Industry 5.0, sharing the same space and collaborating on tasks according to th…
Autonomous Pick-and-Place Procedure with an Industrial Robot Using Multiple 3D Sensors for Object Detection and Obstacle Avoidance
2021
Master's thesis in Mechatronics (MAS500) This thesis proposes a full pipeline autonomous pick-and-place procedure, integrating perception, planning, grasping and control for execution of tasks towards long term industrial automation. Within perception, we demonstrate the detection of a large object (target) including position and orientation (pose) estimation in 3D world. Further on, obstacles in the work area are mapped with proposed filtering prior to motion planning and navigation of an industrial robot to the target’s pose. The target is then picked using a custom built motorized 3D printed end gripper, and placed at a desired location in the robot’s reachable environment. Point cloud b…
Towards Data-Driven Modelling of Saulekilen Wastewater Treatment Plant based on Artificial Intelligence
2019
Master's thesis Mechatronics MAS500 - University of Agder 2019 The processes at a wastewater treatment plant (WWTP) are complex systems thatclean the wastewater before it is released into the environment. Total phosphorous(TP), biological oxygen demand (BOD) and chemical oxygen demand (COD) arecritical measurements of the water quality. Measuring BOD and COD are too slowto effectively control the wastewater treatment processes (5 days and a couple ofhours respectively) as the wastewater treatment process at Saulekilen WWTP usesabout 30-40 minutes from influent to effluent. Measurements of effluent TP are alsoperformed and are quicker but controlling by the use of effluent TP is too slow. He…
Miniature Fish Respirometry System with Integrated Cameras
2021
Master's thesis in Mechatronics (MAS500) A respirometry system for small fish up to 30 mm in length has been developed and a prototype has been produced to verify the design. The developed system has two integrated cameras for top and side filming of the specimen during testing. The report details the development of an axial impeller pump based on a theoretical pump head loss analysis of the system and max flow velocity of 20 cm/s. A PI regulator has been implemented to accurately control the rotational velocity of the impeller. Control software for the operation of the respirometry system has been conceptualized and partly implemented.
Pose Estimation of Drilling Pipe Using a 3D-Sensor Network
2019
Master's thesis Mechatronics MAS500 - University of Agder 2019 In this thesis, a pose estimation system for drill pipe-ends has been made. The systemutilizes 6 sensor nodes containing a Kinect v2 RGB-D camera in addition to a Jetson TX2computer. Pipe detection is done on 2D images from each camera using Tiny-YOLOv3.A pair of point clouds for the box-end and pin-end are made based on these detections, inaddition to the depth map which the Kinect provides. Further segmentation is done, andpose estimation using ICP is performed.When the pipes are placed on the ground and placed vertical at a minimum distance of5.5m away from the sensors, the system achieves a mean positional accuracy of≈2.6cm,…
Simulation and Control of an Anti-Swing System for a Suspended Load attached to a moving Base Robot
2018
Master's thesis Mechatronics MAS500 - University of Agder 2018 Advanced motion compensation is an important eld of engineering in today's o shore industry. Performing advanced load handling operations at sea requires high attention to both safety and e ciency. In environments governed by wave motion and harsh weather conditions, these types of operations are complex tasks. Most of the load handling scenarios are performed by advanced o shore loader cranes, where many of these are equipped with the industry's state-of-the-art Active Heave Compensation. This technology is capable of compensating for the wave height disturbance, meaning that the load is kept at a constant height above the sea …
