Design of a virtual robot cell at IKEA Industry : Digital twin of a packaging robot cell

Larsson, Kevin, Winqvist, Max January 2022 (has links)
This report studies how a digital twin can be utilized through offlinerobot programming and simulation for a robot packaging line;additionally, the advantages and challenges of a robot digital twin arereported. This thesis project and the robot simulation is done incollaboration with Ikea Industry.The obtained result was in form of a digital twin which is a digital copyof a physical robot cell at Ikea Industry’s packaging line. The resultsshow that a digital twin can indeed be utilized for layout planning androbot optimization. An energy consumption chart which depends on thetime taken to package ten boards was created. This chart can be used forfurther optimization of the robot cell.The study also shows that a digital twin can save time and money,especially in the design phase, for medium to small companies that donot have the resources to create a dedicated physical robot cell fortesting.

Mitigation of Background Harmonic Amplification at PCC Using Active Filtering of STATCOM

Malki, Luai January 2017 (has links)
Shunt compensation devices have been a powerful candidate for expanding the limits of transmission facilities, allowing more active power transport and supporting voltage and overall stability of the network. An example of such devices is the Static Synchronous Compensator (STATCOM) which is based on Voltage Source Converter (VSC) which synthesizes output voltage and current for mainly reactive power compensation. STATCOMs might be accompanied with a Thyristor Switched Capacitor (TSC) or Reactor (TSR) which are controllable shunt devices for extra VARs required, along with passive filters for absorbing the switching harmonics generated by the VSC. Such STATCOM topology is referred as the Hybrid STATCOM.However, such configuration typically results in parallel resonances with the maingrid’s passive elements at different harmonic frequencies. This leads to amplification of background harmonics, if any exist, at the Point of Common Coupling (PCC) where the Hybrid STATCOM is connected. This thesis deals with the VSC control in the STATCOM to mitigate the harmonic amplification behavior by active filtering,which is based on emulating an impedance by the control. Also, the overall system passivity is essentially studied, which ensures a passive system with respect to harmonics. / Shunt-kompensationsanordningar har varit en kraftfull kandidat för att öka gränserna för överföringsanläggningar, vilket möjliggör högre aktiv effekt och understöderspännings-stabilitet och övergripande stabilitet i kraftnätet. Ett exempel på sådana enheter är Static Synchronous Compensator (STATCOM) som är baserat på Voltage Source Converter (VSC) som syntetiserar utspänning och ström för huvudsakligen reaktiv effektkompensation. STATCOMs kan åtföljas av en Thyristor Switched kapacitor (TSC) eller Reaktor (TSR) som är kontrollerbara shunt-apparater som ökar kapaciteten för reaktiv effekt (VARs), tillsammans med passiva filter för att absorbera övertoner som genereras av VSC. Sådan STATCOM-topologi kallas HybridSTATCOM. Emellertid, en sådan konfiguration resulterar i parallella resonanser med huvudnätets passiva element vid olika övertoner. Detta leder till förstärkning av bakgrundsövertoner, om någon existerar, vid Point of Common Coupling (PCC) där Hybrid STATCOM är ansluten. Denna avhandling behandlar hur VSC kontrolleras i STATCOM för att mildra förstärkningen av nivåer för övertoner genom aktivfiltrering, vilket är baserat på att VSC kontrollen emulerar en impedans. Dessutom studeras övergripande systempassivitet, vilket säkerställer ett passivt system med avseende på övertoner.

Robotic 3D Printing of sustainable structures / Robot 3D-printing med hållbara strukturer

Alkhatib, Tammam January 2023 (has links)
This bachelor thesis aims to integrate and evaluate a 3D printing robotic cell at the SmartIndustry Group – SIG lab at Linnaeus University (LNU).A sustainable structure consisting of wood fiber polymer composites was 3D printed withan industrial robot. Sustainable 3D printing material can be recycled or burned for energyafterwards. The 3D printing material used in this thesis stems from certificated forests. The objective is to utilise this technology in manufacturing courses and research projectsat the SIG lab at LNU. This objective is achieved by creating an operation manual and avideo tutorial in this thesis.The integration and evaluation process will involve offline robot programming,simulation, and practical experiments on the 3D printing robotic cell.
