Eco: Energy visualization & machine cycle detection
By Bitz Gaëlle
Systems Engineering - Infotronics
Focus: Sustainable Energy Systems
Summary: This thesis develops a machine cycle detection algorithm and a dashboard for real-time energy visualization at Constellium Valais. The system collects energy data via OPC-UA, processes it with machine learning algorithms, and detects machine cycles in homogenization ovens. A Python-based dashboard using Plotly Dash displays consumption trends. Synthetic data supplements real datasets. The project enhances energy efficiency, supporting peak load reduction and operational optimization.

BLE2ROS
By Samy Francelet
Systems Engineering - Infotronics
Focus: Robot Communication
Summary: The BLE2ROS thesis focuses on integrating Bluetooth Mesh Networking with the Robot Operating System (ROS) through a gateway. The gateway consists of an ESP32 microROS node and an nRF53 BT Mesh Provisioner. The microROS node bridges data between the Mesh network and ROS, while the Provisioner manages Mesh nodes and relays sensor data. The proof of concept demonstrates feasibility but faces limitations due to microROS bugs and BT Mesh’s low data rate. Key deliverables include source code, a working demonstrator, and a technical report.

Real-time line crossing detection
By Aurélien Rithner
Systems Engineering - Infotronics
Focus: Computer Vision
Summary: This project develops a real-time camera-based system to detect when a vehicle crosses track limits during the Summer School I race. Using Python, OpenCV, and Django, it processes video feeds, extracts race data, and visualizes results on a web dashboard. A proof-of-concept with fixed cameras was tested, with an optional drone-based solution explored. Machine learning approaches were investigated but deprioritized due to time constraints. The system ensures accurate, automated race tracking.

NetPrinting Wireless Identification
By Adrien Rey
Systems Engineering - Infotronics
Focus: Embedded Systems
Summary: This thesis develops a secure Bluetooth Low Energy (BLE) authentication system for Polyright’s NetPrinting solution. It enables smartphone-based authentication for printers, replacing RFID cards. The system includes a middleware web service, a mobile app (React Native), and a BLE-enabled card reader (TWN4). AES-128 encryption ensures security. A proof-of-concept test bench validated feasibility. The project enhances digital identification while maintaining compatibility with Polyright’s ecosystem.

Modeling of Cable Cars for Energy Consumption Optimization
By Adrien Azzalini
Systems Engineering - Power&Control
Focus: Modelisation
Summary: This project models cable car energy consumption using a real-time simulator to optimize operations. Sisag AG, a Swiss company specializing in cable car control systems, seeks strategies to reduce energy use. A parametric simulation tool was developed and validated with real-world data, achieving ±5% accuracy. By dynamically adjusting speed based on passenger flow, the study suggests potential energy savings of 20-35%, improving efficiency while maintaining service quality.

Robot SCARA
By Yohan Aymon
Systems Engineering - Power&Control
Focus: SCARA Robot
Summary: This thesis improves a SCARA robot initially developed in 2020, optimizing its mechanics, motor control, and user interface. The system, designed for precise 2D drawing, now features enhanced structure, reduced mechanical play, and an improved motorized gripper. A Siemens PLC controls movements via TCP/IP communication with a PC-based interface. The software includes motion planning and trajectory optimization, ensuring smooth and accurate operation. The upgraded robot serves as a demonstration tool for automation.

Development of an ANPC Inverter Control System for Photovoltaic Integration
By Daniel Héritier
Systems Engineering - Power&Control
Focus: Power Electronics
Summary: This thesis develops a control system for an Active Neutral-Point Clamped (ANPC) inverter to integrate photovoltaic panels or other DC sources into the power grid. The system employs space vector modulation (SVPWM) and pulse-width modulation (PWM) techniques for efficient energy conversion. Simulations in PLECS and Typhoon HIL validate system performance. Safety mechanisms protect against failures, ensuring reliable operation. The study enhances renewable energy integration through optimized inverter control.

Modernisation and optimisation of a test bench for Nammo
By Cyril Pitteloud
Systems Engineering - Design&Materials
Focus: Testbench
Summary: This project automates Nammo’s manual leak test bench to enhance efficiency and accuracy. The new system utilizes a hydropneumatic cylinder, applying 30-bar pressure to test component seals. Operators simply place a part, press start, and view results on a screen. The redesign reduced testing time by 20 seconds per cycle while improving reliability. The test bench ensures repeatable quality control, integrates safety features, and supports future scalability in production.

Design, Manufacturing, and Testing of a Counter-Rotating Microturbine for Pressure Reduction in Drinking Water Networks
By Daniel Biner
Systems Engineering - Design&Materials
Focus: Hydropower Plants
Summary: This project focuses on designing, manufacturing, simulating, and testing a counter-rotating microturbine for energy recovery in drinking water networks. A MATLAB tool calculates turbine wheel geometries, which are transferred to CAD for modeling and CNC machining. Performance tests showed a simulated efficiency of 83%, but real tests achieved only 53% due to gap losses. The project establishes a functional process, forming a basis for future turbine geometry optimizations to enhance efficiency.
