MECHATRONICS / SELECTED WORK
Hardware I built, systems I modelled and software I made, each with a written case study: the problem, the decisions, the result, and what is still open.
01 / Mechatronics / Degree project
My bachelor’s degree project at KTH: a compact knife sharpener with three abrasive belts in one indexing head and one drive motor shared by all three. I took it from sketches to a prototype that sharpened under supervision.
Prototype built · sharpening demonstrated under supervision02 / Embedded machine learning / Robotics
A small course robot that acts on what its own camera sees: an on-board detector spots a plate, a bucket and an exit arrow, and a state machine decides the next move. Built and debugged; the full mission was not completed.
Built · mission not completed03 / Browser extension / Product engineering
A Chrome extension I built that puts a product’s price history on the product card itself, as five small scores, so you can see whether today’s price is actually good. A personal research prototype on Swedish price-comparison sites.
Personal research prototype04 / Mechanical design / Product Development (MF1045)
A centrifugal clutch that Edvin Börthas and I designed for a go-kart’s drivetrain in KTH’s Product Development course: sized by hand, modelled in CAD and checked in an acceleration model. A design, not a built part.
Designed and simulated · not manufactured05 / Modelling & control / Basic Mechatronics (MF2030)
A nutrunner is a powered tool that tightens bolts to a set torque. In a KTH mechatronics course, three of us modelled one in MATLAB and Simulink, from its motor to the bolt it clamps. A simulation study; no tool was built.
Modelled and simulated · no tool built06 / Robotics / Introduction to Robotics (DD2410)
My work in KTH’s Introduction to Robotics course: a seven-joint arm that reaches a pose, a map built from laser scans, routes a car-like robot can actually drive, and a ROS 2 robot that recovers when it is moved. All in simulation.
Implemented and run in simulation07 / Experience design / Creative development
This site: a small 3D workshop you explore by scrolling, with a full written case study behind every project. I directed and reviewed it; AI coding assistants wrote most of the code. Live since September 2026.
