about.md
Hey! I'm Luca Obwegs from Italy. I love robots, climbing and learning new things.
I work as a Control Engineer Robotics/Mechatronics in the Mechatronics and Robotics Systems Laboratory at Hilti in Liechtenstein, where I have contributed control software to five robotic and mechatronic prototypes – from modelling and simulation to the implementation on the target hardware and testing on the real system.
In my spare time I build robots, drones and flight instruments from scratch – from the CAD model and the PCB to the software and control algorithms. I take robotics and control algorithms from simulation to reliable C++ code on physical hardware. My projects also include Python-based inverse kinematics and ROS 2 joint-command interfaces.

01 // career & education
Career & Education
Earlier experience
Mechanical-engineering high school diploma, hands-on electrical assembly and soldering, plus summer internships at M2 Railtech working on mechatronic prototypes, microcontrollers and PCB design.
02 // skills
What I work with
Robotics software, kinematics and control, from simulation to hardware integration and testing. Project pages distinguish implemented features from experiments and planned work. Algorithm familiarity is not a claim that every method has been deployed on hardware.
Control & Simulation
Model-based design and state estimation, followed by testing on physical hardware.
Embedded Systems
Real-time control loops on microcontrollers, close to the sensors and actuators.
State Estimation
Fusing noisy sensors into states a controller can rely on.
Robotics & Integration
Connecting models, command interfaces and physical mechanisms.
Hardware
Building the prototypes myself, so the software has something to run on.

Outside the Lab
Climbing in the Dolomites
In 2023, Lucas and I opened Via Eureka: an eight-pitch route on Lagazuoi. Climbing is a personal interest, separate from my engineering work.
