Andrien Robotics is an independent robotics consultancy in the Netherlands, led by Alex Andriën, a specialist in robot estimation, control and deployment. The consultancy helps teams address problems that emerge when robots move from simulation or the lab to real-world operation, including drifting position estimates, unreliable sensor fusion and controllers that fail when conditions change.

Its services cover estimation and sensor fusion, such as GPS-denied and GNSS-degraded navigation, and the design and tuning of extended Kalman and complementary filters combining IMU, GPS and vision data. Andrien Robotics also develops and improves controllers for physical systems, including model predictive control, nonlinear trajectory optimization and Lyapunov-based tracking. For teams facing deployment delays, the consultancy diagnoses faults in hardware and code, restores a working system and hands it back to the client.

Clients include drone and UAV companies, mobile robot builders, robotics startups, research institutes, medical robotics teams, defense organizations and system integrators.
