## Summary

Tony Rios, Director of Engineering at MEMSIC, discusses the evolution of inertial measurement units (IMUs) from expensive, large-scale systems to affordable, MEMS-based devices. He explains the mathematical challenges of sensor fusion, specifically using Kalman filters to combine data from accelerometers, gyroscopes, magnetometers, and GPS to estimate position and orientation. Rios highlights MEMSIC's new IMU380 product line, which offers high-quality inertial navigation in a tiny form factor at a low price point, targeting applications like drones and IoT.
