MEMS technology is in almost every smart device around us, ranging from smart watches to cell phones. This lecture will explore fundamental theoretical concepts of navigation with a particular aim towards inertial sensors and dead reckoning.This lecture will cover everything needed to understand what is an inertial measurement unit (IMU) and how it works and what are limitations of such systems. The lecture will cover: Reference Coordinate Frames Accelerometer - Basic Principles Gyroscope - Basic Principles Putting it together in an IMU What is xDOF? Acc + Gyro -> Coordinates Drifts and other demons Practical DemoHaving basic understanding of cartesian coordinates and trigonometry should be sufficient. Don't get scared as elementary school knowledge from 7th grade will suffice for this.
