Objective (1) Understand the principles of the ultrasonic Doppler effect and its application in speed measurement. (2) Design and build an ultrasonic Doppler speedometer to measure the velocity of a moving object. (3) Analyze experimental data and improve measurement accuracy. 2. Principle The ultrasonic Doppler effect states that when ultrasonic waves encounter a moving target (such as a small car or fluid), the frequency of the reflected wave shifts. The freque...")

The collected sensor data will be processed to determine the attitude angles (roll, pitch, and yaw) of the system. The project will include sensor calibration, data filtering (e.g., complementary or Kalman filter), and real-time angle computation for accurate motion tracking applications.")
