Sound source localization with head movement

In my master’s program at TUM, I developed a system for a robot to localize sound sources and rotate its head accordingly. Using two microphones to simulate ears, I captured audio, converted analog signals to digital, and implemented algorithms for sound localization. I then generated PWM signals to control the actuators for precise motor control.

This project encompassed key areas of knowledge:

• Low-level Programming: Hardware control in assembly language.
• Microcontroller Programming: Real-time management of sensors and actuators.
• Signal Processing: ADC and sound localization.
• Control Systems: PWM signal generation for motor control.
