Pi 5 Acoustic Robot Localisation Kit
Pi 5 Acoustic Robot Localisation Kit – Real-Time Sound-Tracking Robot
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Give your robot the ability to hear and orient toward sound, just like a living creature. This kit uses a four-microphone array and Raspberry Pi 5 to compute time differences of arrival, making the robot rotate to face claps, voices, or any acoustic event in milliseconds. The result is a responsive wheeled platform that demonstrates core concepts of AI robotics – all on a single fast processor.
What You'll Build
A self-contained wheeled robot that continuously listens through its ReSpeaker 4-Mic HAT and instantly turns toward any detected sound source. The real-time TDOA algorithm, running on the Pi 5’s Cortex-A76 cores, calculates azimuth angles and drives the motors through the Cytron driver to smoothly orient the chassis. Whether it’s a clap from across the room or a voice command, the robot stays locked on target, giving you a tangible foundation for advanced audio-driven automation.
What You'll Learn
- Compute sound direction using time difference of arrival (TDOA) with a 4-mic array
- Configure and capture multi-channel audio on Raspberry Pi 5 with the ReSpeaker HAT
- Drive DC motors via Cytron motor driver using PWM and direction control
- Integrate sensing, processing, and actuation into a real-time robotic system

Who This Kit Is For
Ideal for B.Tech ECE and CSE students exploring embedded AI, especially for Smart India Hackathon challenges involving sensor fusion. CBSE Class 11–12 innovators at ATL Tinkering Labs will find it a powerful demonstration of real-time signal processing, and university teams from IIT, NIT, and VIT can adapt it into advanced robotics coursework. If you have basic Python and Linux skills and want to see AI interact with the physical world, this kit delivers.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The AI companion walks you through each step with visuals and code snippets; if you still need help, message us on WhatsApp and we’ll guide you personally within hours.
How accurate is the sound localisation?
The 4-mic array provides a bearing accuracy of about 5–10 degrees in typical indoor environments, depending on ambient noise and distance to the source.
Can I modify the code to track only a specific sound, like claps?
Yes, the open-source Python signal processing chain can be tuned to filter for impulse sounds such as claps or sustained tones like a whistle; the companion AI will help you adjust thresholds.
Is this suitable for a science exhibition or hackathon?
Absolutely. The real-time demonstration of TDOA-based robot orientation is a show-stopper at science fairs and hackathons; many students have won awards with similar projects.
Microphone array on Pi 5 performs TDOA sound source localisation — robot turns to face sound source in real time.
