ESP32 Voice Controlled Robot Car Kit — Build a Fully Offline Voice Robot with Edge Impulse

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine a robot that listens only to your voice, follows your commands, and never needs Wi‑Fi or a cloud server. This kit turns that idea into a working prototype in a single afternoon. You'll collect voice samples, train a keyword spotting model in Edge Impulse, and deploy it on the ESP32‑S3 — all processing happens on the chip, so the car moves forward, back, left, right, or stops entirely offline. It’s a hands‑on way to experience real‑world TinyML, perfect for CBSE Class 11‑12 AI practicals, ATL tinkering labs, or any young maker curious about embedded intelligence.

What You'll Build

A 2WD robot car that obeys spoken commands without any internet dependency. The I2S microphone captures your voice, the ESP32‑S3 runs a small neural network that recognizes five keywords, and the L298N motor driver translates those commands into motion. You’ll end up with a fully functional voice‑controlled vehicle you can demonstrate, tweak, and show off at your next science fair or hackathon.

What You'll Learn

• Record and label audio data to build a custom speech dataset
• Design and train a keyword spotting neural network in Edge Impulse
• Export a TensorFlow Lite model as an Arduino library for the ESP32‑S3
• Interface an I2S microphone and a motor driver board for real‑time, low‑latency control

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

CBSE Class 11‑12 students diving into AI and machine learning practicals will find a ready‑to‑run project that matches the curriculum’s emphasis on real‑world applications. B.Tech ECE and CSE undergrads at IITs, NITs, VIT, or BITS can use it for embedded systems labs or Smart India Hackathon prototypes. ATL Tinkering Labs and hobbyists who have tinkered with Arduino will discover how to bring voice control onto a small, low‑power device without relying on a phone or cloud API.

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.
