ESP32 WiFi Robot Car Kit - Build a Phone-Controlled 4WD Vehicle
ESP32 WiFi Robot Car Kit - Build Your Own Phone-Controlled 4WD 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.
Imagine controlling a four-wheeled robot across your floor using just your phone's browser - no remote, no app install. This ESP32 Mini Robot Car Kit puts that power in your hands. You assemble the compact 4WD chassis, wire the motors and dual L298N drivers, and program the ESP32 to host a web page that lets you steer forward, reverse, left, and right via WiFi.
What You'll Build
A high-torque, four-wheel-drive robot car that responds instantly to your smartphone. With the ESP32 as its brain, you'll have a complete mobile platform that navigates tight spaces, pivots on the spot, and can later be customized for line-following, obstacle avoidance, or sensor-based autonomy.
What You'll Learn
- Programming the ESP32 as a WiFi web server with HTML, CSS, and JavaScript controls for real-time motor commands.
- Interfacing two L298N motor drivers to independently control four TT gear motors with PWM speed regulation.
- Building a dual-voltage power system using 18650 cells, an LM2596 buck converter, and 1N4007 diodes for clean 5V and motor supply.
- Debugging microcontroller circuits, reading driver datasheets, and using decoupling capacitors to reduce electrical noise.

Who This Kit Is For
Ideal for CBSE Class 11-12 students exploring IoT and robotics, first-year B.Tech ECE/EEE learners tackling internal projects, participants in Smart India Hackathon building quick prototypes, and ATL Tinkering Lab innovators who need a compact, WiFi-driven platform. It bridges textbook theory and practical control engineering.
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?
Scan the QR code to chat with the AI companion, which walks you through wiring, code upload, and debugging in real time. Or reach us on WhatsApp - a human engineer responds within business hours.
Do I need to install an app to control the car?
No. The ESP32 creates its own WiFi network and serves a control webpage. Just connect your phone to that WiFi and open a browser - no installation required.
Can I reuse the ESP32 for other projects later?
Absolutely. The ESP32 is reprogrammable over USB, and all components are standard modules. After building the car, you can repurpose the board for countless Arduino or MicroPython projects.
Why are there diodes and capacitors in the kit?
The eight 1N4007 diodes protect against reverse current and back-EMF from the motors. The 100nF capacitors suppress high-frequency noise, ensuring stable readings and reliable WiFi connectivity during motor switching.
Compact 4WD chassis with ESP32 controlling four motors. WiFi web page drives the car from phone browser.
