RoboCar 4.0
A smart robot car controlled in real time over WebSockets — an ESP32 and a Python backend talking JSON to an Arduino, with a live camera stream to the browser.
Outcome
Real-time robot control over WebSockets — ESP32 + Python.
The problem
Build a responsive, low-latency control loop for a physical robot car spanning web, backend and microcontrollers.
Approach
- Controlled the car via an ESP32 and a Python backend on an Elegoo smart-car chassis.
- Used WebSockets for real-time, bidirectional control with a live camera feed in the browser.
- Exchanged JSON messages between the ESP32 and an Arduino, driving the motors through an L298N driver.
Results
- A working real-time control system across the full hardware/software stack.
