ELEGOO Smart Robot Car Kit V4 with Camera — UNO R3 & ESP32 Wi‑Fi FPV, Line-Tracking and Obstacle Avoidance

This kit combines a ready-to-assemble chassis, an ELEGOO UNO R3 controller, an ESP32 camera/Wi‑Fi module, sensors, motors and a rechargeable battery so beginners and hobbyists can build, program and drive their own robot car. It’s designed for step-by-step learning: keyed connectors and illustrated instructions simplify wiring, example programs illustrate core concepts, and open Arduino IDE compatibility invites creative coding beyond the basics.

How will this kit help me learn robotics and coding?

The kit pairs physical hardware with hands-on programming examples so you can immediately see how code changes affect movement and sensor responses. Example sketches for Arduino IDE demonstrate motor control, sensor reading, and camera streaming; you can edit them to practice logic, timing and conditional behaviors.

• Includes UNO R3 board and ESP32 camera module for real-world input and output.
• Example projects cover line following, obstacle avoidance and FPV streaming.
• Wiring guidance and keyed connectors reduce assembly errors for beginners.
• Open-source-friendly: modify Arduino sketches or upload your own firmware.

What driving modes and sensors are included, and how do they work?

The car supports multiple interactive driving modes: app or IR remote control, automatic line-tracking, and ultrasonic-based obstacle avoidance. The ESP32 camera provides first-person-view video over Wi‑Fi so you can steer remotely while seeing what the car sees.

• Ultrasonic sensor for distance detection and automatic stopping or rerouting.
• Line-tracking sensors detect contrast to follow black or dark lines on a surface.
• IR remote and ELEGOO app allow manual driving and mode switching.
• ESP32 camera streams FPV video to a smartphone or laptop via Wi‑Fi.

How beginner-friendly is the assembly and programming process?

Assembly is intended for learners and classroom use: keyed XH2.54 connectors simplify hookups and the illustrated tutorial walks you from chassis construction to your first powered run. Programming starts with ready-made examples, then progresses to Arduino IDE projects you can tweak to expand functionality.

• Step-by-step illustrated assembly guide for chassis and modules.
• Keyed connectors minimize incorrect wiring and make module swaps easier.
• Beginner example code plus instructions for importing into Arduino IDE.
• Rechargeable battery and included parts make the kit classroom-ready.

What is included in the kit and what additional items might I need?

The kit ships with the main electronics and mechanical parts required to build a functioning robot car: UNO R3 controller, ESP32 camera/Wi‑Fi module, motors, sensors, IR remote and a 2000 mAh lithium-ion battery. You may want a computer with Arduino IDE and a USB cable for programming, plus basic tools such as a screwdriver and wire cutters.

• Included: ELEGOO UNO R3, ESP32 camera, line-tracking sensors, ultrasonic sensor, motors, IR remote, 2000 mAh battery.
• Recommended: PC or Mac with Arduino IDE installed for code editing and uploading.
• Optional: smartphone for FPV viewing and the ELEGOO control app.
• Tools: small Phillips screwdriver and wire cutters for assembly tasks.

Who is this for? The ELEGOO UNO R3 Smart Robot Car Kit V4 is aimed at learners aged 8+ with adult guidance, hobbyists, STEM teachers and coding clubs that want a hands-on platform for teaching electronics, programming and robotics concepts. It suits beginners who need guided assembly and example code, yet also supports intermediate makers who want to customize behavior through Arduino IDE and add new sensors or routines.
