ESP32 CAM Solar Robot Car Kit – 4WD Arduino WiFi Camera (Unassembled)

Master Robotics, Solar Energy & IoT in One KitThe ESP32 CAM Solar Smart Robot Car Kit is a complete educational robotics platform that brings together wireless control, computer vision, solar energy harvesting, and autonomous navigation into a single hands-on project. Whether you’re a student taking your first steps in electronics, a teacher building a STEM curriculum, or a maker looking for a weekend project, this kit delivers real engineering concepts through an engaging, build-it-yourself experience.Real-Time WiFi Video StreamingAt the heart of this robot car is the ESP32-CAM module with an integrated camera and external antenna for boosted signal strength. Once connected to your local WiFi network, the car streams live video directly to a web-based interface on your phone, tablet, or PC. There’s no app to install. Just open the browser, enter the car’s IP address, and you have full video feed with directional controls. The external antenna ensures reliable connectivity at distances up to 50 meters, making it practical for indoor and outdoor use.Solar Charging with Intelligent Voltage MonitoringThis kit introduces real-world renewable energy concepts through a 5V 2.5W solar panel mounted on a photosensitive tracking gimbal. The gimbal uses light-dependent resistors to automatically orient the panel toward the strongest light source, maximizing charging efficiency. A built-in digital voltmeter displays real-time battery voltage, and when it drops below 6V, you simply engage the solar charging module to recharge the 18650 battery, protecting it from deep discharge damage.Autonomous Navigation ModesThe car operates in multiple intelligent modes. The ultrasonic obstacle avoidance system pairs an HC-SR04 sensor with a servo motor that scans left, center, and right, calculating distances and choosing the clearest path. This teaches both ultrasonic ranging and PWM servo control. The ultrasonic following mode detects an object in front and maintains a set following distance, moving forward or backward automatically. The three-way infrared tracking module follows black lines on the ground with high precision, requiring no manual calibration out of the box.Expandable & Future-ProofThe control board offers rich expansion interfaces for connecting additional sensors, displays, and modules. Once you’ve mastered the built-in functions, you can extend the car with custom features. Add a buzzer, connect an OLED display, integrate GPS, or write entirely new autonomous behaviors. The Arduino IDE and C language provide a professional programming foundation that scales from beginner experiments to advanced robotics projects.SpecificationsWorking Voltage5VInput Voltage7–9VMax Output Current2AMotor Speed200 RPM at 5VSolar Panel6V / 1WUltrasonic Range2cm – 400cm (<15° angle)WiFi Control Distance10 – 50 metersServo Range0° – 180°Battery Required2× 18650 3.7V (not included)ProgrammingArduino IDE (C language)Dimensions25.5 × 15.5 × 19 cm (approx)What’s in the Box4WD car chassis with geared motors and wheelsESP32-CAM module with ESP32 Cam-MB moduleH-Bridge Motor driverHC-SR04 ultrasonic sensor with servo mount6V 1W solar panel Plate2x LDR moduleDigital voltmeter displayAll cables, screws, and mounting hardware Category: Projects College Road Electronics4.85 (317 Reviews)
