Experimental results with varied positions of obstacle show the flexibility of the robot to avoid it and have shown a decent performance and it is getting a communication range of nearly 50m, which is good enough for many surveillance applications. The camera is attached to the wifi robot link which enables it to capture the environment or any object of concern. The four wheeled dc motors help to navigate the robot and ultrasonic sensor to avoid obstacles. The robot can be controlled based on visual feedback from the same smartphone. The app allows you to control an ESP32-Cam based robot car over Wifi (AP/STA. The camera on the robot is used to capture and record real time video from the robot. This app is designed to make it easy for you to build a basic Wifi robot car with live video streaming (camera view). The robot can be remotely controlled using the wifi module and a microcontroller, smart phone interface embedded on the robot. However, the building cost for the robot with a smartphone is greatly reduced. Simply connect it to a computer with a USB cable or power it with an AC adapter or battery to get started. ![]() ![]() It contains everything needed to support the microcontroller. This can be leveraged upon through the use of APIs (Application Programming Interfaces) that is provided for the operating system. The Arduino UNO WiFi Rev.2 has 14 digital input/output pins5 can be used as PWM outputs6 analog inputs, a USB connection, a power jack, an ICSP header, and a reset button. Step 1: Parts You'll Need Arduino (ANY BOARD\ any development board you'd prefer) Selfie stick remote Any transistor // I've used BC547 npn Transistor Buy electronic components at Ask Question Comment Download Step 2: Principle Well the selfie stick remote controls Phone Camera using Bluetooth technology when a button is pressed. ![]() Smartphones come with superb hardware that satisfies the above needs. The robot consists of a video camera and wifi robot link. We developed a sustainable surveillance robot that is cost effective using an Arduino microcontroller together with a motor shield and an Android smartphone that runs the Operating System.
