It allows you to control inputs and outputs as you would do with an Arduino, but it has Wi-Fi. The ESP8266 is a Wi-Fi module great for IoT and Home Automation projects. The list of required equipment is as follows:Īdditionally you can add an HC-SR04 Ultrasonic Distance Sensor for free movement of the robot. Since we are using ESP8266, it was necessary to move the robot wirelessly over WiFi, and a simple application was made for this.īasically, the robot has the necessary equipment such as a microcontroller, two step motors, a motor driver and a battery. Robot movements have become more balanced with use of stepper motors. Hobby stepper motors were used instead of DC motors. Thus, the robot was controlled via the internet. Of course, it is possible to make a slight wobble forward and backward from the balance point of view, but this did not hinder the robot's movements.Īlso, a NodeMCU board with ESP8266 chip was used instead of an Arduino microcontroller. So take a look at how it works.Īs you can see the biggest difference compared to other robot cars is that it is built on 2 wheels. While surfing the internet, I saw a 3D car design with a different structure, and I wanted to experience it by making it. Generally, robot cars are built on a chassis with 2 DC motor wheels and a bovine wheel.
