Components used ESP8266(1 as server and 1 for each bot) L298N Motor Driver(1 for each bot) Voltage Regulator(1 for each bot) Switch(1 for each bot) Servo Motor(1 for each bot) Speed Motor Sensor with encoder disk(2 for each bot) Bo motor(2 for each bot) Wheels(2 for each bot) Communication System ESP-NOW communication protocol to send data from one ESP32 to multiple ESP32 or ESP8266 boards (one-to-many configuration). The boards was programmed using Arduino IDE. One ESP32 to multiple ESP32 or ESP8266 boards using ESP-NOW (one-to-many configuration). One ESP32 acts as a sender; Multiple ESP32 or ESP8266 boards act as receivers. We tested this setup with two ESP32 boards and one ESP8266 board simultaneously. You should be able to add more boards to your setup; The ESP32 sender receives an acknowledge message if the messages are successfully delivered. You know which boards received the message and which boards didn’t; You need to upload a slightly different receiver code depending ...
