The Wi-Fi talking robot is a robot that can communicate with users over a Wi-Fi network. It uses a combination of hardware components, such as a microcontroller and Wi-Fi module, and software programs to process user commands and generate appropriate responses. The robot's ability to connect to a Wi-Fi network allows it to receive commands from users remotely, enabling it to perform various tasks and interact with users from a distance. This robot consists of Bluetooth speaker module to ask for what we want.   The controlling device of the whole system is a NodeMCU module. The ESP8266 based NodeMCU development board. It is an open-source platform for developing Wi-Fi based embedded systems and it is based on the popular ESP8266 Wi-Fi Module, running the Lua based NodeMCU firmware. One of the easiest ways to program NodeMCU is via the Arduino IDE   4 BO motors along with L298n motor driver is interfaced to the NodeMCU. When the user presses the button from IOT app. The Nodemcu as inbuilt Wi-Fi module so it receives the data from app and control the robot accordingly. When the user asks the question from bluetoth app, this data received by Bluetooth speaker module and gives the appropriate voice through speaker.

 

 The objectives of the project include:

• Controlling robot from app using IOT technology.
• VOICE Communication using Bluetooth technology and google assistant.
• Using NodeMCU module to achieve this task.

The main building blocks of the project are:

• NodeMCU.
• L298N motor driver.
• 4 DC Motors.
• Bluetooth speaker module.
• Battery power supply.
• Robot body.

Software’s used:

1. Arduino ide studio compiler to write the program.
2.  Express SCH for Circuit design.

Technologies used:

1. Bluetooth technology.
2. IOT technology.
