8. Existing method Existing methods for controlling robots often rely on traditional remote controls, Bluetooth modules, or direct wired connections to an Arduino microcontroller unit (MCU). These approaches have several drawbacks. Wired connections limit the robot's range of movement and flexibility, making it cumbersome for practical use. Bluetooth-based systems, while wireless, suffer from limited range and potential interference from other devices, reducing reliability. Additionally, traditional remote controls lack the intuitive and hands-free operation provided by voice commands. These limitations highlight the need for a more advanced solution, such as a Wi-Fi based voice control system, which can offer greater range, flexibility, and user-friendly interaction. 03-06-2024 8

9. Problem statement Existing robot control systems often rely on manual input methods, limiting their usability and accessibility. Additionally, traditional control interfaces may not be suitable for users with disabilities or those in environments where manual interaction is impractical. There is a need for a more intuitive and user-friendly control system that can enable seamless interaction with robots, particularly in scenarios where hands-free operation is essential. 03-06-2024 9

11. Proposed method The proposed method for developing a voice-controlled robot using Wi-Fi, based on an Arduino microcontroller unit (MCU), involves several key components and steps. Firstly, a voice recognition module captures the user's voice commands, which are then processed and converted into digital signals. These signals are transmitted over a Wi-Fi network to the MCU. The Arduino, programmed to interpret these commands, acts as the brain of the robot. It sends appropriate signals to a motor driver, which serves as an intermediary between the MCU and the motors. The motor driver amplifies these signals to control the power delivered to the motors, ensuring precise movements of the robot. The robot's motors, which are responsible for its locomotion, execute actions such as moving forward, backward, turning left, and right, based on the commands received. This method leverages Wi-Fi for remote operation, allowing the robot to be controlled from a distance, enhancing its usability and versatility in various applications, including home automation and industrial tasks. The integration of these components ensures a seamless and responsive voice-controlled robotic system. 03-06-2024 11

16. DC Motor A machine that converts D.C power into mechanical power is known as a d.c. motor. Its operation is based on the principle that when a current carrying conductor is placed in a magnetic field, the conductor experiences a mechanical force. The direction of this force is given by Fleming’s left hand rule and magnitude is given by; F = BIl newton’s Basically, there is no constructional difference between a D.C. motor and a D.C. generator. The same D.C. machine can be run as a generator or motor. 03-06-2024 16

17. 12V battery A rechargeable battery is an energy storage device that can be charged again after being discharged by applying  DC  current to its terminals. Rechargeable  batteries  allow for multiple usages from a cell, reducing waste and generally providing a better long-term investment in terms of dollars spent for usable device time. This is true even factoring in the higher purchase price of rechargeable and the requirement for a charger. A rechargeable battery is generally a more sensible and sustainable replacement to one-time use batteries, which generate current through a chemical reaction in which a reactive anode is consumed. The anode in a rechargeable battery gets consumed as well but at a slower rate, allowing for many charges and discharges. 03-06-2024 17
