This document describes the design and fabrication of a Bluetooth-controlled butler bot. The bot is intended to help transport food and beverages in a restaurant to improve efficiency. It will use an Arduino UNO microcontroller, L298N motor driver, HC-05 Bluetooth module, batteries, and a 12V DC geared motor. The estimated budget for the components is 3090 rupees. The bot is designed using Fusion360 and a schematic and circuit diagram are provided. The document outlines the aim to build an efficient bot that can be easily controlled to help automate food delivery in restaurants.

3. Introduction
• In this project it is a butler robot which is a robot that can provide services in a
restaurant, like any butler or waiter.
• The robot can move and be controlled through human supervision using a
wireless connection.
• A robot is a prototype that is mechanically and electronically designed and
programmed by computers to perform a particular task.

4. Aim & Objective
• Our aim is to build a efficient Bluetooth controlled Butler bot which helps
to transport Foods & Beverages with simple controls.
• To built a Food Industry Purpose bot which can be controlled by anyone
with less training.
• To improve efficiency by reducing the time for providing foods and
beverages to customers in restaurants.

5. Problem Statement
• Nowadays Food Industry are getting automated to reduce work load
and time to improve efficiency for cooking and delivering foods to the
customers.
• Our Bluetooth Bot will be a great contributor for automation in
restaurants by helping them in distribution of foods by delivering to the
customers.
