Smart indoor objects delivery system
Project Area of Specialization Internet of ThingsProject SummaryThe delivery systems, specifically, the automated objects delivery robots are widely demanded by erudite people due to their convenient use, safety, reliability, and optimized delivery. These robots not only serve as elderly assistants but also replace the manual delivery of goods in offices and other places. Addressing the inconsistencies which are resulted because of human errors and increased labor costs in manual delivery, this research aims to automate the task of objects delivery within a small or medium-scale building, also to facilitate the employees and workers of indoor environments. The sender and receiver of objects, communicate with each other using the Android application. The proposed delivery robot takes input from the keypad and navigates within a specified indoor area by implementing the Line Following technique based on the IR sensors interfaced with ESP 32 microcontroller. In addition to this, it eschews the obstacles in its path using an Ultrasonic sensor and detects the destination location using the color sensor. Upon reaching the destination, the fingerprint scanner is used for the verification of the receiver. After successful delivery, the robot returns to its home location following the same line. In case, if the robot faces robbery such that it is picked up from the ground, the camera module captures images of thieves. These images are being received by the person sending the robot whereas a notification is sent to the receiver of objects through the designed Android application.
This prototype helps to deliver the objects in a more secured fashion by the implementation of dual verification. Furthermore, the delivered objects reach the destination efficiently within the indoor environment, unlike human delivery which can be time-consuming and tedious. The proposed system can be used for various medical, educational, as well as industrial purposes.
Project ObjectivesThe project aims to propose a robotic model which is expected to deliver the daily used objects from one place to another in an indoor environment. This robotic system is interfaced with the mobile application through which the communication between sender and receiver of objects is carried out. The designed application also contains an additional security feature of receiving captured thief images.
The main objectives are:
- To propose a robotic prototype to carry regularly used objects in indoor areas.
- To design and develop a mobile application using Android Studio / MIT App inventor.
- To develop an interface between the Android application and the delivery robot.
- Analysis and comparison of our designed robotic model with already existing delivery robots.
The project methodology is comprised of seven modules which are described as under:
Module 1: The Movement of the robot.
Description: The robotic prototype is programmed in a way so that it moves between two specified locations following a black-colored line using IR sensors.
Module 2: Obstacle avoidance.
Description: The robotic prototype avoids static obstacles in its path by sensing them using Ultrasonic sensors.
Module 3: Color detection for verification of destination.
Description: The proposed robot detects colored papers representing the destination locations using the TCS34725 color sensor and stops at the location specified by the sender of the robot.
Module 4: Input provision and receiver confirmation.
Description: The robotic system takes input from the sender of the robot using the 3x4 input keypad and the receiver of objects is authenticated at the destination location through his/her fingerprint.
Module 5: Implementation and testing of the camera module.
Description: The proposed robotic prototype senses the irregular vibrations using the SW-420 vibration sensor and captures images of muggers using ESP 32 CAM. The arrangement of this apparatus is tested for its proper functionality.
Module 6: Design and development of Android application.
Description: The Android application is developed so that the sender and receiver of the delivery robot can communicate with each other regarding the delivery time and the items to be delivered. The images of thieves are also received at the sender’s side.
Module 7: Integration of application with the robot and testing the system.
Description: The designed Android application is integrated with the robot through Firebase real-time database such that the images captured by the camera module are stored in the database and are retrieved by the application. Later the whole system is collectively tested to achieve accuracy.
Benefits of the ProjectThe major benefits of the project are listed below:
- The proposed robot helps in reducing the usage of large delivery vehicles which are the source of traffic congestion and emit greenhouse gases due to more miles traveled.
- It provides safer delivery of goods such as food in restaurants; cushions, bed covers, and luggage in hotels; test samples, and medicines in hospitals; and stationery objects in educational institutions such as files, notebooks, multimedia projectors, etc.
- It reduces the overall labor cost as compared to manual delivery.
- It saves a lot of time as the goods are transferred immediately without roaming around the building to receive them.
- It helps in retrieving goods without being in direct contact with the other person, thus contactless delivery is achieved.
- Our delivery robot can be one of the best products to invest in, to provide automatic delivery of goods in various sectors of Pakistan as there are very few places where robots are used for carrying and delivering goods.
The final deliverable is in the form of a robotic prototype along with an Android application. This robotic model can carry small to medium-sized regular use objects with a maximum weight of 10 kilograms. Furthermore, the proposed robotic model can make the delivery within an indoor environment for up to 2-5 kilometers. Also, it can climb the slope having a height of 24 inches and an angle of 140-142 degrees with the ground. The direction of travel of the robot is determined by the black line. The initial robotic operation can be viewed from the link given below:
Delivery Robot-First Test video
The designed Android application is comprised of a user interface that asks the receiver to enter the details of the object to be delivered and the required delivery time whereas the sender enters the estimated delivery time which will be sent as a delivery confirmation message to the receiver. In addition to this, the application is integrated with the robot in such a way that the captured images of thieves using a camera module, are received by the sender of the robot, and a notification message is sent to the receiver notifying him of the robbery.
