Hospital Sanitization Robot

Project Title

Hospital Sanitization Robot

Project Area of Specialization RoboticsProject Summary

COVID-19 forced the global norms to be inverted. This dreadful pandemic bound people to their homes as it was transmitted from one person to another. The staff in our hospitals play a crucial role in order to clean and sanitize units, but in this way, they are not guarded and are in direct contact with the infected people. The current scenario requires that the hospital staff be prevented from getting the disease, and for that purpose, we are introducing a hospital sanitation robot. This project emphasizes the line following technique as the robot follows a specific path and senses if the bed is empty. It sanitizes the area, and if not, it moves to the next bed. Furthermore, it also applies the obstacle avoidance technique. If a person comes in front of it, the stops and rings an alaxrm until the obstacle moves from in front of it. This robot will not only solve the problem of contact-free service but also help in controlling the spread of disease.

Project Objectives

•  Enhance our Team Work skills
• Enhancement of Time management skills
• Enhance our programming skills
• Enhancement of electrical as well as mechanical skills
• Successfully design out robot
• Successfully design our robots working methodology
• Successful implementation of the circuit
• Ensure the proper working of  the robot
• Finalizing its body structure

Project Implementation Method

Our main consideration for this design were maximizing effectiveness and minimizing the cost. With this mind, we prioritized the design of our robot. Firstly we designed its main body structure, while designing it our main goal was that it should have the strength to carry some weight. As it would have to carry the sanitizing pump and a generous amount of sanitizing liquid. To ensure this we used aluminum as the main material for the body, as it can bear a lot of weight without bending. After the designing of the body structure we had to attach motors to it so that our robot can move on its specified path. In order to achieve this we used 4 gear motors with 100 rpm each. While connecting the motors we faced some holding issues related to motors and tires as well. For this purpose we had to design a separate holder for each motor in order to minimize its vibrations. After connecting the motors we started implementation of line following technique using specific sensors. This technique will allow the robot to move on its specified path. After its successful implementations we moved towards the implementation of obstacle avoidance technique using separate components and sensors. When both of these techniques were implemented successfully our robot was now ready to move without any collision. After achieving the successful movement of our robot, now the time was to implement its main working process which was sanitization of the beds. Each bed was given a different barcode number, robot will scan the barcode number through RFID in order to stop when it reaches near the bed. After successful implementation of scanning process now was the time to use pressure pump for sanitization of the beds. 

Benefits of the Project

Along with large scale commercial application like hospital sanitization, this robot can also be used in smaller scale applications such as home cleaning robot.

Benefits of hospital sanitization robot:

• Proper sanitization of the hospital beds.
• Remote and wireless operation ensures workers aren’t put in danger.
• Obstacle avoidance to minimize collision.
• Reduced spread of diseases through proper sanitization.
• This robot has a compact, portable and user friendly design.
• Reduces manpower.

Technical Details of Final Deliverable

Our robot starts working with a manual input. As soon as the input is given to the processor, our robot starts moving towards the specified path. It will follow the specified path with the help of the line following technique, which is implemented through arduino controller, in which the code for line following and path following will already be integrated. While moving on the specified path with the help of the line following technique, our robot will also follow obstacle avoidance technique using ultraviolet sensors to avoid hindrance in the path, any human contact or any hurdle that comes in its specified path. If our ultraviolet sensor detects any hurdle or obstacle in its path, the code integrated into the controller will automatically stop the movement of our robot to avoid any collision. Once the UV sensor detects any hurdle, our robot's movement will be stopped. The UV sensor will keep on sensing till it detects no hurdle or obstacle on the specified path to continue the movement of the robot. When the UV sensor detects no hurdle, the movement of the robot will be resumed and the robot will keep on following the path follower technique to remain on the given path. When our robot reaches near the beds in the hospital wards, it will read the bar codes integrated into the beds. Once it reads the bar code, it will sense if there is a patient on the bed through image sensing. If the image sensor detects no human on the bed, then our robot will sanitize the whole bed through a sanitizing pump in the form of liquid spray. If the sensor detects any human body on the bed, then our controller will order the robot to skip the sanitization process on this bed and move towards the next bed and repeat the same process of detection of a human body on the bed.
