Project Summary

Robotics is a rapidly growing domain of artificial intelligence that is widely used for space, underwater, logistics, medical, agricultural, and military purposes. Technology is evolving so rapidly that there is the continuous replacement of jobs done by humans with machines. Current efforts are to emulate human intelligence and vision in machines so that they can perform tasks with their own artificial senses. There has been a need for disinfection upgrades in hospitals and areas of enclosed spaces too. The act of sanitization is performed by a human who has to wear additional protective clothing to avoid exposure to disinfectants as it is dangerous to human health. This task is perhaps not hectic, but a person has to go through the hassles of wearing a heavy suit and carrying spray for disinfection. The motivation for an autonomous robot for disinfection purposes comes from these points so that the robot can disinfect and the chance of respiratory diseases reduced globally.

Project Objectives

The primary objective of our project is to design an automatic robot that can disinfect enclosed spaces such as hospital rooms, limited access areas, etc. The robot will be capable of moving from one place to another and sensing the environment so that it can disinfect without collapsing. Some amount of computer vision will also be needed so that it will be able to protect itself from short circuits.

Project Implementation Method

A rectangular metallic robotic body. The locomotion of the robot is dependent upon a couple of motors. Their configuration with four wheels is such that rotation and translation are not a problem. The technique used for movement is a differential drive. Environmental sensing is for the avoidance of collisions. This is done with the help of pairs of ultrasonic sensors on each side of the robotic body. A microcontroller controls the inputs of the motor and sensors. An algorithm stored in the microcontroller governs the movement and sense of the robot. The camera is connected with a microcontroller for vision only for specific objects. For making sure it does the task assigned to it, A DC pump along with an automizer helps the robot in disinfection.

Benefits of the Project

If autonomous robots are used for disinfection purposes, the 3% death rate will be reduced. There will be ease for human beings in a way they do not have to go through the hassle of disinfecting. The product working method depends upon one on and off switch. Turned On, it starts to disinfect. Turned Off, it stops. The product will contribute to bringing autonomy to the world which is a rapidly growing field.

Technical Details of Final Deliverable

The final product will be hardware capable of disinfecting enclosed spaces. The robot consists of two portions. The lower portion is a base portion. It includes two motors and four wheels. There is an upper portion. It consists of eight sensors, a microcontroller, a Power source, and circuitry. On the upper portion, a DC pump, and automizer placed along with a water tank for disinfection. A tank holds 0.5 liters of solution. The Upper body is removable. Also, the tank and power source are removable. There is a camera on the front side for detection which is connected to the microcontroller. A power source can be removed for charging and a tank for refilling. No device in a robot except gear motors uses more than 12V.  The final build will achieve good disinfection of enclosed spaces for a limited area. The success of the product can be measured by monitoring its working inside enclosed spaces.
