To provide Innovative Solutions to solve the COVID-19 Pandemic that has affected the entire Human Community.

About Us

We are a team of 5, having expertise in Robotics and Designing which gives us an edge to provide solutions which do not require human intervention.


Faced due to Covid-19:
This virus has led to the following problems:
Widespread infection.
Improper Technology for Sanitization of Vulnerable Areas.
Technologies available are Costly.
But a question arises here. UVC radiation is very harmful to humans, then how we will ensure correct control of this drive. Read-Along!


Provide low cost Sanitizing Robot.
Safety is ensured without any hindrance to people working around the places where the Robot will traverse.
Human Intervention is not required as the system is FULLY AUTONOMOUS. It will travel along the entire floor space emitting UVC radiation only along its way on the floor and the walls faced by the light.
Since, in this fight with COVID-19, we all have to stand strong and ensure that no lapses are entertained. This system will be deployed in hospitals and commercial spaces where the chances of virus spreading are higher.

Implementation Plan

It is a four-wheel mecanum drive which will be used to disinfect the Hospital Area and Commercial Space. It is fully autonomous using UVC Tubes. The UVC tubes are placed at positions which ensures efficient sanitization.
The Drive consists of Microcontroller (Arduino) which controls the motor driver and is being powered by the power distribution board. Motor Driver is used to driving the four wheels with the help of motors. The sensor data we get as input is fused with each other using an autonomous exploration algorithm which helps us get a 3D mapped image of the surroundings. This image gives us the accurate distance and angle of an obstacle/object from the robot as output so that it can avoid it easily. As there are multiple sensors the field of view is wide and the results are more accurate.

Impact of the Project

Why are we using Ultraviolet Light?
Ultraviolet light can be an effective measure for decontaminating surfaces that may be contaminated by the SARS-CoV-2 virus by inducing photodimers in the genomes of microorganisms.

Is it Effective against SARS-CoV-2?
It is estimated that the SARS-CoV-2 virus can survive on surfaces for up to 9 days, based on its similarity to SARS and MERS. Therefore, different research shows that the average dose required to disinfect the virus and bacteria is 67 J/m^2.


The UV doses required to disinfect the coronavirus is 67 joule/m^2, which is an average value get from research papers.

If we are using a UVC tube of 15 watts, so to disinfect the viruses with an efficiency of almost 99% just we need to calculate is the time of exposure for which the surface needs to be exposed on UV radiation.
To find the time of exposure we can use ‘’INVERSE SQUARE LAW’’ of radiation which is given by,
WHERE, E/A=D= UV doses required to disinfect viruses in joule/m2
A= Area of exposure
T= Time of exposure
R= distance between light source and surface
So,T=D*A/P = (D*2piR2)/P
T = (67*2*pi*0.5*0.5)/15 = 7.01
Here we used half surface area of the sphere(2piR2) as the luminous flux in our bot has been concentrated within half of the spherical curvature in fact less than that.
With these calculations, it is cleared that within 7 sec. of exposure of UV radiation from a distance of 0.5m we can have almost 99% of the virus-free surface.

Note- UVC-emitting unit varies depending on the distance between the light source and the irradiation area and any object in between that shadows.

Work done During Weekend

1)CAD Designing.
2)The calculation for Using UVC light and its Intensity. (Time Required for Disinfection)
3)Simulation in WeBots.
4)A Simple Prototype design using hands-on material present with us in our Lab.
5)Completion of Programming and Control Algorithm.

Requirements for Continuing the Project

It is important to continue working on this project, in order to achieve the best results. The following points explain the requirements for continuing this project:
1)The need to ensure that there is not an upsurge of cases, timely sanitization of public places are required.
2)Therefore we need to use this project to ensure that public health is maintained.
3)The maximum cost for making this robot is 16,000 INR. This could easily be reduced if the robot is in mass production.
4)The components required (as mentioned in Bill of Materials) are readily available and easy to interface.
On average, only 4 members are required to make this robot in a week, which helps in employing people and further reduces the problem of Unemployment.

Value of the Project after Crisis

The need for the projects that provide solutions to COVID-19 virus is that it should be implemented even after the effects have slowed down. As per reports, scientists predict that humans have to practise some form of social distancing till 2022. Therefore to ensure that our environment is clean, we need to deploy such projects which help in the long run.
The following points explain the value of this project after the crisis:
1)The robot can be deployed in public places since it is fully autonomous to disinfect the area.
2)Sanitization will prevent the growth of virus and bacteria, therefore this robot can ensure timely and successful operation in killing the virus.
3)The making of the robot will generate employment that will contribute to the already crippled world economy.

Business Model

Core Value: To provide the best sanitizing robot that ensures the disinfecting of workplaces and help in continuing a better life.
Target Customers: Primarily Hospitals and Commercial Workspaces like offices, colleges, schools, etc where there is a high probability of spread of the virus.
Revenue Streams: With the help of this product the customers will ensure timely sanitization of there workspaces and the cost earned from selling these will be used to fight this virus in upcoming years. 35% of the profit earned from this will be donated to families of medical professionals, which lost their loved ones in this fight.

What Makes Us Stand Out

The current pandemic termed as Coronavirus has brought the entire humanity to its knees. To provide the frontline warriors appropriate ammunition to fight against this virus, should be our only motto. At this time of emergency, we would like to propose a PYRO- Sanitizing Robot. The Robot is fully autonomous which helps in traversing the area and cleaning it. The sanitization is carried out using UV-C tubes which has the capability to destroy the virus. The robot will be deployed in areas which are vulnerable and has the potential to become virus hotspots like hospitals, schools, colleges, etc.
To ensure proper dosage is emitted by UV-C unit, the distance is calculated and proper consideration has been given to shadowed and/or critical areas. Disposable Indicators is used which helps us to ensure that an adequate dose has been given.
