The project aims in designing a robot which is c controlling using Android mobile phone through Bluetooth. It switches on the UV lamp through which UV rays are emitted and also sanitize the surroundings. Ultraviolet-C Radiation, Disinfection, and Corona virus given the current outbreak of Corona virus Disease. Since there is no vaccine yet available in the market, the only way to be safe is by taking precautions. It is suggested to sanitize surroundings that help in slowing down the spread of infection as the virus mainly gets transmitted with the aerosols which come out of an infected person's nose or mouth while coughing or sneezing. To solve these problems, we have designed a microcontroller-based sanitization robot along with UV lamp. The project mainly designs a robot that can be operated using Android mobile phone. The controlling of the Robot is done wirelessly through Android smart phone using the Bluetooth feature present in it. This system also uses, sanitizer, UV lamp along with relay driver and two DC motor along with l293d motor driver with Robot chassis to build this Robotic car setup. The system also controls the sanitizer and UV lamp using android mobile. Here relay likes as a switch to on and off the sanitizer and UV lamp. The controlling device of the whole system is a Microcontroller. Bluetooth module, DC motors are interfaced to the Microcontroller. The data received by the Bluetooth module from Android smart phone is fed as input to the controller. The controller acts accordingly on the DC motors of the Robot. In achieving the task, the controller is loaded with a program written using Embedded ‘C’ language.        

The objectives of the project include:  

1. To design and develop a wireless sanitizing robot controlled through a mobile phone.
2. To use an Android smartphone with a touch screen for robot control.
3. To establish Bluetooth wireless communication between the mobile phone and robot.
4. To develop a robot that can sanitize surrounding areas.
5. To use a UV lamp for reducing microorganisms and viruses on exposed surfaces.
