ABSTRACT
Problem: Many people are worried regarding the safety of their home/ office when they are away.
Solution: We have developed a small mobile robot that can guard the home when the owner is away from home. The robot has several on board sensors to detect home safety. Whenever it detects breach of safety, it sounds an alarm to draw the attention of the neighbors.
Implementation: The robot has a fire senor to detect fire, detects window break using piezo sensor element, also detects Door break using wire break sensor. A buzzer based alarm is triggered when the situation is abnormal. The robot keeps moving in the room when it is activated. It has bump sensor to detect wall in front of it.
The project is equipped to display various parameters using Liquid crystal display. The display consumes low power and operates with battery power also.
This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac out put of secondary of 230/12V step down transformer.
Advantages:
- Low cost implementation, Improves house safety, Digital indication of sensors,
- Reliable sensors, Small size, Low Power consumption
Scopes for Advancements:
- Remote control the robot from any where in the world
- Cell mounted on the robot can provide visual information also
Target customers/Applications:
Homes, Offices, Shops, Military, go downs, Farm house etc
