Abstract: The primary concern of every household when they leave their home is safety of the home as well as its protection. This study deals with creating a solution for such a situation in the form of a small robot that can take care of the security in the home. The system uses several sensors that are mounted on it as well as in the home so that it can detect any breach in security or any abnormal situation in the household and inform the owners immediately as well as raise an alarm so that those nearby can take effective actions. The system can be used in cost efficient manner and can handle multiple operations. The main feature of the system is when it detects obstacles it avoids the obstacle after avoiding the obstacle it again finds the black line path and returns to the original path. The robot uses an ATMega2560 as its microcontroller since it provides higher transmission rate and higher clock speed with more memory in terms of RAM and Flash. This enables the system to respond faster when compared to using other microcontrollers.
