Abstract/Summary

This study aims to provide complementary assistance to the present surveillance system in a condominium environment. The group used a Wall following Algorithm, Docking Algorithm and an IP camera for the movement, recharging and monitoring functions respectively. With the integration of the aforementioned features, viewable range camera can now be covered. Hence, lessening some disadvantage pose by the present surveillance system.

The study is composed of three main modules: (1) Wall Following (2) Docking and charging, (3) Door Evasion and (4) implementation of the IP camera. For the wall following module, two ultrasonic sensors are installed for the detection of the presence of the wall. As long as the ultrasonic sensor detects something on its path, such as walls, furniture, appliance etc., it will just follow the contour of the obstacle and continue treading around a certain environment.

In terms of docking and charging, 30% of the total capacity of the battery is designated to be a low battery state. At the point where the robot reaches lo battery state, it will now continue to patrol until it detects the charging station. When the charging station has been detected, the robot will dock itself and charge until the battery level is full.

In terms of door evasion, the mechanism is consisted of a Hall Effect sensor and neodymium magnets. Basically, neodymium magnets are mounted in the line of path of the robot near from the opening of doors. In the case where the hall-effect sensors detected the neodymium magnets, the robot will just go straight ahead until the ultrasonic sensors detect a presence of an obstacle.

Lastly, the implementation of the camera is composed of a camera, laptop or computer and a router. The router acts as connection between the computer and the camera in which it sends the record footages to the computer. The footages can be viewed live of saved for future references.
