A study conducted by Araganos, Dejarme, Hari, and Quesea (2010) on “Prototype Design of a Wi-Fi Controlled Surveillance Rover” deals with the prototype design of Wi-Fi controlled surveillance rover, and the rover acts a personal computer controlling motors through the parallel ports. Windows xp operating system was installed in the pc rover which receives commands from a laptop linked through an 802.11b/g router and the use of remote desktop program such as Ultra Virtual Network Computing (UltraVNC). It uses relays and a visual basic program for forward, backward and steering left and right. The main conditions of the rover are the system unit, motor, camera, wireless adapter, power supply and the program.
Aracan, Cada, Roasa, and Villanueva (2009) on “Prototype of the Solar Powered Surveillance Robot" noted that the components of the design comprises of five main areas which where the following: power supply, sensor, microprocessor, surveillance camera, and motor. Visual basic was used for the programming. This study is composed of the construction of the mechanism and software program embedded on the robot.
A research made by Bundalian (2011) entitled "A Modified Indoor Wireless Audio and Video Transmitter” expounded that the circuit is a miniaturized broadcast TV transmitter that can be used for transmitting program from a vcr or any multimedia player at a distance up to 5miters away without any physical connections, but with the proposed modification, some components need to be replaced to enchase the distance range to send the information from the source to the receiver monitor at a distance of 20miters.The study aims to design and develop an efficient wireless services connectivity to eliminate the potential hazard due to sagging of any electronics media cable to the user and to prevent farcing of any electronics media player for setting up an audio and video system. The study (1) Design and modified an indoor wireless audio video, (2) Constructed the prototype and (3) tested and evaluated the functionality of the design and the effectiveness of the wireless survey system.
A study proposed by Estarija, Libao, and Mendoza (2010) entitled “Prototype Design of an RF Controlled Mobile Surveillance Robot with Integrated Control” showed a design and executed a mobile surveillance that operated in two control systems: a handled RF controller and on integrated control. The rover is made up of a self-designed chassis, two lead acid batteries, a power inverter, and a receiver unit derived from a remote controlled toy car. The first control system is made up of an RF controller operating at 27.145 MHz and having a modified antenna to attain better range. The second control system incorporates the same RF controller and a transmitter unit but this time, the rover is being controlled by a computer via Visual Basic 6.0. The research is designed as such so that there will be least possible room for error, even though it may be subjected to future alterations.
Another design was taken from the study of from Basit, Delos Reyes, Juniosa, and Navarro (2010). The design is composed of lead-acid battery, control circuitry, bumper sensors, and servo-based under and camera for planning and surveillance system. Included in this study are the electronic circuit design adaptation and construction of the surface water surveillance robot and other additional features such as sequential LED display and sound effect indicator.
In the study entitled, “Remote Mobile Monitoring Robot” by Amano, Antonio, Balois, Barretto, and Niere (2010), they asserted that the technology is very fast expanding. Different state-of-the -art equipment are rising and slowly becoming a necessity. Robot or robotics is one of the fast rising technologies nowadays. A robot is an automatic device that performs functions normally ascribed to humans. Mobile robots are automatic machines having the capability to move around in their environment and are not fixed to one physical location. Security is one of the issues of mobile robots this generations is currently facing and monitoring is one of the solutions. It is process of routinely gathering information on all aspects of the project. The design of a remote mobile monitoring robot is simply a mobile robot equipped with monitoring camera. The main purpose of this system is to develop a more reliable and convenient security device. It is made remote controlled using wireless technology for the user to be able to control in the way they want. The researchers used wireless router and wireless LAN to make the prototype wireless. In creating a device like this, the proponents first have to gather different electronic components such as resistors, transistors, capacitors, diodes, LED, voltage regulators and relays for the power supply circuit and relay circuit as well. Relay circuit is connected to the wiper motor which will control the movement of the gears in different directions. UPS is used as the power source. This system will be usable because it is very easy to use or operate. In addition, it is efficient because it is cheaper than paying security personnel and it can prevent life threatening. The program used to operate the system is Visual Basic because it is simple and user-friendly. It is also found out that developing system like this need time and further studies for the system to be successful.
