Automated chess is an emerging challenge from the field of robotics to human interaction. Customarily, chess playing robots use video camera for detecting the state of the board and robotic arm to manipulate the pieces, which makes it either expensive or too fragile to move. In this study, an automated chess board called “Chessbot” was built by combining a multitude of technologies and techniques such as voice command recognition, x and y plotting and recognition of chess pieces in a Cartesian plane, artificial intelligence algorithm, and Android mobile application. To properly execute chess moves either from a human player or computer via voice commands or a mobile game interface, the microcontroller provides motors the current and landing squares of chess pieces on the board. For the evaluation, several matches were simulated to perform various testing procedures such as voice command recognition, move log accuracy, display and user input acceptance accuracy, self-arrangement, and chess move reliability. Upon testing, Chessbot performs all the necessary tasks efficiently and accurately, which indicates the possibility of using this automated device for chess games at a hobbylevel or professional matches.

VIP-Guide: Development of Pedestrian Crossing Guide for the Visually Impaired people aims to help in the difficulties encountered in walking alone of the visually impaired persons on the streets, in crossing pedestrian lanes and identification of obstacles that might be in front of them. With the system, it will be able to aid them in terms of the different notifications provided by the system. Location from GPS module, Sound and vibration that alerts them whenever there is an obstacle detected. Upon crossing the street, a counter which is synchronized with the system counting on when to cross the street safely was also provided. Visually impaired persons will no longer need a companion whenever they will go outside. The VIP-Guide will be their companion that will surely make them safe even if they are alone and in the outdoors. A cane was also part of the system which will help them on the notification if an obstacle is near. It has a button that would allow the user to press it when an emergency takes place, will send its location through SMS, such feature will then be an aid for them to ask for help. A part of the system allows the user to connect an earphone to be able to hear notifications from the system, such as, “stop and go”, “do not cross” and a sound of the counter which is synchronized to the system’s counter on the traffic light. This feature will surely aid and guide visually impaired persons in their daily activities outside of their homes.

The value of money can be quickly grasped by the fact that virtually all economic, social, and other tasks are carried out and done using money. With dramatic shifts in global growth and other total human needs, the value of money is rising day after day. Money is an important asset that will allow you to run your life. The exchange of goods for products is an older custom, and you cannot buy something you want without any money. It's straightforward to use money, you just have to glance at the currency instantly, pull the appropriate sum of cash out, and that's it. But that may become a challenging job for those who cannot see. Among the most significant issues facing visually impaired people is the identification of money, particularly for paper currency. In this study, it focuses on this problem and is based on a machine vision technique called object detection. The study used Raspberry Pi 4 as a microcontroller, Pi Camera as its capturing device, and a speaker for audio in announcing the detected bill. EyeBill-PH has been done with an overall testing accuracy of 86.3%.

Liquefied Petroleum Gas (LPG) is readily available to consumers around the world because LPG is a clean, portable, and efficient source of energy. LPG is currently used by hundreds of millions of people in the world and there are more than 1000 applications. LPG cylinder may leak as a liquid or a gas. If the source of ignition and gas meets LPG can explode or burn. LPG can make the lives of the people in the house endangered and can cause cold burns to the skin. To ensure the safety and security of the consumers using LPG the study aims to develop a device that can detect gas, smoke, and flame from the LPG cylinder and can notify the owner via text messages applying a rule-based approach. The system can display also a warning message and can alarm the owner using a buzzer. The researchers conducted functionality testing with twenty (20) trials in checking the accuracy of the system were obtained a 100% accuracy. This proves that the system is reliable and efficient when using at home by the consumers.
