This project focused on develops and modify a remotely operated Quadcopter system with a first person view camera. These Quadcopter is controlled through a 2.5 GHz remote control system. Communication between remote controller and Quadcopter is done by using wireless communication system. The balancing system of the Quadcopter is controlled by a gyro sensor attached with the main board. For a damage less landing and a smooth takeoff the quadcopter has a 12 cm long landing gears. The camera has been attached under the quadcopter for a better view and it uses Wi-Fi communication method to stream the video to the laptop. The main also contains a GPS module and a light sensor which can help to locate the quadcopter in case of any lost and the light sensor is attached if the quadcopter enter dark zone so the pilot can spot the quadcopter with the automatic light. Output from Arduino Uno board used to control quadcopter propellers the sensors and the communication. The output sensor data is been monitored by a GUI (Android application) and the communication between the sensors and the application made using Bluetooth module.
Blindness is an area of inadequate the visual conception because of physiological or even neurological aspects. The partial blindness corresponds to the insufficient integration in the expansion of the optic confidence or perhaps visual center of the eye, and also over-all total blindness is the complete inadequacy of the visual light perception. Within this research, a basic, inexpensive, friendly user, sensible blind assist technique is developed to be integrated with the portability of both blind and even visually impaired people in a particular region. The presented work consists of a wearable apparatus is made up of the head hat to facilitate the blind particular person to get around single-handedly safely and securely in order to keep away from any kind of obstructions that could be experienced, even if mounted and also mobile phone, to avoid virtually any probable accident. The primary function of this product is the Ultrasonic sensing unit which is able to inform the blind people if there exist any specific obstacles or otherwise not around them along with the vibrating motor probably would informs the blind people who which negative are the obstacles located. In addition, by pressing the home or work button this system will straight away link to MIT app inventor and the app will send a signal to Google maps to guide the blind people to its desired location. The implemented system is fast, and easy to use and an innovative affordable solution to blind and visually impaired people in third world countries.
