    Automated Farming Robot
    (Uva Wellassa University of Sri Lanka, 2021) Fazil, N.M.; Hiroshaan, V.
    Robotics is a fascinating field of engineering that provides many opportunities for research. In addition, the evolution of technology in recent years has led to intelligent mobile robots. As farms grow in size, together with the size of the equipment used on them, there is a need for ways to automate processes, previously performed by the farmer himself, such as handling the equipments himself to perform the task. The control of these robots, however, is a difficult task that involves knowledge in different areas such as robotics, automation, programming, electronics, etc. The objective of this research is to technically develop the new agricultural technologies to savings in terms of both cost and time, to optimize production efficiency, declining availability of manpower, minimize production-associated risks. Hence automation is the ideal solution to overcome all the shortcomings by creating machines that perform the operations and automating it to increase yield on a large scale. In this the robots are developed to concentrate in an efficient manner and also it is expected to perform the operations autonomously such as Drilling (for plantations of seeds), seed dispensing and watering. For manual control the robot uses the Bluetooth pairing app as control device and helps in the navigation of the robot outside the field Keywords: Farming Robot; Bluetooth module; Arduino;Agriculture; Water pump

    Autonomous Baby Care System
    (Uva Wellassa University of Sri Lanka, 2018) Pushpakanthan, B.; Hiroshaan, V.
    Baby nets are important for protecting babies from mosquitoes and insects, and give a good sleeping experience. Baby cradles, which are currently available in the market do not give any extra level protection to babies. Existing systems do not have the interaction with mothers as they cannot be with their babies all the time. Therefore, in order to ensure a baby's safety in all aspects, the main objective of this study is to produce an Autonomous Baby Care System to provide an extra level of protection to babies with alert message system. In some cases, if a mother is not in the close proximity to her baby and the baby is awakened from sleep and crying, the situation can be identified using sound sensors and then the system will sing a lullaby and swing the baby cradle to make the baby sleep. And also if the baby has urinated, it can be identified using humidity sensor and alert the mother with a buzzer sound along with the LCD display message to change the diapers. In addition, the system will continuously monitor the weather around the baby and according to the temperature, it will control the fan speed. Arduino is the main control unit of this system. Arduino gets the input signals from the sensors attached to the baby net, process it, and gives output signals to take necessary actions, such as controlling the fan, playing a lullaby, and swinging the cradle. Also it will send the status to mother's receiver panel. The system successfully identifies the input signals from Sound sensor, Temperature sensor and Humidity sensor and results desired actions from 94% of the outputs. As a future improvement and for commercial use, Artificial Intelligent (Al) techniques can be used to improve the accuracy of the output of the sensors.

    Electronic Bus Ticket System
    (Uva Wellassa University of Sri Lanka, 2019) Fazil, N.M.; Hiroshaan, V.
    In Sri Lanka transportation is mainly based on road network. Buses are the principal mode of public transport. Bus service is provided by the Sri Lanka Transport Board (SLTB) and privately owned buses. Main objective of the project is to make passengers journey comfortable, facilitate conductor and drivers work easy and eliminate the cheating done by passenger by automating the ticket system. It also helps driver to easily identify the bus stops where he needs to drop the passenger and how many passengers. Therefore, he can drive smoothly. System contains conductor display unit and driver display unit. Both units connected by the Bluetooth module (HC-05). In conductor module, conductor prints a ticket to a passenger by keypad and send the bus stop detail to the Arduino, then the Arduino transfer signal to Bluetooth module. Finally, Bluetooth module receive the command and it send to the next Bluetooth module of the driver unit. Then driver unit receive the signal and it display how many passengers to drop on each stop, on its display. Then cheating also will be reduced. Driver know in advance where to stop the bus. Passengers no need to ring the bell to inform the driver to stop the bus. Therefore, the journey will be smooth and comfortable for both the passenger and driver. If the system is embedded with google map, then it will be more convenient for driver. As a future implementation to make the system more efficient incorporate google map to display the bus stop.
