“3D TRACKING CAPACITANCE BASED ROS CONTROLLED ROBOT ARM”
Abstract— This paper presents a design procedure of 3d tracking capacitance-based ROS controlled robot arm. A robot operating system (ROS) was modeled to control the robotic arm with 4 degrees of freedom (DOF) to imitate the virtual (Simulation) to reality. ROS is middleware upon which the system can be developed or constructed. The basic controlling operation can be categorized into two sections. The initial process begins with RVIZ simulator control and then control by 3D Cartesian coordinates given by ROS commands to control the arm. The arm covers a quarter of with a radius of 31 cm approximately. Capacitive based 3D tracking mechanism was used to control the robotic arm and update the Simulator by detecting hand gestures. The hand was limited with-in 12 cm cubic .

” DEEP CONVOLUTION NEURAL NETWORK (CNN) USING A MONOCULAR CAMERA AND A 2D LIDAR FOR ROBUST QUADROTOR OBSTACLE AVOIDANCE “
Abstract— Quadrotor platforms have become a vital tool in the industry as it is being used as the primary go to technology approach across many sectors including law-enforcement, survey, photography, videography, inspection and etc. However, most users in these industries are not trained or certified pilots, hence introducing safety cautions of crashing drones generated by piloting errors in urban environments causing damage to property and human lives. One of the ways to mitigate such crashes is by introducing robust obstacle avoidance capabilities to the drones in manual control mode. We propose a robust combination technique approach for obstacle avoidance on a

IMPLEMENTATION OF A ROBUST GROUND-STATION FOR LOW EARTH ORBIT (LEO) SATELLITE COMMUNICATION
Abstract—The Ground station developed by ACCIMT for receiving Amateur band signals utilizes a central Terminal Node Controller (TNC) based on a Gaussian Minimum Shift Keying (GMSK) modem. The TNC is responsible for modulation and demodulation of the communication data. A commercially available actuator and a controller were used for antenna pointing. A computer interface for in-house developed hardware system which is compatible with RS-232 protocol was developed. A Graphical User Interface (GUI) software application running on a standard computer acts as the satellite’s operating environment. A commercially available transceiver (ICOM 9100) was used to transmit telemetry control to the satellite and receive the satellite Continuous Wave (CW) beacon and data. In-house developed software was used for satellite tracking and antenna rotor controlling Two Line Element (TLE) file of an interesting satellite is obtained from available sources to feed into the said software. The software generates a serial data stream to the rotor controller via the protocol converter, which converts RS232 data to controller input voltages. Three open-source JavaScript (Google maps API, TLEjs and jspredict) libraries were used as Application Program Interface (APIs) to develop the said software with electron js. These APIs get the TLE as an input and output the accurate orientation data, which is then fed into the antenna rotator so that it can maintain the antenna in the direction of satellites.

PILOT RESEARCH PROJECT ON REAL-TIME MONITORING OF RIVER WATER LEVEL AND IRRIGATION MANAGEMENT AT GRAVITY OUTLETS (NILWALA RIVER)
Abstract—Flooding has become a major problem in most of the countries around the world, causing huge damages. It affects the farming community, incurring disturbance to day to day activities, mainly by damaging the farming land and infrastructure. Although there are methods to forecast rainfall or to track storm path precisely from the satellite images in the world, the need for real-time monitored data such as river water level is essential to make a reasonable decision on the actions necessary to prevent flooding in an automated manner. The rivers are usually located in the low lying lands and agriculture productions usually utilize river water in these areas. In wet zone areas due to heavy rain small streams and canals of the main river which are feeding agriculture land gets more water compared to upstream sections. In this situation, Gravity Outlets (GO) come into action where the decision is taken to transfer the water by using gravity or forced pumping, after comparing the upstream water level (riverside) and downstream water level (Yaya or protection side). This system is widely used in Europe. At present, all the pump houses are fixed with river and landside conventional manual gauges to monitor the water level and also to make decisions for pump operation. Since, this is a manual, individual dependent and less reliable system, GO operation is not efficient. It is observed by the Department of Irrigation that one-centimeter level gravity difference can save pumping costs in the order of magnitude. Last few years it has faced more disputes due to less finance allocation from the government for these routine tasks. Paddy fields of farmers and low land residential areas are severely damaged during the flood instances. Through an automated, reliable and quick data providing solution based on the Internet utilizing GPRS (General Packet Radio Switch), information can be delivered to the action points that can streamline the operation of gravity outlets. It will greatly reduce the cost of daily operation and farmer conflict for the Department of Irrigation.

AN INTELLIGENT TRAFFIC SIGN RECOGNITION SYSTEM FOR SRI LANKAN DRIVERS
Abstract—Automatic traffic sign detection and recognition system plays a crucial role in enhancing the safety of road users and of motor vehicles. It provides accurate and timely warning alerts of driving conditions to drivers with a minimal human effort. The effectiveness of such system depends on many factors such as vehicle speed, background complexity, lightning and weather conditions. In this paper, we propose an automatic traffic sign detection and recognition system suitable for Sri Lankan road system. The proposed system consists of two stages, traffic sign detection stage and traffic sign recognition stage. We adopt a Haar Cascade classifier for traffic sign detection and Convolutional Neural Network (CNN) approach for traffic sign recognition. Experimental results demonstrate the effectiveness of the proposed automatic traffic sign detection and recognition system for different vehicle driving speeds

A Regulatory framework for a Smart Hydroponics System
Abstract—Climate change is instigating extreme weather events, which include heat waves, droughts, strong winds and heavy rainfall, and these events can impact the availability of water for agriculture. The unpredictable droughts and floods in Sri Lanka have made the production of food crops difficult. Excess water and decreased soil moisture have resulted in a sharp decrease in crop yield. Thus, there has emerged an urgent need to employ new agricultural technics that use less water and nutrients, and which are not easily affected by external environmental variables. Aeroponics is fast becoming an opposite solution to the aforementioned challenges posed by climate change to agriculture. Furthermore, this method of growing crops can be used to grow crops in the space and other planets. However, the technic of growing plants using aeroponics is mechanically convoluted, is vulnerable to malfunction and requires accurate regulation and control of water and nutrients. Ergo, the focus of this research is on constructing an automated system that regulates and monitors the aeroponic system to reduce to a greater extent the challenges this agricultural technic faces in becoming a commercially viable solution to the modern agricultural problems. This will be accomplished by the use of ultrasonic atomizers, pH and EC regulators, gas sensors, temperature regulators, humidity regulators, and a single-board computer, while a mobile app and a web interface will be employed to allow the user to monitor and interact with the system. The user will also be warned in case a malfunction takes place in order to control the amount of damage to the plant.
