Our team, Dream Epic, actively participated in the SLRC 2021 competitions, engaging in two distinct stages. The first stage comprised both a Virtual Round and a Physical Round. The Virtual Round unfolded in the Webots simulation platform, involving tasks such as color detection, white line following, and pillar distance detection. While our robot adeptly identified floor colors, followed white lines, and navigated around walls, it faced challenges in crossing the final white line to reach the ultimate floor color. Despite this obstacle, we secured partial completion points in the virtual stage. In the subsequent Physical Round of the first stage, our team successfully executed tasks such as white square detection, color detection, pillar distance measurement, IR sensor panel utilization, and a precise 90-degree turn. These accomplishments earned us significant points, leading to Dream Epic securing a commendable fourth place among the competitors in the first stage.
The second stage of the SLRC competition was entirely conducted in the virtual realm using the Webots software. The final round tasks encompassed line following, box detection, operating an arm capable of moving and carrying boxes, detecting the color of the boxes, and facilitating communication between two robots. While our team excelled in certain tasks, the time constraints prevented us from completing all objectives within the allocated timeline. Consequently, we were eliminated in the final round, with only the top three teams advancing to the ultimate competition.
In the initial stage, specifically the virtual round, I was responsible for tasks such as line following and other related activities. During the physical round, my focus shifted to executing the color detection task utilizing the TCS34725 color sensor. I am pleased to report that my contribution in this phase was successful, and our team received full marks for the accomplished task.
Moving on to the second stage, which was entirely conducted in the virtual domain, my involvement began with the creation of a sample arena using SolidWorks designs. Additionally, I handled tasks such as line following and executing 90-degree turns utilizing the PID controller mechanism. Moreover, I played a crucial role in implementing robot communications using C++ language within the Webots environment.
My name is Sugendran Luxshan, and I'm from Jaffna, Sri Lanka. Currently, I'm an undergraduate student studying Electronic & Telecommunication Engineering at the University of Moratuwa. I attended Jaffna Hindu College from 2010 to 2018. In 2015, I achieved notable results in my G.C.E O/Level with 7As and 2Bs. Moving on to the G.C.E A/Level in 2018, a nationwide competitive exam, I secured 3As in the physical science stream with a Z-Score of 2.1166. I have bilingual proficiency in English, native proficiency in Tamil, and limited working proficiency in Sinhala. My basic skills include Python and Java programming, Adobe Photoshop, Microsoft Office, Arduino Environment, and MATLAB. During my school days, I actively participated in extracurricular activities such as playing cricket on the school team, being a member of the Science & Math Union, and holding the position of Vice President in the Young Men Hindu Association. In university, I'm a member of the Tamil L...
RGB Color Sensor Abstract The Coloris RGB colour sensor is a versatile device designed to detect the colour of any given surface. It incorporates a unique feature allowing users to illuminate a surface with a specified colour using RGB LED by providing custom red (R), green (G), and blue (B) values. The core concept of the project is based on the principle that coloured objects reflect their specific colour and absorb others. The device achieves colour detection by illuminating a surface and analyzing the reflected colour light. The Coloris sensor is built around an ATMega microcontroller, utilizing multiple Light-Dependent Resistors (LDRs) for accurate colour sensing. Upon receiving input from an unknown coloured surface, the Coloris sensor outputs results in the RGB colour model format, highlighting the dominating colour among red, green, and blue. Additionally, the device provides a visual representation of the RGB colour mixture using a single RGB LED and a 16*2 LCD Displa...
