This project involved designing and developing an autonomous robot capable of line-following behavior, enhanced with the ability to recognize and respond appropriately to traffic signals. The robot was programmed to pause its movement when detecting a red traffic signal and resume afterward, demonstrating practical functionality applicable to real-world scenarios.
Line Following: The robot effectively tracks and follows a predefined line using sensors to navigate smoothly and accurately.
Traffic Signal Detection: Utilizing sensor data, the robot identifies a red traffic signal positioned on its right side, stopping for exactly five seconds before resuming movement.
An additional feature includes the robot flashing indicator lights to communicate clearly when it has detected the red traffic signal.
The robot utilizes sensor arrays for precise line tracking and employs color detection sensors specifically calibrated for recognizing red traffic signals. Control logic was implemented to process sensor input and manage the robot's motors, stopping the robot for precisely 5 seconds upon detection of the red signal.
This implementation can be adapted for automated guided vehicles (AGVs) in industrial environments, educational robotics for teaching autonomous navigation concepts, and even scaled implementations for smart city transportation systems.
Testing confirmed the robot accurately detected the red traffic signal, consistently stopping for the mandated five seconds, and reliably following the designated path. Moreover, the flashing indicator provided clear visual feedback confirming successful signal detection.
Through this project, key insights were gained regarding sensor integration, real-time data processing, and implementing efficient and reliable robotic behaviors in response to environmental signals.
Future project improvements could include expanding recognition capabilities to other signal colors (yellow and green), integrating more complex navigation paths, and optimizing energy management for extended operational periods.
This line-following robot demonstrates significant practical applications, showcasing effective integration of basic autonomous navigation principles and real-time signal processing for responsive robotic behavior.
