Robot Specifications:
Robots must be equipped with AI cameras and line sensors.
Dimensions of the robot should not exceed 25 x 25 cm.
Robots must be powered by batteries only.
Track Navigation:
Robots must follow the black on a white background track outlined on the game field.
Time Limits:
Each participants is given a maximum of 1 and a half minutes to complete the course.
Within 1 and a half minutes, participants are allowed to restart the robot if they want, However, time will still be continued and 5 marks will be deduct for every restart.
If the self driving car stopped on the game field, marks will be given upon the reached flag.
The participants with the highest marks scored throughout the competition wins.
Marks Given for:
Fastest Completion: Awarded to the participants with the fastest completion time.
Best Navigation: Awarded to the participants with the highest accuracy and smooth navigation points.
Infrared (IR) sensors or photodiodes that detect the difference in light intensity between the line and the background.
Analog or digital output that indicates the sensor’s readings.
E6 Controller that processes the sensor data and drives the motors accordingly.
The Intelligent Module sensor are placed close to the ground and continuously monitor the surface below.
Black line on White background: The black line absorbs more infrared light, causing the sensor to detect a lower reflection (darker signal). The white background reflects more infrared light, causing a higher signal.
White line on Black background: In this case, the white line reflects more infrared light (higher signal), while the black background absorbs the light (lower signal).
The basic principle behind line-following robots is to keep the robot centered on the line, adjusting its movements based on the feedback from the sensors.
When a sensor detects a line, the E6 controller can adjust the direction of the robot by controlling the motors.
If Sensor #1 detects a junction, the robot will turn left.
If Sensor #7 detects a junction, the robot will turn right.
If both Sensor #1 and Sensor #7 detect junctions, the robot will stop.
