We can't get the most of the robot and its sensors. Others teams are following the lines faster than us. What can we do?
Basics for Line following with one and two Light/Color Sensors
First, learn to use the light sensor. After that, there are basic algorithms for the sensors, like bump, 3 states, 5 states
More advanced topics for faster following of lines
Calibration is very important. Then you can implement PLF(Proportional Line Following). You can also use a state machine is the line has gaps
