Me RGB Line Follower V1
Makeblock Me RGB Line Follower V1
The RGB Line Follower module is designed for line patrol competitions. It contains 4 RGB fill lights and 4 photosensitive receiving tubes. The module has a learning button and an LED indicator on the front. The learning button is used to learn the background color and the track color of the arena. There are 6 fixable screws through holes at the installation position and a RJ25 base is at the tail. The module can be applied to dark background with light-colored tracks, or light-colored background with dark tracks. The RGB Line follower needs to learn the arena through the learning button, so that it can adapt to external environments of different heights, light and other factors. The module port is marked with a blue and white label, which indicates dual-digital and I2C port that needs to be connected to the port with a blue-white mark on the main board.
Properties of Me RGB line follower V1
The RGB Line Follower contains 4 LED indicators for line following feedback and learning of new surroundings;
Learning button: recognize and record the color of the background and lane;
Supplement light: the RGB line follower supports three types of color: red, green and blue.
By switching between these colors to find the best one, the line follower can learn the arena more easily.
By pressing and holding the learning button, we can switch between these colors;
Adaptability of sensitivity;
Detection of the height:
According to the material of the arena and lighting condition, we recommend to put the sensor at 5mm – 15mm high.
The learning process of RGB line follower:
The RGB Line Follower needs to use RGB2 and RGB3 to determine the direction. If it does not learn the return values of the tracks and the background colors on the line following map
RGB Line Follower Learning Method is as follows:
- Adjusting the color of fill light: Long pressing the button to select the color of the fill light that is suitable for the current environment.
- Learning background color: Installing the RGB Line Follower module at the place to use it, so that all the 4 RGB lights directly face the background of the arena.
- Click the button, when the four indicators start to flash slowly, it indicates correct operation.
- After waiting for 2 to 3 seconds, the indicators stop flashing, it indicates the completion of background color learning.
- Learning track color: Installing the RGB Line Follower module at the place use it, so that all the 4 RGB lights directly face the track.
- Double-click the button, when the four indicators start to flash quickly, it indicates correct operation.
- After waiting for 2 to 3 seconds, the indicators stop flashing, it indicates the completion of track learning.
- Test Confirmation: Use the four probes to confirm that RGB Line Follower can correctly detect the color of background and track.
- When the background is detected, the LED corresponding to the probe turns on, and the corresponding LED turns off when the track is detected
- Re-learning: Should any change in the arena, environment, RGB Line Follower installation location, etc., it is recommended to learn them again.
