Distance between the sensor and the color wheel of the previous robot
When we increase the distance between the color wheel of the previous robot and the color sensor of the next robot we would brake the telephone line. Communication will stop. We can not reliably detect the color when the distance is larger
Colors are influence by the lighting in the room
During recording of the tutorial the robots were behaving in different way than during classes. Main reason is that the lighting is different in both cases. Have this in mind if the telephone line is not successfully working.
