Advanced coloured lines following robot I am trying to build a coloured lines following robot, and I would like to know what kind of sensors do I use for my robot to differentiate and detect several different coloured lines?
If you are using the EV3 Sensors you should use the EV3 Color Sensor which can detect 8 colors (colorless, black, blue, green, yellow, red, white and brown). If you are using the NXT I would recommend the HiTechnic Color Sensor or HiTechnic Color Sensor V2... I hope I could help.
