Thanks for pointing it out. You are absolutely correct, the LEDs can be turned off with a knob and there is no need for a special LED-covering part.

We have tested our robot in very poor lighting conditions but with the LEDs fully on, and color recognition worked OK. However we have received photographs from other users where flashes make color recognition extremely difficult. Our recommendation in this case is to switch the LEDs off and use brighter ambient light.
