Figure 3-12 White Tawara vs. Black Sumo Ring Surface
Example Program - TestFrontQtiLineSensors.bs2
Keep well away from direct sunlight and other sources of bright light. Your SumoBot
and SumoBot Robot Competition Ring poster should be well away from any sources of
direct sunlight and other bright lights. Close nearby blinds if necessary, and make sure the
light sources in your work area are either fluorescent or indirect incandescent.
√ Enter, save, and run TestFrontQtiLineSensors.bs2.
√ Test both QTI sensors light and dark surfaces.
√ Test both QTI sensors on the Sumo Ring poster in the black area, the white
tawara border, and the dark gray shikiri lines.
√ Make notes of all the QTI measurements.
√ Try it in a brightly lit room.
√ Try it in a dimly lit room and compare the difference.
√ Try a variety of black and white surfaces and consider what value you think
would be best for your programs to decide whether a QTI is over a black or
white surface.
