I agree with Skip, notably conditions will be different and mechanical shielding helps. I’d just add that what worked for my team last year (I never used a formal calibration routine with my 4th and 5th graders):
You probably can take a quick reading over black and white on a competition table [port view of on the brick] on the morning of the competition. If your tournament doesn't allow you access to the table you can use some time in your practice round and then make necessary changes to set-points in the programs for the later rounds.
Also probably obvious but my team found this year that is better to look for white than black given the dark background of most of the mat. [Alas] they have given up on light sensor (and gyro) because they find odometry "better" this year.
Yes, you should absolutely expect the lighting conditions to be different on each table you play on. Take that from experience! Now, that doesn't mean it WILL be different--just that you should EXPECT it to be different. That includes practice tables being different from the competition tables and different from your tables at home/school. There are different strategies for dealing with the variances, including mechanical (shielding), calibrations, and strategies that avoid relying on the sensor.
Experts ... We are using light sensor in our model... We are testing under the normal household "White Day Light" lights to sense the white color on the poster.....Will there be any color variation on the competition ....meaning how to tackle the Reflected Light Intensity variation from household light to the competition place lights. Any suggestion is appreciated.
