The calibration issue is this... you want your light sensor to give you a reading of 0 for black and 100 for white but under varying conditions, you might get some other range - say 23 to 84. By calibrating the sensor you can get it back to 0-100 under your current conditions. Remember of course that these are inexact measurements which is why the sensor blocks have you look for "greater than" or "less than" values.

Using sensor calibration you can adjust your robot to handle different environmental conditions without changing your programs at all.

For more info, instructions on how to use the standard calibration program and other optional programs, try this page.

My team is using light sensor- they have been taking the average of white and black readings and imputing that theshold into their program. How can they callibrate at the tournament when they can't have a computer at the table to adjust the threshold if necessary?

Thanks

You should bring four copies to the tournament - one for registration and one for each of the judging panels.

It had a list of every member of our team and answered four questions about our overall experience. Are we doing that list this year? If so, where might I find the form as a pdf or jpg? Please forgive me if this has already been answered.
