Everyone,
I wasn’t trying to imply that it was
the other team deliberately trying to mess us up. It was just
a parent trying to document their own team’s robot without realizing that
they might impact our robot inadvertently with the flash.

Phography and Light Sensors
Our team has almost indisputable evidence
from last year’s state tournament of a parent from a team on the adjacent
table taking rapid shots with the flash going off multiple times a second
having an impact on our robot. As our robot came to spot where it needed
to find a black line and respond, the sensor reading it got must have looked to
light and it kept going well past where the black line was, even though the
sensor went right across the line without noticing it. Our sensor was
shielded pretty well from the front, but it wasn’t possible to shield the
side of the sensor well and this is the angle our robot was in with respect to
the camera when it went astray and never found the line it was hunting for.
We were all surprised at the failure (which caused us to lose about 50
points) and it wasn’t until we were watching the footage later that night
that we noticed the continuous flash photography next to our table and pointing
right at our robot. So coaches, please have your parents abide by rule of
no flash photography during matches.

Has
anyone experienced flash photography interfering with light sensors during a
mission run? Our team was asking this questions and I do not have
an answer.
