Hi all,
I am trying to get some middle school kids playing a bit with the robosoccer
idea. I don't want to frustrate them with the fluctuating IR ball. So, I am
planning to find a constant "lighted" ball for them instead, but no luck.
Wonder if anyone may have a suggestion.
By the way, the official IR soccer ball has a very unreliable IR emission.
there are times my IR sensor just simply did not get any feedback even when
it is right next to it. For my high school kids, I had them to implement
some kind of either probability, or just simply skip the reading if there
are spikes of drop. Therefore, for the younger ones, I'd like to find a
lighted ball. any suggestion is appreciated.

| (...) It's not ideal for stock LEGO sensors I think, but it might be good to point out to them that the reason it blinks is to make things *easier*. With a source pulsing near a known frequency, ambient conditions are much easier to cancel out. (...) (17 years ago, 29-May-07, to lugnet.robotics.edu)
