Man, that sucks. I loved your robot, and I really wanted to see it work. hte
design was just beautiful. Maybe you can keep it together and show us all
sometime? Maybe we will do pick and place again? I, for one see lots of room
for improvement in my robot. Iain also expressed interest in having another
go. I suppose we are still just a whining minority though. I know I
mentioned this to you at the competition, Derek, but for the others: there
is an easy way to get reliable readings from the light sensors. Just buy a
Lego light, and stick it on top of the light sensor. Those lights are
surprisingly bright with the reflector that focuses the beam. They make the
light sensor values incredibly consistent! I have run my robot in my dark
basement, upstairs, shown it to friends at school, and at the competition
without adjusting my light sensor threshold at all. So, just a thought for
future light sensor applications.

| (...) How did you power the LEGO light Rob? Did you wire the light sensor itself to the light, thereby using the current that the RCX sends out to active sensors to power the light? Or did you use an external battery box? John (22 years ago, 25-Feb-02, to lugnet.org.ca.rtltoronto)

I was thinking for a tougher contest, beyond this one, we could turn the board up on its side, and stack the blocks. (...) (22 years ago, 26-Feb-02, to lugnet.org.ca.rtltoronto)
