Well just ran into some problems tonight... I think I need some filtering caps on my sensors... My range finder is calibrated, but doing very strange things...<div><br></div><div>Also my line followers I setup to be polled by the digital io out pins on the arduino (wanted to keep the i2c port free, only leaving me 4 analog in ports, so I wired 3 of them directly, and setup 5 more as polled inputs, using a digital IO to power the vcc on the sensor, and reading back the output... But either the digital out isn't able to source the current for the sensor, or I suspect the sensors wired to ground without a vcc are acting as a pulldown, basically pulling the output to zero regardless of which one is energized...</div>
<div><br></div><div>I might have to add an actual multiplexer to my circuit... </div><div><br></div><div>I'll bring the bot in regardless, and with some tuning might be able to get it in the ring, but I might have been a bit premature with my "challenge" lol...</div>
<div><br></div><div>Although any tips/pointers would be greatly appreciated lol... I'm kind of rushing this together and I'm suffering for it now. I'll bring along a paper copy of the schematic as well in case that helps.</div>

I wouldn't worry.... my new robot doesn't have much code in it yet
and I'm drastically underweight so it should be a good match-up. <br><font color="#888888">

<div>(I barely got my sensors working yesterday, and my range
finder is still badly unrefined) lol... but it will be fun
either way.</div>
<div><br>
</div>
<div>Also I have yet to add any traction to my tracks... (planning
on rubberizing them, but for now elastic bands will have to do
which likely won't work for long) lol</div>
<div><br>
</div>
<div>this should be amusing (and a great first round test) :)</div>

<div>Hey, I'm getting close to a working bot for my
ORE Robot Games Sumo entry (<a href="http://ottawarobotics.org/games2011/" target="_blank">http://ottawarobotics.org/games2011/</a>).
I was wondering if any other Lab members have bots
(either for this or past competitions) I could
bring mine in tomorrow night, and have a go ;)
(I'll loose horribly as it's not complete by any
means yet, but can be cool to try out against some
other bots to see where/what I need to improve).
<div>

</div>
<div>If anyone has a Sumo ring, that would be cool
too.<br>
