Is there any way to tell by just looking at a wire what AWG it is?
Some of the wires I have like jumpers are non-standed and some like those that come with the batterypack are stranded. I realize that non stranded wires are breadboard friendly, but other than that, is one prefered over the other?

stranded wire is usually used for things like servo extenstion wires and such because it is more bendy. it is also used for high voltage applications.

Thanks trumpkin, that makes sense

thats because engineering "makes sense" lol ;D
I guess that if you have a lot of experience you can tell the different wire gauges. Like I can tell the difference between an 18 gauge and 22 gauge pretty easily by feeling it, but if a wire is really really thick then its a really low gauge wire ( less than 16)

sometimes it's written on the wire . . .
otherwise strip off the covering and measure it with calipers ;D

stranded is more flexible so its good on sensors
i went with 22awg for my $50 robot, but if I were to do it again i'd buy 24awg stranded.

Stranded wire tends to break off easier when soldered to a board. An easy way to combat that is to put a dab of hot glue on the connection to form a sort of strain relief.
