why does the axon have all male contacts and the arduino has all female contacts?
-
Female headers are easy to plug breadboard wires into, thus good for beginners. However, if you want to eliminate the breadboard, you usally end up having to build a shield.

Male headers are good for servos, sensors, and other related robotics peripherals that usually come with female headers. It's also a lot easier to work when power buses are easily accessible - with a 1x3 pin female cable, you get all the parts needed for data and power in one piece. Try hooking up a servo on an Arduino - the three wires go almost randomly onto the board.

How would you go about hooking up a servo with an arduino? Do you cut off the female head and put the wires in the correct slot, or is there a male-male part that can be bought?

You can build something like this call the Servo-bus to plug into arduino

To make building robots easy with Arduino, I have created the Robot Builder's Shield. You can get it from here:
http://robotxdesigns.ca/2010/11/08/the-robot-builders-shield-v2-kit/ (http://robotxdesigns.ca/2010/11/08/the-robot-builders-shield-v2-kit/)
This Shield lets you connect 2 DC motors, up to 6 servos and up to 6 analog or digital sensors and has a nice prototyping area where you can experiment with other stuff. On top of the prototyping area you can mount a Mini Breadboard for non soldering experimenting. You can use the built in Power switch to turn on your Arduino at the same time as the motors.
I have also created a smaller microcontroller board called uBotino, that has the same features as the Shield but without the prototyping area and with a smaller size (2x2"). You can program this board like a regular Arduino or you can use Webbotlib Project Designer. See it here:
