Question about motor sheild for robot

Hello, I am building (or want to build) a basic wall avoiding robot based on the 4WD platform availible in the makershed. This comes with 4 seperate DC motors. In additon to these motors i would like to power a servo. All of the motor sheilds i have looked at so far seem to only be able to power two DC motors and no servo. How should i go about this? I want to, but this is probably not possible to also add an LCD screen? Can all of these external parts be added? Is this possible? If so, how? Thank you

Nice of them to call it Arduino powered, and then not give any info about what
to do. I dug this up - if it’s the same platform:

Just keep looking.

This shield (originally from adafruit) can do 4 DC motors (or 2 stepper motors) and 2 hobby servos at 5v: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=292.

You should be able to control the LCD via an i2c serial connection.

Unlike other motor shields, this one looks like it is stackable, presumably for more motors http://www.robotshop.com/arduino-compatible-mega-motor-shield-1a-5-28v-4.html.
