--- Thanks for the reply,
 I'm currently in Iraq serving our Great Country.
As for mobile robotics most of the time it was something relatively 
simple. I built a platform using 2 hobby servos as drive motors
(modified for continous rotation) with a swivel wheel in the back. 
PWM to control each motor for skid-steer like steering.
 Bumper switches in the front for close object detection, sonar for 
distances up to around 5 or 6 meters, I2C interface for a small LCD. 
Nothing very fancy, just a mobile "test bed" to practice coding and 
interfaces.
 As far as prices if you want to use off the shelf parts and boards 
something small like i described (around a foot square)could be built 
for around $200. If you want to build your own boards and interfaces 
you could get going for less than 1/2 that.
