I/O Board for Mobile PC-Based Robot

Let's say I want to step up (more like a quantum leap) and make a robot out of my Acer Aspire One, along the lines of Evolution Robotic's discontinued ER-1 robot, which was a mobile laptop-based robot. It's got a camera, vision, tons of memory & processing power, and I can finally use my RoboRealm software.

I need a Windows-based USB-based I/O board that lets me connect lots of A/D and D/A converters, external sensors, servos, motor drivers, etc. And it has its own software, and lets me program in my beloved BASIC. Not just a servo controller or motor driver that gets programmed one time and does its own thing, but one that lets the PC do all the computing and thinking. Hopefully in the $100 aisle...

Anybody know of a product along these lines?

    You could use Parallax's Robot Control Board and add an additional board with an ADC chip. Any microcontroller board could work; you may need to add a USB to serial converter. It is just a matter of software--famous last words. PC sends several values, e.g., left motor speed, right motor speed, pan servo setting and tilt servo setting. The IO cog reads those and updates global variables that other cogs use. Then the IO cog sends variables from global values updated by other cogs to the PC, sonar 1, sonar 2, bumper switches, etc. Repeat until battery dead.

    Here's something that might get the creative juices flowing.

    I found http://www.awce.com/gp3.htm which is a little board with ~16 I/Os, which isn't enough for my intentions, but the kit is a good value at $35. Might be useful for someone out there!

    The Arduino Mega has quite a few I/O: http://arduino.cc/en/Main/ArduinoBoardMega.

    You would probably need a shield for motor control. I'm not sure if there's a free BASIC compiler available, but I believe that commercial compilers exist. You would also need a programmer if you went the BASIC route (~ $35 for AVRISP mk2).

    This looks interesting for $39:

    If Shipping from the UK wasn't $23 (15GBP), I would have ordered one already!
