This devices wants to be made into a robot

This micro laptop is so cheap (75 bucks) I had to mention it here. Seems like a great base for a robot's brain.

How would you propose to interface the robot hardware to this device ??
Low cost is not the only requirement.

I think you better look at USB device vs. host.
This USB port can not control any USB device. Its input only.
Good Luck, you'll need it

Welp, just like any other laptop I would think. USB to RS232 converter for servos and optionally bluetooth / WiFi via CF card adapter (or USB dongle) for wireless PC control.
The problem with my current laptop-based robot design is that most laptops require 18V and are very power hungry. This really complicates the battery and auto-charging situation. (that and the fact my laptop just died).

Hey Howy .. I think you should go for it. Although it shows not available anymore .. if you can get it im sure you can make it speak to your hardware.
Im not sure where he saw that it WASNT a usb host. But even if it wasnt, you can always use the serial port.
good luck
