Robotics, consolidate all your sensors and controllers onto Ethernet. Its quite hard finding a microcontroller with good Ethernet.

I've had good success with the NXP LPC178x series. Cortex M3 with onboard Flash and SRAM. Ethernet is onboard and easy to attach with a simple PHY, also works well with extenral SDRAM and expanded Flash.

  yeah I also used that a while ago, but I don't think I can fit an ethernet client for Robotic Operating System on it. Doesn't appear straight forward anyway:- http://mbed.org/forum/bugs-suggestions/topic/2662/?page=1#comment-13870 http://mbed.org/forum/bugs-suggestions/topic/2662/?page=1#co... Hmm, that Xport product is £50 from mouser. Not bad

    I don't quite understand mbed. It seems...toylike. I've been using ucLinux for 1788-based stuff. You get the full stack with that. The other option is something like the TI CC3000, a serially driven wifi module. Adafruit just launched a cheap breakout module. http://www.adafruit.com/products/1469 http://www.adafruit.com/products/1469

      everything we do is in volumes of 1. What is the dev board you use? Mbed is quite convenient for us doing random 1 offs. EDIT: also can't find evidence of a ROS client working on ucLinux :(

        For LPC I've prototyped on boards from Future Designs, like this one: http://www.teamfdi.com/development-tools-kits/products/1/DK-57VTS-LPC1788 http://www.teamfdi.com/development-tools-kits/products/1/DK-...

The arduino yun [1] combines an linux-based SoC with a microcontroller on a single board. So you can have both, networking and applications in practically any language, and an internal interface to a microcontroller. For only accessing a rs232 serial port over ethernet, there are easier solutions. But if you need multiple of such ports, sensor access, etc. its quite a nice combination.
