Sometimes you want to add additional sensors and actuators to your robot. These sensors and actuators have most of the time interfaces like SPI, I2C, etc.. With a standard controller, you might run out of peripherals for that. This is where you can use virtual peripherals to connect an almost unlimited number of additional sensors and actuators.
Arduino Users can program MultiCore
It is a lot of fun to program your project on a MultiCore environment. Play with it and maybe you have ideas how to improve it and how to improve the programability. The board offeres already 140 MIPS, which is a lot for such a small chip, but once the community agreed on the right system architecture, we can make an ASIC out of it.
FPGA Users ...
FPGA boards are more expensive than simple µC boards. I think that the LCFA board with its FPGA, HS-USB and half a Gig of memory is offered at a fair price. Not to forget that you don't need a download cable. Additional, a lot of configurations will follow (MSP430, OpenRisc1200 etc.), so this board will offer a lot of fun to FPGA nerds as well.
I hope this makes you a huge fan and a great baker of this project.
@suarezvictor: Thanks for the link it's been some time since I looked at Propellor, I may have to dig my eval board out and see how it works side by side with Thomas's project when it gets fully funded on Indiegogo.
No need for Google. I first looked at the most obvious places, the Arduino article at Wikipedia and Arduino's official web site http://arduino.cc/. Oddly enough, neither explains the origin of the name.
