the original IgORE | IgORE2 | MiniORE
So, what is an IgORE?
First, IgORE doesn't actually stand for anything, other than the ORE part anyways.Just for the benefit of the newcomers out there (yes, we know you're there .... ), IgORE was the small square computer board found on the mini-sumo's. It was a project put forward in the fall of 2002 that brought out a whack of new people that participated in a build. It was a lot of fun to build, and is quite powerful.
The board was designed to have the maximum amount of expandibility and use, based around a MicroChip PIC processor. It was originally meant to be for SUMO's but can legitimately be the brains for something like the NerfBots, or any other 'bot.
Besides the hardware, a number of people built software libraries in 'C' specifically for the board. (although it can likely be used on any 18F452 based board), and it got a lot of new people started.

The MiniORE board
Our latest robot controller. The MiniORE is a 2 layer design, with chips mounted both on top and bottom of the board. It is based around the Microchip PIC18F2620 controller. The board is very full featured:
All in a 2 inch by 2 inch board.
Chips to get:
L293D hbridge samples (PDIP package)
MAX3232CPWR (actually any MAX3232 as long as it is TSSOP package)
or you can sample the MAX3232 from www.maxim-ic.com
There is also a good free C compiler for the PICs available from Microchip themselves.
Or you can use the amazingly diverse CCS C compiler.

This is a revised edition of our original IgORE board, with
a smaller foot print for the microcontroller, while utilizing the I2C bus
for peripheral chips. This board will still fit inside the mini-sumo size
constraints, but has plenty of power for larger robot platforms.
The Igore2 code
is the same as the Igore1 code but with the timing
values changed for 40Mhz operation and some code added
for the I2C expansion IC.
