One can make low cost compound eyes and use ARM-7 mcu's
to send control signals to actuators .

But you must not use C++ , nor Linux to program it !!

All glass diodes are light sensitive . And IR diodes are low cost .
the remaining problem is to hook a mcu GPIO to each ,
20 years ago , i saw DRAM with a window , bits would high
where light hit , and bits=0 where it was dark .
Makes a good compound eye ...

Why not let Robot program itself . !
Like a CT robot , you put a black bar in front of your
robots compound eye and move it quickly left .
Now you move the joy stick attached to the robot , to
the right , which programs the mcu to react ,move right .

The robot has ARM-7 mcu , times 4 , eac has
64MB Flash and 2 MB SRAM ( AA batteries ) .

Each diode in the Eye , can be hooked to a timer out w/ RC / GPIO
Input
or a PWM out or....
because there is no need to be precise , U dont need to
use the 10 bit ADC ! Its a compound eye , it only needs
4 bits .
I worked on missles , and it was grossly belabored to digitize
and figure what the camera was "seeing" , then react .
Thats how i came up with a compound eye idea .
But unfortunately , there is no surplus Eyes , to help .
ALL, GoldMine , BG Micro have none ....

But long ago , i saw a tiny DRAM that worked like a compound eye ,
you only needed to read the memory locations sequencially ,

Does anyone know where i can buy these DRAMs with windows ?
A CCD camera is digital , i need analog . If i could get a small CCD

that outputs analog , then id turn that to 4 bit ... But CCD's
convert
to 12 or 14 bit digital ....no good .
