how can i made car robot

 centrifugal clutch , with a high stall speed

 so motor can continue to drive the

 other accessories .

 A small solenoid can lower stall speed

 so you can accelerate more slowly .

 The solenoid can even rotate with the

  clucth ,( as Airconditioner clutches do .)

   Its bad idea to power all your stuff with

 just a battery .  So keep the motor running

 and generating electricity .

  Im playing with BW , CDD 300K-Pixel
 cameras .  They are analog , so i'll
 put comparators on each scan line ,
 and differentiate the scan line , looking
 for edges .  MCU will send a charge
 to a small cap , on the comparators
 "Vref" input .
  This allows the image to be "preprocessed"
 so the MCU wont need to do as much
  work .

 I expect several microseconds response
 time .
  Many people do it all in s/w and find
 its far too slow !

  You must allow the comparators to
 make a value judgement about a sharp
 image , as it moves about .

  Next problem with cameras is shake .

   I will use a front surface mirror , and
 move it will solenoids , in a jerky fashion .
 Somewhere in the sum of the 2 motions
 Camera/mirror , there will be a place where
 an image will be clear , in spite of very
 high camera movement .

 Camera is a low cost . It has a adjustable
 integrating period , which acts as a shutter
 and an iris , if there is blurr , MCU , sends
 a command to shorten the integration
 period . This also lowers the light reaching
  the CCD .

  The big excitement is the software .
  Ever since mcu's dropped in $$ , and
 up'd the perf' 500% , ive been , hopping
 for a spare monent to create an 8KB
  OpSystem for the ARM 144 pin CPU .
  Now i have a pile of hardware of all sorts
  EVB's to NDS Lites .

   The instruction set is nice , only the
  T.I. 430 has a better one .  But it has
 other draw backs .

  You can buy an ARM7 with 64KB or 98KB
  of high speed built in SRAM and it has
  power lower than any external SRAM !
    This makes it 10 times faster than
  a Z80 or MicroChip or Rabbit or ....

   So ! Join the project !  Buy a 65KB SRAM
  ARM from www.microcontrollers.com /
  www.ucPROS.com .
  click ARM , BOARDS , ARM7 .....
  I dont work for them , i bought from
  www.armkits.com , and got ripped ,
 i bought 2 GP2X's and got ripped ...

  Microcontrollershop is the only name
 left on my approved buyers list !

 I emailed Sparkfun.com , 4 times , but
 they dont answer , they dont want my business.
   I had trouble with
  www.gamersection.ca , they have  bad
 policy , so i bougt form GP2Xstore ..

  They dont care about keepping customers
 only about getting govt subsidies ..

  BTW , i think i can do a parallel port
 on a NoteBook computer , simply decoding
 the parallel at the USB MassStorage box .
   If i send a copy to USB-HDD no harm ,
  the file just gets rewritten , but my logic
  chips will decode and grab it as data , sending
  it to my ARM project mcu .
   I will not need to send data opposite direction ,
  cause what can you say to M$ WXP ?!!

  I'll instead store on SD card .

 Ah ! What would Robots be without
 computers !!
