I am searched for some more powerful microprocessors and found ARM cortex a8 to be powerful specifically some by freescale and the i.MX but they all have expensive dev boards... raspberry is the lowest cost highet power i can find (700MHz clock, GPU and some more...).

Charmed Labs Pixy CMUcam5 (latest revision) should be available in November 2013

I think I said over a year ago that a Raspberry Pi would do it Since then I have written The Raspberry Pi for Dummies book.

I'll admit I missed the key post(s) that stated they didn't need real high fps or resolution. Moreover that the cost needed to be max $40. And yes that the solution was available, last eon...

I just got caught up in what the Pixy was capable of and thought it was worth mentioning in case someone else was searching in regards to a remotely similar application and was interested in a somewhat different angle.

sadly, the only way to use an arduino for that type of thing is by using a web cam conected to software
for image prosessing on a laptop or pc and have youre arduino connected to it. i wanted to do a simular
thing myself.

Or a Raspberry ("Raspberry Pi Zero as horse power coprocessor for Due?"):

Arduino triggers 90fps video taking on Raspberry Pi Zero already:


Tbd is gstreamer pipeline with self written plugin to do single frame modifications and feature extraction, and feeding this back to Arduino for (PID) robot control.

You get Raspberry 5M v1 camera for 8$ on aliexpress, and the NoIR version for night vision for 10$. With 4$ 3W infrared LEDs you are completely independent of external ligh conditions, this picture was taken in absolute darkness (click for details, or this thread):


Just to be complete, you need a 5$ Raspberry Pi Zero or 12$ Pi Zero Wireless in addition, as well as 3$ Pi Zero flat wire cable (from aliexpress). Of course you can use bigger and more expensive Raspberries as well.

Raspberry v1 camera allows for 640x480 videos @90fps (eg. this), and full HD 1920x1080 videos @30fps (eg. this).
