Camera processing takes a lot of memory. As far as I am aware XP with 2Gb should be able to run ARC with camera functions however ARC has been updated since I last tried it and since I last saw any posts about the camera and XP. It's a common problem on Vista machines but that is highly likely to be an issue with Vista.

ARC is also unsupported on any OS below Windows 7.

Best option Add more ram. Upgrade to Windows 7 or Windows 8.

You could try (but it still may not work) Remove any unrequired applications, turn off any fancy graphics in XP

Hey thanks for the reply, i think i may drop back to an earlier version of the ARC or look at other options such as Robot-Realm for vision control.

I liked the idea of EZ-B in the early days but having to have a full blown PC with Windows 7 ( mainly just to have the graphical interface ) is starting to bug me personally.

I have other bots that run other devices ( from Lynx-Motion , the Atom Bot Board and Serial servo Controller ) and i may return to them.

Thanks again for the reply.

One thing is Windows XP is out of date. My advice is upgrade to Windows 7 or 8 but not Vista. Vista is trash.

a famous quote: "I believe robots will one day take over the world, as long as they're not running Vista"

Agreed Vista is garbage.

Thanks for the input, i decided to use this

Acer Veriton 1000

Quick Specifications

Processor Intel Core 2 Duo E6300
Memory  2.0 GB 
Hard Drive 80.0 GB
Operating System Microsoft Windows 7 Ultimate
Optical Drive CD-RW / DVD-ROM combo - IDE
Graphics Processor Intel GMA 3000 Dynamic Video Memory Technology 4.0
Graphics Controller Integrated 

seems to work ok

Just to clarify one point that I only just noticed, it doesn't need a full blown PC just for the interface, the power behind scripts, auto position, camera tracking etc. etc. etc. is all done by the PC. Without it you wouldn't have nearly as powerful a setup and definitely not as easy to work with.

As your project gets more complex you may find some slowdown with only 2Gb RAM, it may pay to either upgrade that to 4Gb or downgrade W7 Ultimate to W7 Starter (or remove services and applications etc. that bog it down).
