Kunal,

Don't know what your email address is... but you might consider a VIA EPIA M10000 Mini-ITX board with an embedded 1GHz VIA C3 processor. Price is reasonalble, size is great and power draw is less.

Is that enough processing power for you? I understand some of our customers are doing vision recognition on these boards.

You can check out VIA's robot related info here:

Hope that helps.
