Hi india,

I think you have a few options here.... What kind of processor are you using on your robot?

Theoretically speaking. The easiest way would be to get a camera with wireless communication (usually analog) and a receiver on the laptop side. If you don't have camera with such capability then you are stuck because your controller probably won't have enough power to compress images into a video stream. Thus the only option left is to send separate images which might be slow. This is how I see it, not that I've tried anything with cameras.

dude
use a cellphone with a cam and gprs J2me is freaking built for things like these. if distance is not too long u can also opt for bluetooth with a bluetooth dongle
