Hey, I was wondering if anyone knows where I might obtain a CMUcam? I have checked quite a few stores but they all seem to be discontinued. Is this because there is a new model out? Or is it because there is a better device on the market? I have looked into a NXT CMUcam but am not sure if I will need NXT to use it or if it will be able to communicate with my hardware directly without the need for an external computer. Is there an alternative to the CMUcam which is equally powerful and easy to program?
