Camera technology is always being used/tweaked in one way or another to yield surprising or novel results. In some cases, that means creating a camera that sees like a bug's eye. In others, one that perceives only motion, like a retina.
The most recent camera innovation we've stumbled across falls a bit closer to the second of those. It's called Pixy, and it's a color-detecting camera that might some day soon be the eye with which your friendly neighborhood robot sees and interprets the world.
Talking about robots, this low cost camera does not take your typical picture. Based on color. this camera will track it and send information about where the object is, and with no time wasted.
