This is a google talk showing a neat new possible robot camera.
Basically it uses an arrayed chip and a laser with a high speed clock to get 128x128 range data, and then combines each pixel with the pixels on a normal color camera to create neat 3D images.
Unlike other LADAR technologies, it allows for instant highspeed 3D images without moving parts. Oh, and iRobot recently bought this company . . .
The talk is 60 minutes, but its worth watching.
