The answer is no, the Eyes were not 3D cameras.
For tracking a TV you don't need a 3D camera, nor do you even really need a colored camera at all. (see duck hunt and the light gun). It appears that the eyes in ROB were purely light sensors. If the sreen flashed a certain code ROB executed it. There were 6 codes that ROB could respond to.
Besides, 3D cameras are purely any 2 cameras mounted in a known configuration that can then be used to compose a 3D image.
