It is not clear what you intend to do.
But two cameras on one robot are normally configured to give a
stereo image (with depth), to simulate the two eyes of a human.
Displaying stereo images is normally achieved with shutter glasses
and with a software library like OpenGL. Use google for more info.

They do this all the time. One image is tinted in blue, and the other
in red, and you look at it through glasses with one blue and one red
lens. It does help if both cameras are looking at the same scene, of
course ;-) - which is what I assume you meant.
Another thing is that you could probably create an image on a single
screen that would look more 3-D than a single-camera image, by
calculating parallax differences between the images from the 2
cameras, and playing some fun-n-games with shading or perspective, or
something or other, during creation of the composite image. Not sure
how well this would work, but it sounds something one could play with
- [besides using the alternating shutter approach]. OTOH, it might
come out looking like something Picasso might have painted.
Ahha. In that case, I think you should have a split-screen. How can
you have 2 independent images without a split-screen? It would be a
senseless jumble if you try to combine them.
Some animals [although I'm not sure that rodents qualify] have very
little binocular overlap in their visual fields. Somewhere up high in
the brain signals from the 2 sides will come together, but probably
not in the visual system per se.
Predatory animals such as lions and eagles tend to have more binocular
overlap, since it helps in running down prey, while prey animals such
as deer and horses tend to have more laterally-oriented eyes, so they
will have wider peripheral vision for better detection of predators.
Rabbits apparently have almost 360 deg vision, IIRC. Dog eyes, evolved
from wolves, tend to point more ahead.
Although rodent eyes may seem to point to the sides exclusively, I
think there may be a small amount of binocular overlap directly dead
ahead. And I'm fairly sure this is true in squirrels, at least, since
they make their living jumping around in a highly 3-D world.
Rodents and similar "prey" animals do not have binocular vision -- they
don't focus both eyes toward the same point. They have a very wide
peripheral vision, almost like a Cinerama movie screen. The little
rodent brain stitches the two images together, and it's basically a
A robot could have two cameras, or an anamorphic cylindrical lens on a
single camera. It doesn't matter to the image processor that the picture
from the camera is all squeezed out and distorted, as long as the
distortion is known. If you're needing the image to be presentable to
humans, two cameras and a split screen would probably be best. Some
simple video manipulation could "fuzz up" the split so it's not a sharp
