What exactly is this robot for?

Like said in detail in previous posts, this is for building inspection, where a rigid endoscope probe like this one is not suitable for the task.

I'll show more details and some photos of the place to inspect to people who can realize what I need.

Hi there.

You mentioned walls, so are we talking about moving vertically within a 20mm gap between inner and outer walls?

(Interesting project, btw. and definately within the realms of possibility with the information you have given so far.
I have an FPV setup that uses a camera that is 9 x 9 x 11mm.)

No, the device should move horizontally.

Well lets have a look:

15mm is doable, but with regular gear motors it will only give you a mm or two of ground clearance.
Being an FPV platform it'd likely want to be 4WD to give a steady base with good control.
Needs to be reliable as you don't want constant maintanance. Should be easy enough with 100rpm motors and Neoprene wheels.
Will also want a good run time and weights not really an issue, so something like a 470mAh 2s would last you plenty of time.

Alex routinely designs and builds chassis for people, and I provide the electronics, so between us we could probably build something that fits the bill if someone knows of a suitable camera.

If a suitable camera is found and electronics from Rory I can certainly design a chassis for you.

The camera is not a problem, I have already found many.

What I need to know is if device can use a single onboard wireless transceiver to transmit both rc commands and wireless video or two separate wireless transceivers: I suppose that only the second option is possible.

[Shakey]

The second option is the easiest and probably cheapest.

An example of wireless 2,4 Ghz micro camera:

I already have a standard 2,4 ghz video receiver that should be compatible with any wireless camera.

The problem with using a 2.4GHz video feed, is that the controller for the robot also runs 2.4GHz which can cause a lot of interference on the video feed. For this reason, a lot of aircraft FPV systems have moved to 5.8GHz video feeds, which are much clearer.
