Well, the project didn't even started yet, but I'm thinking on it seriously.
I see some problems in design because I'm a LEGO purist and I'm not sure if I can make it small enough to be of any use. Also, I don't know yet if I can devise a way to make it turn.
Anyway, I'm probably going start by testing the design in my room using two closets or shelves next to each other and see it adapts to the space between them. Then I'm going to make sure it can in fact run and climb by pressing against the walls of the closets. I don't know how feasible this might be, but I probably must demultiply the motors or it will not have enough strength for climbing.
For a real life test I was thinking in making it climb my chimney... After all it's Christmas, isn't it? *<||:-)

Anybody ever seen a similar project?

It sounds fine!

Two simple questions:

What the pipes are made of? Some materials can be a problem respect to the
radio link.

What kind of pipes are you thinking about? I mean, they must have a "big"
diameter to allow the bot to move inside.

I'm thinking in building a bot for exploring pipes and conduits with my
CyberMaster.

Here's the idea:
It must be small enough to fit inside a pipe and also to be able to make
turns without major problems (although turns are not my first priority).
It will "attach" itself to the walls of the pipe by pressing against the
sides of it with wheels/tracks in at least 2 opposite directions, and
pressing with enough strength to be able to climb a vertical pipe if
necessary (important!).
It also must be able to stretch itself to adapt to larger pipes at runtime.
I'm confident the CyberMaster radio link might be able to pick the tower
even on long pipes if I place it near the opening, so I might be able to
command the unit it by hand using a joystick or keyboard.
Later maybe I may be able to place a light and a camera on it. Of course it
would have to drag a cable behind it, but strength to do this should not be
a major problem.
Right now I'm more interested in creating the mechanics for this...

Comments?

I think it is a really good beginning. Just only consider a few facts. Let's suppose the bot is big enough to "fit" in the chimney (I liked the idea and it is Christmas). The bot is going to use one axis to move along the chimney... and you need (...) (26 years ago, 23-Dec-98, to lugnet.robotics)

(...) I wouldn't suggest this... if your chimney is used for normal purposes at all (such as fires) then the interior will be covered with soot, ash, etc. This will probably be quite a challenge for your little robot, and I can imagine it coming (...) (26 years ago, 24-Dec-98, to lugnet.robotics)
