Well I got my FT set (Robo Mobile) -- I have to say I'm a bit disappointed.
It doesn't seem like I can build anything that isn't more or less a
variation on the core design of the set.  To get enough pieces to do
open-ended MOC's, you would have to spend thousands of dollars.

Plus, when you get down to it, I don't really want to re-learn all the
tricks I learned for Lego.  I'm a bit surprised at how much knowledge I seem
to have internalized around the Lego mindset.  It's not easy to change
horses midstream, as it were.

Anyone want to buy a slightly used FT robot set?

There are a couple of areas where FT does outshine Leg a little.
Namely - Pneumatics - FischerTechnik has a larger range of cylinders,
more advanced valves, serious compressors, and most importantly
solenoids.

Also their robotics controller has a great deal more in terms of IO
flexibility than the RCX. Although it appears to be somewhat larger.

I agree that their designs do mean that things slide around a bit -
and have to be braced harder. I havent used it for a while though -
but I seem to remember that the gear fixings were based upon grub
screws. It is possible to build cross-system models with them both,
and the push fits of Lego pneumatics are compatible with the FT
pneumatics.

On the European/UK website some of the kits have handy PDF part
catalogues - something that it would be handy for Lego to do, although
we do have Peeron.
