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.
