comment Which combination has a lower gear friction?
I'm not a mechanical engineer, so don't sue me if I get it wrong, but I think the looser the gears mesh the less friction is between them. Parallell gear setups would seem to have increased friction, but again, I could be mistaken.

comment Can you use a beveled gear as a pinion?
Honestly I haven't seen this kind of setup, but it could work. I wouldn't bet on it though. If you have more space in your vehicle you can also try using two universal joints at 45 degrees each and see if their backlash is less than the two bevel gears'.

comment Can you use a beveled gear as a pinion?
You can certainly do that, I can easily imagine a setup with a vertical servo, a gear attached to its shaft, and a rack turned 90 degrees to the side. The only problem I could imagine is when in the extreme positions the plane of the rack could move away from the shaft, possibly disengaging the gear.

comment What is wrong with a Lego pneumatics system that won't go?
There is still the possibility of either stuck cylinders or deteriorated seals. Can you feel or otherwise sense air escaping the cylinders? If not, then they seal well, but might be stuck. In this case can you move them by hand? If they can move under pressure and while being assisted, then they might need just a few (or a lot) of these assisted cycles to even the lubrication inside.

comment How do I control one EV3 using another through bluetooth and LabVIEW?
This is not EV3 and does not use LabVIEW, but maybe you can use it as a reference to develop real time Bluetooth communication between two systems: philohome.com/nxtjoystick/joystick.htm
