LDraw Parts of HiTechnic Sensors and Multiplexers now available

A couple of months ago I worked with Philo on creating a complete set of LDraw
parts for the HiTechnic sensors and multiplexers.  These are now available for
download from the HiTechnic downloads page.  

Look near the bottom of <http://www.hitechnic.com/downloads>.

This LDraw parts pack includes all currently available HiTechnic sensors as well
as the two multiplexers.  For the Sensor Multiplexer, even the battery pack has
been modeled.  A very cool feature of this parts pack is that all the units now
have the text printed onto them.

Here is a sample image featuring the parts from this pack:

<<http://www.hitechnic.com/media/sensorlineupwmuxsm.jpg>>

A really cool thing about the text is how it takes the shape of the surface it
is projected onto.  Especially the IR Seeker has quite a bit of curvature and
the text is perfectly projected onto it.  Philo used his tool SlicerPro to make
this possible.

You can also see a couple of these sensors used in the building instructions
that are available from the models page: <http://www.hitechnic.com/models>

Just to be clear, when I say {"worked with Philo"} that means I sent him the
list of the sensors and the text that goes onto them and then he did all the
work.  Thank you, Philo!

DualGrip - NXT Rover (DG) - my latest creation

Hey folks,

It's been a while since I last made a bot.  My latest is DualGrip - NXTRover (or
DG for short).  I wont go into great detail as all info (with videos) can be
found at my site http://www.plastibots.com, but DG has both tracks and wheels
and uses an acceleration sensor to determine when it is climbing and deploys the
drive system to angle itself to engage the rubber wheels.

Question about gearing Power Functions-based trains

I've noticed that because the Emerald Night's two sets of driver wheels are
locked together, the engine struggles to go around corners: the outer wheels
have further to turn, so the wheels slip and the engine's movement becomes
jerky.

Would it be sufficient to drive the engine using only one set of drivers?

How about using a differential?

Either way, would there be enough traction?
