Last night I took apart my Microscout just to see what was going on...

Unfortunately, my pictures look like crap, so it'll be a few days before I post
those (at least, the closeups of the guts).  In the meantime, you'll have to
suffer with my equally crappy ASCII pictures...

The thin metal strips are brushes.

Look at the side of the brush plate with the most metal showing.  One set of
brushes (bottom brushes) should be vertical and at the bottom.  The second set
(side brushes) should be horizontal and on the right-hand side of the
brushplate.  The side of the brushplate without metal is the "motor side".
Their are two opposing clips on the brushplate.  One clip is next to the "side
brushes".  We'll call this the "right side", and the other, appropriately, the
"left side".

                        _________       # denotes metal.  The perpendicular
lines are the brushes.
                       /###   ###\
                      |### ... ###|
Left Side Clip --->  [|###|  _|###|]  <--- Right Side Clip
                      |###'.|.'###|
                       \###___###/

The motor's "bottom" has rectangular mounts that fit into the Microscout casing.
(They can be seen from the outside of a fully assembled Microscout, if that
helps).  Here's ASCII of the relative key shapes:


                              o        <-- Commontator Shaft


                         |_       _|   <--- Motor Mounts


1)  The little shaft sticking up out of the motor is a commontator.  Set the
motor so this side is up.

2)  Gently set the brushplate over the motor and clip the LEFT SIDE down first.
Very carefully move the brushes to fit around the commontator, but DO NOT BEND
THEM!  (I used a precision screw driver).  The brushes are forked (like a snake
tongue), so make sure both are adjusted.

3)  Carefully clip the RIGHT SIDE into place.  Do this little-by-little,
checking the brushes to make sure they aren't being improperly bent against the
commontator.

When I played around with mine last night, I only worried about the brush tines
that were closest to the motor body and then properly set the tines closest to
me after clipping the brushplate into place.


Proper placement of brushes will look somewhat like this:

               ___________
               ***
            \ *****              The lines are brushes and the * make up the
com.
             \*****              Both brushes will bend slightly.  They are
              \***               purposely not tangent to the commontator.

Good luck!  If this doesn't help, I can send you the current pics I have (even
though they are blurry/crappy).

Hmm... Well, you could try www.mindstorms.com (or whatever it is) and look
fo the
configuration.  I remember looking around that side and seeing some diagrams
and shematics.  I have that set too, and I have no intentions of taking it
apart (lucily)

One day, while there was nothing to do, I took apart my Microscout (came
with the R2D2 droid development kit, or whatever).  I had no idea how the
motor assembly was connected to the rest of the unit, so this was probably a
bad idea.  Anyway, I took the motor off and can not reassemble the unit.  On
the plastic piece to which the motor was attached, there are two sets of
thin metal strips that come in contact with the motor shaft.  Does anyone
know the correct configuration of these strips?  I'm not very hopeful, but
this is currently the only motorized Lego item I have.  I'm looking forward
to getting RIS 2.0 soon.  I'd like to have a motor to play with until then,
but if nobody can help me that's fine.  And yes, I'm an idiot.

Thanks very much for the information, but I don't have the Microscout in front of me and won't be able to get my hands on it for a while. I'll probably have RIS 2.0 before I get to my Microscout. When I do get it, I'll give it a shot. Again, thanks (...) (22 years ago, 18-May-02, to lugnet.robotics)
