Well spotted Brian :-)
The electric elements are those that will feature in the new Bulldozer. The
rest of the MOC is parts from my own collection, NOT the rest of the
Bulldozer! (that many beams with studs would be too much to hope for :-) )
Two large motors (with great torque!) do the tank drive on channel 1, with two
smaller motors doing the stilts at the back, to tip the robot up for picking
up objects) and the grab at the front on channel 2. On a single handset you
change channel to select the different functions in pairs.
For automation, the centre of rotation of the handset levers is aligned with
one of the beam holes on the side, so you can have a motor controlled by one
handset move the levers on another handset. This means you can have
sequential automation and all sorts of fun! The system can branch too, by
having more than one receiver set to each channel number. It could also do an
“OR” function by having two handsets transmit on the same channel (OK as long
as the directions don’t conflict).
There is also my experiment in fitting the large motors to a walker chassis,
where the great torque comes into its own:
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=226243
This robot has enough torque to buck if the legs are aligned rather than being
opposed, but it can make the 24-tooth cogs jump on the axles! I think the
large motors are what many fans have wanted for years. The jumping of
24-tooth cogs was why I used 12 and 36-tooth cogs for the rover.
More MOC pictures built with the bulldozer electric elements (battery box,
handset, receiver, large and medium motors) will appear in my Power Functions
Brickshelf folder (when moderated) as I build them, so this is the space to
watch :-) http://www.brickshelf.com/cgi-bin/gallery.cgi?f=226241
I advise saving up for as many bulldozers as you can carry! (BTW I don’t have
the kit).
There are some differences between the RCX, IR Train and Power Function IR
systems. I’m not an expert in that but Stefan Vorst has worked it out in more
detail.
There will be some compatibility of the Power Function system with the 9V
system, such that you will be able to drive a 9V motor or light from a Power
Function receiver or battery box if you use the right elements. I’ll say more
about that when I can. This compatibility is something we AFOLs have pushed
for and shows the benefit of us being involved.

Wow mark, thank you for the info on this really cool controller and all of the
pictures we would otherwise not see. I personally can’t wait to get my hands on
3-4 sets but until then I’ll have to keep wiping the drool off my keyboard.
A few comments:
I’m not a huge fan of IR-rc because of its directional limitations but it’s
something I can live with and i think others agree. I can see this system being
used in several themes including TRAINS, as it is a pretty cool solution the
extremely limited train IR system. Now granted it’s still IR and not RC as most
would prefer, but I’ll take what I can get as it’s still a cool product.
Some have commented that they don’t like the integrated wires but I see this as
a plus. There are a couple of reasons for this but for the large part it will be
nice to not have to hunt for wires to connect everything. Now I’m not saying
they shouldn’t offer extension wires but for compact projects and or tight
spaces integrated wires is a good thing.
inny’s!!!!! I was a very happy camper when the monkey set came out several
years ago with an inny for the output shaft on the motor and I’m glad to see it
stuck around. This seemingly simple design change makes the motor harder to
produce but it increases its usability by 100%.
That motor is huge! I’m not sure I’ll get much use out of it in the train world
but robot builders are going to love it. It makes me want to start building
techinc models again or at least that 1/16th scale M1 Abrams tank I’ve wanted to
build for years.
I’ll wait for Stefan Vorst to chime in for info on IR compatibility between
systems but I do have several questions I hope you can answer.
questions
- On the controller I noticed that there appears to be 4 channels. Is assumption correct?
- Does this system act like an on/off switch or does it have some limited speed control?
- Does this system use 3 batteries or 6? i can’t tell from the photo
- In set 4958 “dinosaur” which also uses the same IR control system, there seems to be something white that looks like either a small sound box or small motor. What is it?
- Will extension wires be available?
- Did you happen to check the range on the controler/reciver?
- The hacker in me has to ask: is the receiver unit glued, screwed or snapped together?
- I noticed little black switches next to the main controls on the controller. Are these to fine-tune the controls much in the same way as RC controllers and if pushed to the extreme will the controller remain in an “on” position?
Ok I’m sorry that was a lot of questions. I hope you don’t mind. I’m just
extremely curious.
Again thank you for the photos and the info as It’s extremely appreciated,
Ondrew
