[TC6] Technic SBrick Contest - Information Topic

[Epic Technic]

Here is the complete SBrick LDD model: http://www.brickshelf.com/gallery/Epic-Technic/stuff/sbrick_model.lxf

EDIT:

On a side note, I see a potential "flaw" in the SBrick's design: You cant use the lower outputs (lowest "stair step") on the brick to power two motors for each output without using an extension wire

true...but it still works anyway using the extended wire...so we will be fine

[Seasider]

Can you post the dimensions of an s brick in the rules so we can make a space for it as it says the model must be ready for an s brick ... Or if we place 2 ir units side by side is that the same size and attachment ?

Also on the 4 function motor thing, if you went for a tracked of skid steer does that count as 2 functions. I think it does, I think your intention is for separate functions and this fits that. As with a car you'd have drive and steering, with a tracked you have drive to 2 tracks, so both the same

not a big deal as you will anyway use 2 motors, 2 IR/sbrick slots, and 1 remote control....so it's clearly defined as 2 functions itself. Let's see is as "one motor powers a track therefore it's a function, the other motor powers the other track so therefor it's another function!"

I think the easiest way to put it is "you must use four (no more, no less) of the outputs on the SBrick(s), regardless of the amount of motors." There really is no room for misinterpretation there.

I'm guessing that there can't be a 5th PF motor attached directly to the battery box for a fake engine... Or what about LEDs?

I shall finally be able to enter one of my tanks into a contest.

Be aware that the MOC should be new. No existing ones.

LEDs have been described in the rules. LEDs are okay, but they don't count as a function.

I'm just planning, as most of my models feature this function, now I will find a solution using differentials.

[Jeroen Ottens]

I suppose a video showing the functions is mandatory this time?

[Erik Leppen]

It's in the original post Jeroen.

Please read before you write. ;)

Same goes for Tommy's LED question by the way. It was answered before you asked.

Jim, great contest, and I may have time to build this time. Just to be clear, the 41999 has four motors, but two are for drive, one for steering, and one for winch - this would qualify if it was new, but is this 3 functions or 4 - I'd count 4, as the two L motors are not connected by gearing, but are connected to the same IR receiver socket.

My plan is to build with two IR receivers, to test the functions, these could be replaced by one S-brick with no change in aesthetics.

This is something we need to finalize.

I'd like to think of Driving as a single function, independent of using 1 or 2 motors. (this conflicts with my current rules I guess)

Skid steering/driving is a tough one as well. Although using two motors in skid steering will take care of driving AND steering, ending up in using two motors for two functions.

[Eraman]

It's a good contest again!

I don't understand exactly:

"When using a gearbox, your model can have more than 4 functions (6 for example, like the 8043 Excavator).

The model needs 2 PF IR Receivers which can be replaced by one or two SBricks."

....

Model needs EXACTLY 4 powered functions (no more, no less)."

Which is the right?

i think this is the best solution:

use exactly 4 PF motor, and make minimum 4 function powered by the motors.

If you want to use gearbox, you CAN use it, with it the functions limit will be max 8(or 6 if 1 motor change the gears).

I have a question: can we build extra MANUAL funtions(above the 4 power function)? For example: cabin tilting, headlight tilting, etc.?

It all depends on what the definition of a function is.

Driving is a function, but this can be accomplished by using two motors. That's the caveat.

You can have manual functions. I already answered that question.

Ok, my plan:

4 motors, 1 motor change the gears, so i will have 6 power function(with 3 motor), 1 function is steering, 1 function is driving and 4 other functions. Plus i will have 1 manual function, cabin tilting. Is it good for this contest?:) I hope, yes:)

[Jim]

I think the easiest way to put it is "you must use four (no more, no less) of the outputs on the SBrick(s), regardless of the amount of motors." There really is no room for misinterpretation there.

Maybe this is indeed the best description, which boils down to using 4 motors!

Yup! That's cool

Hmm, otherwise, use only one motor for driving, if it isn't enough, make lighter(smaller) model.

Or the driving will be an exception when you can use 2 motors, other function have to be powered only one motor.

Right, i agree with you, max 4 motors with 2 Sbrick, and fuctions are minimum 4, maximum unlimited!:)

Just to be sure, it's not allowed to use more than 4 motors? For example i can ONLY use 1 motor for driving, 3 other for functions. Bassicly 1 motor per function?

[D3K]

Not necessarily, I actually meant you can use two or more motors on one output if you so desire, but you are limited to the four outputs of one SBrick. Seeing as it is an "SBrick contest", this will help showcase the possibilities of the SBrick (not having first hand experience, I have no idea how it performs with more than one motor attached to a single output).

In effect you will still be limited to one function per output, as it's rather difficult to power two different functions with the same output

EDIT:

So in my oppinion, if someone wants to power 10 motors from one output, please go ahead.. I don't think the maximum number of motors will be the deciding factor on who wins, rather the opposite

How about "Use exactly 4 motors (and do with them what you want)"?

This is more or less what you mean.

Why not "Just make a model that fits nicely with the same way of operation of 42030 or 8043". Is that so difficult to interpret? We can endlessly debate about the details, but let's adhere to the spirit of this contest, right?

To be honest, I am having an idea, but it requires a manual function (or five controls). So that means currently I can't do it. And I don't even really care if it's "allowed" - it's not in the spirit of the contest to have a manual function.

If you build something that's not in spirit, you won't get as many votes.

It looks like the spirit is to build a remote-controlled model that has four controls. So, I say: let's just build a remote-controlled model that has four controls.

Why don't you use gearbox, like me?

[Milan]

Somebody will use gearbox, somebody will make one or more manual functions, some will stick to 4 functions. Great thing is that we have a choice.
