Here is something I built for the MCP Program, using exclusively parts from set 31313: This is Santa Claus' sleigh, pulled by his faithful reindeer Rudolph! Rudolph pulls the sleigh by using the same leg mechanism I came up with for : a simplified version of the Klann linkage. Besides the large motor for walking, there's another one for (very roughly) adjust the angle between Rudolph and the sleigh to allow for curves, and a medium one for making Santa wave his arm.Of course, Rudolph has to have a red nose! The colour sensor, set for reflection mode, gives the nice redness. Like with , I made a point of using the infrared sensor "upside down" for Santa's eyes, to avoid the "aggressive" look given by the lines printed on the sensor. I tried to have the EV3 prominently displayed, with its side ports for USB and SD unobstructed, and reserved space for the rechargeable battery.I really like how the robot turned out to look: it was fun trying to make the most of the 31313's relatively limited assortment of parts (for example, some dampers for Rudolph's hooves would be most welcome). On the other hand, I really wasn't able to make it work well: with an EV3 loaded with batteries, a large motor, a medium motor, and assorted parts, the sleigh got really heavy for Rudolph to pull, even with wheels underneath. Also, the steering is just too abrupt for direct remote control, and I couldn't find a way to gear it down while using the available parts and still look cool. Here is the video of it in motion. And here are some more pictures. If you want to see any detail or other angles, just ask. I hope you like it!

I'd bet towards a single M motor: its functions don't appear demanding enough to require L or even XL.

PB1 is the 42010 and PB2 the 42011 (or the other way around). Maybe it wasn't deemed stylish to call the Off-Roader "PB4".

I guess the name is because it's a pull-back car, and that, after this year's two such sets, it's the third.

For you and me and certainly everyone here yes, but TLG also has to consider kids who are just getting started in Technic, the FOLT's of tomorrow.

There should be a picture of it in in this very thread, a few pages ago.

IMO the 42008's looks are great, only tarnished by the fat front tyres, the green 1x3 thin beams sprinkled everywhere, the "missing" micro panels on the side slopes, and the lack of extra black cylinder panels underneath those on the sides. As for the 42024, I don't appreciate the colour scheme: three primary colours is too BOLOCs for me. Then again, I must see and feel more of it to have a consolidated opinion.

And you're right: the major set of 2014 (at least the first half) is the cargo plane.

The rims are the same as on the 8109 and the 42008, but the tyres are new, with a larger diameter.

No, the only image was the same rm8 posted here, showing the Cargo Plane.

Very interesting contest! And IMO the part number range hits the sweet spot between allowing for interesting models and vehicles, and not needing to be a LEGO millionaire to enter. But, due to time, unfortunately I won't be able to participate. Good luck to all! But that would be invalid anyway, since it was (kinda) presented before. That post made my day! But be careful: it refers to a competitor...

I got the solution! My problem was that I was missing the update flags on SetOutput, which commit the changes. By using OnFwdReg, all required parametres were set automatically. Here is John Hansen's explanation. Anyway, I found out by experimentation that MotorOverload takes a while to conclude that the motor is stalled (it increases the motor power to try to overcome the limit until it gives up), so I checked instead if MotorActualSpeed (the power applied to the motor) was greater than 75%, and it worked. if(abs(MotorActualSpeed(OUT_C)) > 75) { Off(OUT_C); stall_C = sign(MotorActualSpeed(OUT_C)); //Won't try moving in this direction next time } kieran, there's no need to manually do that: that's (if I'm not mistaken) the purpose of the MotorTurnRatio function. ;)

Of course! Even if a reply isn't a solution, it may lead to a solution or inspire a solution.

Yes, that's what I'm doing. The problem is that, if I use the first piece of code instead of the normal "OnFwd", the motor doesn't start... if I do use "OnFwd" and the second piece of code, the motor doesn't stop. Anyway, I followed Conchas' suggestion and posted the question at Mindboards.

What language did you use for that code? It doesn't have the structure of NXC, and I couldn't find any NXC function named "motorlimit".

Exclusive sneak peek at the sets and some new parts for 2014, on TechnicBRICKs: http://www.technicbr...ak-preview.html

Hi all! I'm programming a robot that has limited travel on one of its articulations. I don't require precision on its position, just that it stops the motor as soon as it hits the limit. NXC has the MotorOverLoad function, which appears to do exactly what I want... however, it always returns "false" even if the motor is completely stalled! Digging a bit, I found that MotorOverload is actually a shortcut for one of the fields of GetOutput (like "GetOutput(OUT_A, OverloadField)"). Checking the field's documentation, I see that, for it to work, I need to set the motor according to numerous parametres... but, after setting them, I can't get the motor to actually run! This is what I wrote to get the motor running, while enabling MotorOverload: SetOutput( OUT_C, RunStateField, OUT_RUNSTATE_RUNNING, OutputModeField, OUT_MODE_MOTORON + OUT_MODE_REGULATED, RegModeField, OUT_REGMODE_SPEED, PowerField, power_C * d); (power_C and d are variables I defined) If I use the normal "OnFwd" instead, the motor is never stopped: if(MotorOverload(OUT_C)) { Stop(OUT_C); } What could I be doing wrong? Thanks in advance!

I wouldn't buy any more LEGO Technic if I were you.

It would be very nice it TLG reused the 9396's tail rotor blades on this small model, to increase availability of the part and to take advantage of an already existing mould.

The Portuguese Technic page has 21 sets listed, including the 41999 (obviously marked as sold out) and the 8110. The PF page has 15 items: the usual components, none of the new ones that came with the Crawlers.

S@H's servers must be overloaded by the combined demand for the DeLorean, and also for the Limited Edition Crawler... I don't think it was very wise of TLG to make those two sets available at the same time.

The price varies: for example, for Portugal it's €39.99

As you can see at the Eurobricks review, it would be very, very hard:

You most certainly got the European box version, which has a lot less writing on it. The North American boxes have to have everything in three languages (English, French and Spanish).
