Esben Kolind Posted February 28, 2013 Posted February 28, 2013 Hi, At the recent Lego World 2013 in Copenhagen I displayed my model of Islands Brygge Metro Station including NXT controlled sliding platform doors. This model is the fourth in a line of trains with automatic sliding doors, that I have built over the last years (version 1, version 2, version 3). I have compiled a short video to show all the functionality including some "behind the scenes" footage: The NXT controls the following: Output 1: Running the train on the inner loop (9V) Output 2: Running the opening mechanism for the three sets of platform doors and three stes of train doors Output 3: Running the elevator Light sensor: Stopping the train at the platform (accuracy: 1 stud) Distance sensor: Detecting the lower position of the elevator (dynamically calibrating the elevator cycle) Touch sensor: Detecting the outer position of the opening mechanism (dynamically calibrating the cycle) In addition, there is a 9V metro train running on the outer loop and PF lights on the platform wall and over the platform door. Some images of the station, which was part of a bigger display of Islands Brygge, a central neighborhood in Copenhagen: After moderation, more pictures can be found here. The station is modelled very closely after my local metro station, though I have reduced the number of opening doors to three sets. Here are some reference pictures: I am looking forward to your comments. Esben Quote
Selander Posted February 28, 2013 Posted February 28, 2013 Absolutly amazing functionality, Esben. Quote
LEGO Train 12 Volts Posted February 28, 2013 Posted February 28, 2013 Stunning opening system! I love to see this kind of technical features! Amazing and neat layout! Quote
Werlu Ulcur Posted February 28, 2013 Posted February 28, 2013 I'm speechless! That is awesome to the Nth degree! Quote
Duq Posted February 28, 2013 Posted February 28, 2013 I saw the title of the topic and knew it had to be Esben. Well done! Very clever mechanisms and very well executed. Quote
eurotrash Posted February 28, 2013 Posted February 28, 2013 Fantastic Job! Thanks for sharing it with us! Quote
kieran Posted February 28, 2013 Posted February 28, 2013 Trains and NXT, 2 things very close to me, what a wonderful use of the technology, really looks the part, well done Quote
bricks n bolts Posted February 28, 2013 Posted February 28, 2013 Wonderful creation and mechanism. Thanks for sharing the 'behind the scenes' footage. Quote
Pop Bumper Pete Posted March 2, 2013 Posted March 2, 2013 I am amazed at what people are doing with Lego Quote
Zed_43 Posted March 2, 2013 Posted March 2, 2013 WOW!!! Amazing!!!! I have always wanted to build somtehing like that but the mecanics are not my stuff... You've done it like a real engineer! Congratulations!!!!!! Quote
zephyr1934 Posted March 3, 2013 Posted March 3, 2013 Fantastic details (both in the model and in the movie) and a great build Quote
Wedge09 Posted March 4, 2013 Posted March 4, 2013 Awesome work :thumbup: Full of detailes and the doors open system is really interessant Quote
Hrw-Amen Posted March 4, 2013 Posted March 4, 2013 Wonderful detail. I only wish I knew this much about technic stuff and NXT to be able to use it in my builds. Quote
Locomotive Annie Posted March 5, 2013 Posted March 5, 2013 (edited) Jaw droppingly brilliant! An amazing technical achievement; - now all that needs to be done is to devise a way to actually get the minifigs to board the train. And I must say that the city street above the station is really great too. Edited March 5, 2013 by Locomotive Annie Quote
harnbak Posted March 5, 2013 Posted March 5, 2013 oooh noooo - now I will never forgive myself for not going to Lego World this year... this is mindblowing - absolutely lovely how you flawlessly combined multiple disciplines in this fantastic model! Quote
L@go Posted March 5, 2013 Posted March 5, 2013 This is great - especially as it shows what kind of technical ingeniuity you need to get such small and "simple" details to actually work. You have my deepest respect for what you manage to do with your trains. On another note: I can't believe I missed this in Copenhagen! I thought I saw everything there, but never noticed this. My loss... Quote
mikezang Posted September 13, 2013 Posted September 13, 2013 That is great! By the way, I want to know why don't you use PF train instead 9V train? Is it difficult to control? I had used 4 RCXs to control two 9V trains and one car past, you can view it now I want to control PF trains with NXT or EV3, but I have no idea to use NXT controlling PF trains, do you have any suggestion?

rriggs Posted September 13, 2013 Posted September 13, 2013 Brilliant! So simple yet so effective. Good job Cheers Rog Quote
JopieK Posted September 14, 2013 Posted September 14, 2013 @mikezang, welcome to Train Tech and EB. Maybe you could introduce yourself first. It would be a good idea to start a new topic on remote controlling trains using EV3 and older mindstorms versions, but I think it would be better to create a new topic for that. @rrigs: simple solutions are often the best :) Quote
