  1. The Delivery Station unloads the train, separates the candies from the containers and delivers the candies to the visitors. The 2017 consisted of four parts: Push mechanism: pushes the containers-with-candies from the train Roller mechanism: rolles the containers-with-candies to the lifts Lift mechanism: lifts the containers to separate the candies from the containers Locker mechanism: candies are stored in lockers, to be opened with the ticket reader The order of the candies needed to be kept, so every visitor received the candy in the color he requested. You can watch the 2017 here (starts at timestamp 2m39s): For 2018, we keep the Push mechanism and the lockers. The part that will take care of separating the candies from the containers, is completely redesigned. The push mechanism however, was rather slow and - as you can see in the video - it needed quite some space due to the slider. So, that needed a redesign as well. You can see the new version here (click on the photo to go to our Flickr page): And of course a video: Enjoy, Hans
  2. are there here users of ev3basic here ? i m a great fan of basic [ i use it +-33y ] the only problem is that in smal basic the char's of the IDE can not be bigger i got the following working test.sb : a = Buttons.Current EV3.SetLEDColor( "ORANGE" , "PULSE" ) While a <> "U" a = Buttons.Current EV3.SetLEDColor( "GREEN" , "NORMAL" ) Program.Delay( 500 ) EV3.SetLEDColor( "RED" , "NORMAL" ) Program.Delay( 500 ) EndWhile EV3.SetLEDColor( "ORANGE" , "PULSE" )
  3. Hello everybody. Recently i found a segway program on ntx with extension .rbt. I need to convert it into .ev3.I tried, but it didin't work. Who can help me? If it is not hard for you, plz email me: alexander.gavura@gmail.com.
  4. The last years, we have used a NXT brick for controlling the train. For Lego World 2017, we want to use EV3 bricks only. Since the RFID sensor is not supported anymore, we needed another way to determine the train location. I have build a proof of concept of a loco: Wheels are directly connected to a EV3 medium motor Location detection based on a color sensor (the combination of yellow, red and green makes a unique pattern) And it works fine! A video of this proof of concept: Of course, the train needs a bit (... ) of restyling ;-) Enjoy, Hans
  5. Hi all, since I recieved Mindstorms EV3 set 31313 few days ago I've decided to start my first project. I call it CLEV3R CAR and as you can guess it's about car. I've just finished building it and I'm about to start programming it. So let's talk about model first. It looks like Mini Cooper, chassis is inspired by RAC3 TRUCK and I've finished it in just two days. It features two large motors for driving, medium motor for steering, IR sensor instead of radiator and rear bumper with touch sensor. I wanted to build it as small as possible but it became pretty big. I've paid attention to many details so you can easily remove EV3 brick (for example to change batteries) and there is enough space under it so you can use it with original rechargable battery as well. It's also pretty sturdy, I plan to program several modes for it: Automatic - independent driving with avoiding obstacles RC - remotely controlled from IR beacon with driving assistance (for example if you drive it against wall it will stop before it) Search for beacon - independent driving to beacon By the way does anyone have experience with programming searching for beacon? I can imagine how to do it for tank (or other tracked vehicle that can turn on the spot) but car with classic steering is something different...
  6. Not really, but I found out that the motors in my GX EV3 peform better in IR Control mode than how they do in my program, and I believe that it is because the motor power is different. Each block in the EV3 programming software that moves the motors has a digit for how much power each motor should have. I'm wondering what this digit is in IR Control mode, because the motors act much better in this mode than how the do in the program. If anyone here knows the power of the motors when the EV3 brick is in this mode, please reply as soon as possible. It would be very appreciated.
  7. Hello friends, It is I, elrid from india, and I am of having difficulty sending sounds over bluetooth to a second NXT. I have a master-slave relationship between two of my best NXT specimens, but one of them does not have working speakers (even the startup noise doesn't work my friends!!!). So, I am of trying to get the first NXT to signal one of another NXT with speakers work over bluetooth connect. I use BrickxCC language. Any help is appreciate. Thank you friends! I am see with my eyes there is individual named DR_SPOCK who is very helpful and handsome. Hopefully he can help.
  8. I wanted to tell you about this new (and cool if I may say) program that is being developed by a company with more than 30 years of experience in robotics for education called Intelitek. This program, called CoderZ, is all about teaching kids STEM through robotics and programming. This program enables an entire team to have a robot for each participant/member. How? Well, CoderZ is a fully operational robot simulator. Right now, Intelitek is giving FLL teams a free trial that lasts until the end of June, this is a great opportunity for all teams to hone their developing skills for next year’s challenge. You can easily register and start using CoderZ by clicking here: bit.ly/2pq0LnA Feel free to share your thoughts with the CoderZ team after registering and trying it out at http://gocoderz.com/.
  9. For our Sioux.NET on Track project (see https://siouxnetontrack.wordpress.com), we not only write a PC application in Microsoft.NET (C#). But we also write quite some code that runs on the EV3 bricks. In this article, you'll find programming tips & tricks for the Lego Mindstorms EV3 programming environment. Is it possible to have two or more EV3’s in Daisy Chain mode and use WiFi to connect to the PC application? Yes, you can. Read the full article how you can achieve this at the blog: https://siouxnetontrack.wordpress.com/2017/04/08/how-to-ev3s-in-daisy-chain-mode-plus-wifi You can use two or more threads in parallel to run on an EV3. But how do you synchonize them? Read the article how to do this at the blog: https://siouxnetontrack.wordpress.com/2017/04/02/how-to-synchronizing-two-threads/ More to come later. Enjoy, Hans (moderator of our Wordpress blog Sioux.NET on Track)
  10. Hi ! Some students and me create a new exercise for other students. This time we constructed a robot using mecanum wheels. Students should learn how to control this robot using mathematical equations and implement them in Java leJOS. Have fun! Andreas
  11. Hello fellow train builders, I would like to share my most recent project theme; Lego Trains & Internet of Things. Basically, I make connected trains and train related stuff. My aim is not to be 100% realistic or copy existing real world trains. My goal is to bring Lego into the IoT movement, learn many great things along the way, and eventually help the next generations to get interested and pick up the necessary skills for a better world through technology. Let's call this STEM through Play.(STEM=science, technology, engineering, and mathematics. Sounds like a mouthful, huh? but that's what I want anyway ) Without further ado, here's what I have built so far; Automated Lego Railroad Crossing Lego Train Voice Controlled Lights via Amazon Echo Lego Train Controller App Please bear in mind that this project is new and under development. I welcome any sort of feedback and questions I will also update this thread but if you'd like to keep up, here's my website which aggregates all the social channels related to this project: Legongineer
  12. Sioux.NET on Track presents the Ticket Dispenser Unit (TDU) Two articles about the Lego Dispenser Unit can be found at our blog: https://siouxnetontrack.wordpress.com/2016/09/28/ticket-dispenser-unit-reader/ In this article you can read how tickets are read using a four-color based number system. This article was written before the dispenser part was created, so it is only about the reader part. https://siouxnetontrack.wordpress.com/2016/12/28/ticket-dispenser-unit-complete-version-2017/ In this article you can read about the upgraded version that will be used at Lego World 2017. Click on the following picture to see more pictures: A video of the working TDU 2017 can be found here:

  14. I am new to this blog and don't know how things work yet. I have a few questions about some programming I am having trouble with and wanted to see if the community can provide me with some programs they've built. 1. I want a program so that you can press the touch sensor ex. 2 times, it would run the 2nd program; press the touch sensor 4 times it would run the forth program etc. Or have a color sensor and I put a red brick in front of it and it runs a specific program. 2. I have a wall follower program and I am wondering if it can follow the wall for about 24in or so and then stop and do some other action. Does anyone have an idea on how to do this, and can you provide a program? I can't figure out how to program these. Any tips, programs, would help!
  15. Hello all! It has been a while since I have posted here but I have got a new toy! It is on loan to me for the summer and I plan to use it well. This thread will be where I post all my creations and hopefully the programs. I have a few programs ready and waiting to be filmed and a lot more ideas. None of them have been filmed yet, but here is a trailer to wet your appetite!: As usual, please leave any constructive feedback and keep popping back because I will (probably should!) be updating this thread fairly often.

  16. I've been testing leJos with my old NXT brick and something seems to be wrong.When I flash the brick with latest leJos firmware, it works fine. After some time, it starts spewing some garbage onscreen: The only thing I can do is press Off button, but then it doesn't boot up again and I need to try multiple leJos/official firmware reflashes to get it to work. Has anyone encountered anything like that? Any help would be greatly appreciated.
  17. At our Youtube channel, you'll find a video of our fully automated train layout. It will be displayed on Lego World Utrecht 2015 from October 25 (Sunday) until October 27 (Tuesday). The video shows the layout in our test room. The train layout contains eight EV3 bricks and one NXT brick to control all the Lego objects. The layout is controlled by a PC application (Microsoft.NET) that has been written by our team. Enjoy the video and maybe we'll meet in Utrecht. /Hans
  18. Mindstorms Programming Welcome to the Mindstorms Programming topic. If you have any interesting information, tips, links or questions, put them here. I will update the Index of this post when new content is available. After every topic I will describe which programming environment is used. For a detailed list of the most popular programming environments refer to the Mindstorms Index. The software TLG includes with the retail kit and can be bought separately for the education kit is called EV3-G or X3. I will use the term EV3-G from now on. Pseudo means it's not specific for a certain programming environment. Is a generic article with coding examples and/or principles which apply to most environments. Line following NXTPrograms.com Line Follower (NXT-G) PID Controller Tip! Great tutorial on PID controllers (Pseudo)
  19. Background With some colleagues of mine, I am working on a fully automated train layout. You can read more about this at our blog: siouxnetontrack.wordpress.com. The layout is always demonstrated on Lego World in Utrecht. We gave a demo at another event, as can be seen on the following Youtube video. One of the items I have been working on, is the Candy Rotation Stock. I made a working version, as can be seen on the next video: Redesign of the Candy Rotation Stock After building the final version of the Candy Rotation Stock, I transported the object to our office to integrate it with the other parts of the track. I found out that the CRS was not robust enough and it took some time before it worked again. Although the concept works, it was not good enough to run for a couple of minutes without problems. And I needed it to work for four days at Lego World! So I took the difficult decision to redesign it. In this thread you can follow the progress. The redesign will be based on the conveyor belt that I found on Youtube (user ssugawara1955): And this is my proof of concept: I have ordered some extra parts to make a complete square and two switch points: one switch point that will lead to the Crane Pickup location and one switch point where new containers can be inserted to the rotation stock. Some more photos of the progress can be viewed on flickr: https://flic.kr/s/aHsk8h6MAc . Enjoy. /Hans
  20. Hey guys, I am serious considering getting the EV3 set for my kids, so they can learn a bit about robotics and coding - they are 10 and 7, so should be age appropriate. I am not at all familiar with the EV3, so hopefully someone can answer these questions. Can a Win 8/Win 10 PC be used to program the control brick? Will an old smart phone (deactivated) be useful for bluetooth control? Will this actually be a good introduction to coding? Aside from the EV3 set, should I get additional sensors or motors - we have plenty of bricks and technic parts already, of course. thanks!

    Automated Layout

    Hello, I am woking on plans for a Lego layout of the majority of the Magic Kingdom, in Walt Disney World Florida. I am planning on using the Philips Hue System for lighting so that I can have daytime/nighttime/morning/evening. I also am going to include LifeLites for the lighting of the street and in buildings. A few of the rides will be able to run as well, including the Walt Disney World Railroad which runs around the park. Lastly I am also going to include sounds into different areas of the park to add to the realism. Is there a program where I can make all these systems automated so that by the push of a button or two the entire layout comes to life?

  23. I'm a beginner at nxt programming. I built a train drawbridge for my lego city. I thought, I would try and use the nxt technology to make the bridge go up and down as the train crossed over the bridge. I put a pressure switch at each end of the bridge. One to tell the bridge to go up and one to tell the bridge to go down. It seems so simple but has become so frustrating. If train comes from one direction each time no problem. But if the train comes from the other direction the commands get confused. I did two series of commands, each by themselves work just fine. If I put them together, since I'm using the same switches, the program gets confused. I hope someone can help me with my problem.
  24. 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!
