[EV3] Technic Jim's Mindstorms EV3 Thread
Technic Jim posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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.

[Mindstorms] NXT with leJos spewing garbage on screen
MikroMan posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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. -
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 -
LEGO Mindstorms Programming General Discussion 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.

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

Mindstorms EV3 for kids question
JGW3000 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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! -
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?

Trouble with nxt programming
KDM posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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. -
NXC: MotorOverload always returns false
AVCampos posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
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!
