Brick: Drive to first position (using Mindstorms sensors and motors) Brick: Tell phone "do your magic" Phone: Make a picture, scan QR code etc Phone: Tell brick to stop or proceed Loop this until the right code has been found. Looking forward to seeing this in action!!

Using just the light sensor, you are probably right. Using extra hardware like a phone, it's possible.

To answer your question; yes it's possible. The actual solution depends on how you connect your phone to your brick. Do you want to let the phone do the thinking (recognizing the right bar code etc) and just sending a "No, not this one" command to the brick. Or do you want to do the processing on the brick. Lot's of options.

Having a USB port, I think the EV3 will support webcams and other cams better than NXT. Maybe you are better of using QRCodes, or does it have to be a barcode?

LeJos has some pretty good things. I really like the "sensor call back functions", which provide sensor feedback in a very nice way. Maybe I will start using LeJos again, although RobotC is great as well.

You could take a look at the Mindstorms Index under Programming Environments. I would recommend, BricxCC, LeJos or RobotC, depending on your skills. All three do rely on basic programming skills, so they are not graphical. You could also try Microsoft's Robotic Studio, which is more graphical if I am not mistaken.

Dude!! Fantastic. I will definitely visit you if I am in England some time

Are there any parts some of you are particularly interested in? I might add those to my order. Hehe. As usual, more talk than building Off topic: I have a Wall-EV3 with Wheels WIP, which I will hope to have working by the end of this month. I am very busy with other stuff as well, so I lack some time. On topic: I could already send you two of these! If you are interested PM me.

If the costs for sending an envelope to Australia aren't that high, I could send them to you after reviewing them. If Border Security will let them through

Let me know what you are interested in, so I can see what I can do. It's working! Shall I try Premium Silver for 68 euros?

"Sorry, you don't have permission to perform this action." Guess it's still not public.

Okay, for the time being we will let this topic evolve and see what happens. I have included a short description in the first post, explaining how to ask a proper question. If there is something missing, please let me know. Of course it's not forbidden to start a separate topic if you feel that your problem needs it.

That's why I suggested to try out more parts The shipping will probably remain the same. I can try them for you, which will be cheaper. But you need to rely on my review Do you have a link to your part?

I've also got version 8 Nope! Just the parts I linked earlier.

I agree that the topic in this form might not be the best solution. Let me consult with some regulators and moderators to see what's the best course of action. Having an index in the first post is a nice idea, but the answers will still be given in the middle of other questions etc. Not ideal either. I also agree that a certain format for a question might be useful....especially including a picture. To be continued...

Based on the material. It's fine to use a part with technical function, like some sort of pin. But I am not sure about using it as a liftarm.

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. Line following NXTPrograms.com Line Follower (NXT-G) PID Controller Tip! Great tutorial on PID controllers (Pseudo)

I am going to implement the PID controller (most likely only PI) for rotating my robot, using a HiTechnic compass sensor. I will do this in EV3-G (don't even know the real name) and RobotC when it's released.

Funny that you mention this, because custom rims was the reason I tried Shapeways in the first place. I would also like to have different rims.

You probably mean this link: http://www.inpharmix.com/jps/PID_Controller_For_Lego_Mindstorms_Robots.html Have been reading it as well. Awesome tutorial!

It's not cheap but if you are mildly interested in electronics, programming, robotics, etc, you will have loads of fun! And the new motors are way better than the NXT ones. So...do it! Off topic: how about uploading a profile pic?

HELP WITH YOUR MOC This is a topic where you can ask other members for help with your MOC. It's linked in the Technic and Model Team Index. GUIDELINES FOR ASKING A QUESTION AND POSTING AN ANSWER Description Please be as clear as possible describing your problem. Reread your question and ask yourself whether someone without prior knowledge will understand your question. Picture A picture is worth a thousand words. Please try to include a picture with your question. This will make things more clear for other members. Tip! If you don't have storage online for storing a picture, please checkout Bricksafe. It's a great site for sharing pictures of your Lego creation. Alternatives are Brickshelf, but it will take some time before your pictures will be visible to other users and Flickr, which is pretty self explanatory. Remember to deeplink an image with a normal resolution, like 800x600. Whatever you do, don't post images that are over 1024x768 pixels (or 768x1024 pixels for pictures with a portrait orientation), which is stated in the site guidelines. Posting an answer When posting an answer to a question, please make sure to add the name of the member to whom to you are replying. Even better would be quoting one of his/her posts. When quoting a member please remove the images from the quote, unless it's really necessary to include them.

Looking forward to seeing you more often in this topic

I guess you are using Android. Haven't got any experience with that. Have you read some of the previous pages in this topic?

I don't think you will be very pleased with that part, but still, you should give it a try! When ordering, I would add some other parts as well. It's not that expensive and you have to pay for shipping anyway. Something in the GoPro section would be cool for my EV3....hmmm http://www.shapeways.com/model/1302185/gopro-to-lego-beam-camera-mount.html?li=search-results&materialId=6
