IR Receiver not working
max777 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi Folks, My son got the Minstorm EV3 for Christmas. So far the basic model that comes with the Mindstorm Box has been built. I think it is called Track3R. The demo program has been executed sucessfully. The thing can move forwrad, backward, rotate, and turn its propeller in both directions. However, we are having some issues with the infrared sensor. The light turns green on the remote, but the IR sensor doesn't receive the signal. I have tried all channels 1, 2, 3, 4. I also did indeed changed the EV3 menu to "IR Control" before activating the IR remote. On the EV3, the screen shows "CH1+2". Then I see an arrow going from CH2 to A then from CH2 to D and then from CH1 to B and C. Am I missing something? Max. -
Mindstorms EV3 and Android Bluetooth
tsukanomon posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello everybody, I am trying to get my mindstorm EV3 to work with my Android 4.1.2, although I cant find any tutorial on internet that can teach me how to do that. Actually, I've been trying to work with Monobrick and Xamarin, but I am experiencing some unknown error when I try to add the DLL's from the "Monobrick for Android" library to my Android Xamarin project. Do you know any library that I can use to communicate my android with my EV3 using the bluetooth ? I am intending to initially communicate via Bluetooth with my EV3, just sending basic commands like go forward, backward, left, right etc. Afterwards I will try to integrate it with OpenCV in order to let the robot see the "outside world". So please if you guyz know anything about communicating android and MindStorm EV3, it would help me A LOT. Thanks. -
Illegal EV3 Education Sets (45544) on European market
peter_m posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I move the discussion from Mindstorms General Discussion thread to get a wider attention I have recently bought two EV3 Education sets (45544) on allegro.pl, Polish analogue of eBay - from unofficial seller. It turned out that the sets did not contain the rechargeable batteries - instead in each box there was a notice from TLG saying that they have found an error in circuit and removed the battery from all of the sets. And that they will provide it later... I have called Lego support and the Support Lady said that they got some similar complaints already and that they are trying to solve this situation - I was asked to call in 2 weeks time. So I did - and I got an information that those sets (with notice instead of battery) were not supposed to appear on Polish or even on European market - and that they will not provide batteries to those sets. Now I ask you my dear Eurobrickers - what do you think about this situation? It is clear to me that TLGs distribution chain is malfunctioning - and I feel a little bit cheated - as I am the one (among many) that suffers. -
EV3 IR Beacon (remote) and PF IR Remote
le60head posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hello! Recently i discovered that both the Mindstorms EV3 beacon and the PF IR Remote are interchangeable. Here are some explanations: I was very happy to know that the EV3 Retail Kit comes with a Infrared remote(beacon), which can be used as a remote control for your robots. That's pretty handy if you want to build robots that interact with humans. By accident, i found out that the IR Beacon and PF remote are interchangeable for use with both the MS EV3 and PF systems! I tried it, and they both work with the Mindstorms EV3 IR Sensor and the Power Functions IR Receiver! Seems that the IR signals they produce are the same ( escept for the beacon mode button on the Mindstorms remote). The conclusion is that they can both be used to control EV3 and Power Functions models. Some time ago i read that the RCX can be used to SEND IR signals to the PF IR Receiver. That probably takes more knowledge than i currently have. This lead me to the following question: Can the Mindstorms EV3 Sensor can do the same? Is it able to send IR messages to other devices? For example, is it possible for an EV3 robot, using the Infrared Sensor, to send signals to a Power Functions IR Receiver? In this way you can expand the motor limit (4) with an external battery pack and an IR Receiver. I hope someone has information on that matter! (Solved! the EV3 IR sensor cannot be used to send IR signals to PF receivers and such ...) Thank you in advance! -
Browsing through some pictures mentioned in [MOC] Dodge Challenger '70 R/T (by Dustyen055), I continued to browse and found this nice creation. More photos can be found on Flickr Chronicler35 -
I like your projects!! Unfortunately creating a topic on EB to promote your own Blog is not allowed, so I have moved this post to the Mindstorms MOCs and Models topic.

EV3ed 42006 Excavator
dwalton76 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I recently combined an EV3 with a 42006 Excavator to make it fully remote controllabe. I put together a video of it in action: Here is a blog post I did on it with links to the instructions and EV3 code: http://programmablebrick.blogspot.com/2013/09/remote-controlled-ev3-lego-excavator.html It was a lot of fun but figuring out how to build a motor multiplexer small enough to fit in there was tough. -
EV3 Brick too slow...
alfredone78 posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Hi all!!! When I turn on the EV3 Brick, it takes too much time to start up!!! And the same in order to turn off it...! Is it normal? How many seconds does your EV3 Brick take to turn on and turn off? Thank you! Regards, alfredone78 -
