[EV3] [HELP] Patrol Dog
Doc_Brown posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
I was just wondering how hard it would be to implement an idea I had for a EV3 moc. Basically I want to create a patrol dog model and its functions include the following. -Search and establish territory perimeter (living room) -Randomly patrol in the area -Return to Red water bowl occasionally -Return to Blue dog box to rest occasionally. ( when battery gets low, with a unique bark to let owner know) -Bark at any loud sounds (if possible) I'm not sure what the minimum of sensors would be required to perform such tasks, or if all the above is possible. Any advice would be very welcome. Also are the NXT motors and sensors are compatible with the EV3 block? Thanks! -
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! -
SL3IGH: a Christmas robot
AVCampos posted a topic in LEGO Technic, Mindstorms, Model Team and Scale Modeling
Here is something I built for the MCP Program, using exclusively parts from set 31313: This is Santa Claus' sleigh, pulled by his faithful reindeer Rudolph! Rudolph pulls the sleigh by using the same leg mechanism I came up with for : a simplified version of the Klann linkage. Besides the large motor for walking, there's another one for (very roughly) adjust the angle between Rudolph and the sleigh to allow for curves, and a medium one for making Santa wave his arm.Of course, Rudolph has to have a red nose! The colour sensor, set for reflection mode, gives the nice redness. Like with , I made a point of using the infrared sensor "upside down" for Santa's eyes, to avoid the "aggressive" look given by the lines printed on the sensor. I tried to have the EV3 prominently displayed, with its side ports for USB and SD unobstructed, and reserved space for the rechargeable battery.I really like how the robot turned out to look: it was fun trying to make the most of the 31313's relatively limited assortment of parts (for example, some dampers for Rudolph's hooves would be most welcome). On the other hand, I really wasn't able to make it work well: with an EV3 loaded with batteries, a large motor, a medium motor, and assorted parts, the sleigh got really heavy for Rudolph to pull, even with wheels underneath. Also, the steering is just too abrupt for direct remote control, and I couldn't find a way to gear it down while using the available parts and still look cool. Here is the video of it in motion. And here are some more pictures. If you want to see any detail or other angles, just ask. I hope you like it! -
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. -
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 -
