Programming nxt with ev3 software

If someone makes them both negative they probably want negative rotation. You can also think of it as multiplying two numerical values, giving positive when you take two negative inputs. Great forum! I am trying to control the two large motors and two NXT motors from the EV3 brick using two subroutines. Any suggestions?

Could be to do with how it controls the motors — if possible, use unregulated motor blocks for the NXT motors and use a wait until rotations block to control distance. Use the current power mode to check it is going fast enough, and stop it with a motor: off block. Based on what you have written here, it should not be a problem to have the whole class working off the EVO software, even though most students are using the NXT bricks.

I have found the NXT-G software frustrating at times, especially the interface for connecting variables between the hubs. Is this experience any less frustrating with the EVO software? Dear Laurens, nice article! Maybe the EV3 sensor could be set as a third-part sensor with a specific driver to obtain a retro-compatibility.

I look forward an answer from you. Best regards, Kowalski Italy. I mention a few here. No, but the ev3 software can be usedto program the nxt which csn be bownloaded for free from legos website.

Can a Samantha Module be used with EV3?? You can use a wireless USB network adapter for it — search around. Two questions, firstly does the EV3 workwith RobotC yet and if so which version? Second, Does anyone know if you can use RobotC to operate a joystick of some sort through bluetooth? I have 10 NXT kits to use with my students and no computers. I have access to iPads can they be used to program the brick.? Do I need any adapters or apps? Is anyone using RobotC?

Also is RobotC available for EV3 yet? If so what version? Our experience with EV3 was not that great last year tournament. We had lot of issue besides the brick froze in the middle of the tournament. I have also got both Ev3 and nxt bricks. I have defintiely had issues with the ev3 in preparing for robocup competition events this year.

This could be my liited programming, but they seem to react differently to the same programming. I have been given vi files from the nxt system.

I am new to using the Lego robots and can use all the help I can get. Thank you. You should be able to remake the program easily with a little experience in the new software. The only difference is that some options are removed in the new environment e.

It a good and subscriptiv page you made, Mr. Very Impressiv! My questions are: — Is the Mindstorm EV3 also in though for Adults or are there more the kids involved? The Mindstorms sets are aimed at children building and basic programming and adults building, basic programming, advanced programming, even hacking are all recommended by LEGO , but work best with children who can or likely to be able use computers very confidently, program and think logically.

Normally this means over about They may, all of a sudden, go back to it — just get the set out yourself, do some advanced stuff with it, let them teach you, do whatever. The home set is easier to acquire and has more models available for it online and in books. The education set is better for teachers because it includes lesson ideas e. I would recommend the home set for home, and the education for schools and clubs.

Hi guys, I would appreciate some feedback from anyone who has used the EV3 fairly extensively. I have found them to be a bit glitchy. I really want to consider this as I need to invest in at least 50 kits over the nextfew years and am wondering which path to take. Is this me or the platform?

Some of those may be problems with the demo programs, rather than the hardware. Further exploration will be required to find the real cause. I know that there are some issues with the LEGO firmware when using third party sensors such as sensors from HiTechnic. The most recent update 1. There is an issue with I2C poling on the earlier firmwares. I have noticed that I2C data will clash or even overwrite other I2C sensors with 1. Even if your sensors are on different ports with different addresses.

It also allows you to put EV3 sensors on a splitter to run them on the same port if you are running out of ports. Did they ever come up with a simple fix for the incompatibility between Mac operating systems and NXT Mindstorms 2.

My Mindstorms software always crashed when I opened it. I found various fixes on the internet. I used a thoroughly kluge one for a while—uninstalling flash player the source of the problem then reinstalling it when needed.

I mucked around with various attempts to use older versions of flash player. One of the questions that arises there—As time goes on, just how old a version will be worth using? There were other suggestions, links, etc. I eventually just started using other computers to which I have access. I downloaded the home version of the EV3 software. It works fine. The NXT software still crashes as soon as I open it.

I could just let things go as they are. However, some of my students, colleagues, associates, etc. Have Lego pulled out of supporting NXT? I have misplaced my 2. Very frustrating. I will start working with students next month and have been told the school has a mix of NXT and EV3. My basic question is if I can handle both with one laptop. Hi, I teach mostly with NXT but also do a little with ev3.

However I have found that since switching from xp to seven, which I delayed until the last possible second that there are definite problems with NXT labview software. Ev3 is a bit glitchy too in certain areas, mostly around imported hitechnic blocks. Both of these issues are with the software itself rather than having them both on the same machines. At the end of the day I go through about students a week and may only get an issue every other month. If you want things to go smoothly, computers are not for you.

Installing both software packages should not be a problem. With windows 8 I have seen that NXT firmware will not upgrade. Keep in mind the EV3 programming environment is compatible with the NXT brick and programming is much easier. The only thing to remember is the display is set up differently.

The lines are reversed and the text has to be resized. Is it possible to build all or most of the models from NXT 2. Adding some more lego technic parts or EV-3 sensors is not a problem, but do EV-3 motors and sensors allow to build exactly the same designs just following the instructions of NXT 2. What are the obstacles, if any? And one of them is replaced by a Medium motor.

The NXT just had three large ones. I will buy an additional big EV3 motor if there is a need, but after I have 3 motors, is it a complicated task to adapt most of lego NXT2 standard robot designs to EV3? Well sure, I have done that for several NXT robots in my book. I basically redesigned it from scratch, although that was mostly because the EV3 set came with very different building elements. Hi Robo, my experience is that every time I try to use the hitechnic Infrared 2 sensor the robot freezes.

Like pull the battery out frozen. I got told through this forum that a new firmware and programme update would probably fix it. Other than that I had physical issues getting four motors to fit inside the size limit allowed under RoboCupJr regulations.

To me having four wheel drive would have been a big advantage, but the physical restrictions limit this. I use EV3-home-edition. My hardware is NXT. The software do not recognize the infrared sensor ultrasonic-cm. Loop frequency in EV3. Since this small box in EV3 Soft is very useful, I want it to show.

So I have to emulate an EV3 touch sensor. When using digital outs you may have to include some pull-ups or pull-downs, until you have set the thing to the right threshold giving you stable operations. I found a surprise here: The input is read out analogue, in port view on the display of EV3 there is a bar graph that is proportional to the voltage applied at pin 6. And at 1,82V it switches the digital reading above the bar graph, without any noticeable hysteresis.

So we got a dumb switch. So I place the output of my Hall sensor device it is a IC actually and gives out digital signals on Pin 6, plus wire and resistor as above. You can decide if you place some resistor in serial by watching the resulting voltages at pin6. A signal is digitally fine when both Voltages for logical 0 and 1 are well away from the 1,82V. Everything works fine but the lightsensor. The lightsensor works fine with the old nxt-software. Thnks a lot, beaken. I have found it is a good practice to keep an extra rechargeable battery available if you are involved in a competition that lasts more than 4 hours.

This seems to be the threshold for LEGO when something really begins to go wrong on the brick. What I mean is when battery power begins to wane on the EV3 the brick begins doing funky things that its not programmed to do.

If someone knows why this is happening or can fix it via firmware please step up an fix it. This one glitch alone can make or break your team in long competitions. Any ideas here?

Or at the very least, the rechargeable battery I used has gone bad. It was the older one. My EV3 set is going to be a birthday present. Anyway, I have a question. Having read various comments, I am beginning to wonder if my old Touch Sensor will function properly with EV3.

I know it was designed for the NXT. Thanks, James. Yes, I think so. I have the NXT brick, sensors, everything, except the software for programming. I can then add a Wait Block so that it moves on when it, for example, detects a wall.

However, when I set it to ON, it just rotates for 1 rotation, and then stops. I am running NXT on my W10 laptop. No problems so far.

Downloading EV3 and will let you know about any problems. Hi JsnLn! Have you used the blue unregulated motor block?

We were always disappointed with the not- precision it can go straight or keep track on a circle with some radius. The result is the error, some factor to it, and put it on top of some base power level for the one motor and subtract it from the same base power level for the other.

The amplifying factor can be increased until the motors begin to stutter, then decrease a good bit to stable operation. Here you have the recipe for some easy PI-control on the relative angular velocity for steering. Our normal cartesian measure of Pythagoras is probably correct, but to calculus heavy. Squaring and rooting around. Does it have a floating point module, the poor thing??? Please report back, for you AndiJsnLn. Lego pushing us away from NXT, sigh. It boots so damn fast. Has no one at lego heard of linux and fast boot modes for EV3?

NXT-Users: Do you have rechargeable batteries? After long frustrating sorting charging-discharging sessions with supermarket rechargeables of low quality I dare to recommend. D: akku-onlinehandel. With BC or successors BC etc. At room temp. I will develop a foil circuit for in-place-charging-and-discharging control of 6NiMh. Other time in the year. No more changing of cells. The steering wheel block even tries to go straight in the usual not-to-precice way, so blocking one wheel the NXT stops the other….

I right now have no installation of the EV3 non-edu free version. Could it be it shows the error there while edu works fine??? I have 3 questions for someone. It looks like it in the manual. I have an NXT and am thinking of trying a EV3 and may want to daisy chain to get more inputs and outputs 2. I just tried to download the latest software to talk to the NXT and my computer says it is not compatible with my software Windows 8. Is there a later version?

Our church is doing space challenge competition and we were giving the NXT with the space challenge kit to practice on but everything I find on line they are using the EV3 and we are having a difficult time with hardware hook ups. So question is will the NXT even work with the space challenge?

NXT robots should work fine for most purposes. I have 12 Robotics Invention System 2. If not, how do I get them running? The software is out of date. Hi, How do I connect a normal sensor one used in arduino and stuff…..

I have a temperature sensor with 3 pins. Someone has offered a nxt 2. My son is about to turn 8. He is very good with building legos, and has done a tiny bit of drag and drop programming. Do you think it would be frustrating to him at this age? I could still get it and he could use it more as he ages, or is it better to buy an Ev3 later? Do I need to format the NXT or do something else to make the program compatible and run? I have imported hi technic color sensor to the EV3 software from the hi- technic site and plugged the htcolor sensor to my ev3.

Moreover, even if a program with color detection could run successfully, there was a problem with the brick. The processor of the brick stayed idle since then and I had to put out the battery in order to end the process. I also tried other programs with htcolor sensor block and the same happened. So, my 18 year old was given Mindstorms NXT some years ago which has been wonderfully educational.

After a break he has come back to it and has asked for a gyro sensor. So I want to know are old gyro sensors still available to buy and if so from where? Also thinking ahead what would be best way of upgrading his set or will he need to start from scratch again? Many thanks. Thanks, Laurens, for this very helpful article. I have a large technic and NXT collection already — if I buy an ev3 brick on its own, will I have everything I need to get started?

Ideally I would like to program in a text based language. Thiis website was… how do you say it? Nice replies in return of this question with real arguments and telling the whole thng on the topic of that.

Figure 3: Complete family of EV3 electronic components not every component is included in each set. Figure 6: Due to different plastic connectors, you cannot use the NXT rechargeable battery on the EV3 brick, or vice versa. This image shows central European wall chargers. Software Compatibility The EV3 brick is programmed with new programming software.

All text and illustrations in this article c Laurens Valk Prev Next. Excellent summary, Laurens! Thanks, Philo! Nothing done yet, but it will come! Thank you for this article, i found it really helpful.

The EV3 software is provide with the home kit? Is it on a DVD? My son now has a parrot jumping sumo and would be nice for the lego robot to have similar capabilities I myself used to be a lego fan so I am excited to sit with my boys and build a nice robot with them. Many Thanks, George.

Thank you both. Safety is a good reason to adapt the design. Great comparison post Laurens love your clear pictures and video. Not to be nitpicky. If he tried to out in all the bricks, this page would be a mile long. Thanx for the info Laurens. Remember you can still use I2C devices as well. The software contains various new blocks, such as array blocks. Unfortunately, no. It will only run natively on Windows and Mac. However, there will be other community based programming environments available for Linux.

What do you think? Nice post Laurens! Many 10x for the answer, Janez. However, developers of alternative programming environments may be able to implement this. Thanks for article! The Home edition set will not be released in August — probably early September.

Thanks in advance. Hopefulle it will be before FLL, we needed it. There are many uses to them. NXT programs will not import into the EV3 software. You can download the home edition of the software for free at LEGO.

What are the software requirements? Will it work on OS X snow leopard? I have posted the requirements just a few comments above this one. Does indonesia will get the home edition set. The software will be for free. Hi Laurens, Great article. Thanks, Ian. Hi Ian, Thank you for your comment.

Do you know yet if the EV3 software will be available as an iPad App? It will be avaible for IOS and Android. No, the EV3 programming software will not be available as mobile apps.

However, there will be some iOS and Android apps that will let you control your robot remotely. Thank you all in advance! Contacting LEGO directly is usually the fastest way to get a free replacement. But what if your NXT has the original firmware? How do you update it to the latest version using the EV3 software? Use the NXT software instead. Nice comparsion.

That is correct. Yes, it can. Good article. Thanks for confirming this, Tim — I had forgotten about this sensor! Tried it, working well. Have fun! Crappy forward compatibility! Is there any other option anybody knows? Does anyone know the kname of the NXT-g compiler? So does anyone know if it will run on an Air? Sorry, meant robot KITS! Are you sure that you let the button pressed for 1 second or so? Try to rule out some possible problems to see what may be going on. There is a known issue with the batteries, but you seem to be describing something different.

I meant processing. How would rate the backwards compatibility of the EV3? Where you able to get bumped 2 to work? I was not. Hi Iwjev, I agree, the whole thing about Compare, Measure and Change has not been a good design choice in my opinion. Excelent post! Thanks a lot Grettings from Peru.

Excellent Summary, Sir. I would say yes! Perhaps even more, considering you can also hack away in the Linux underneath. Thanks a lot!!! Thanks there. That helps. Thank you very much! Yours Andi. Best, Laurens. HI Laurens: I just pre-ordered your book. Hi Sara, The apps allow you to control your robot remotely, but you cannot program it from the app. Thanks, Laurens. If you want to use one programming language for all your robots, just use the free EV3 software.

The IR sensor can do that, and much more: Proximity mode approximate distance to any object Beacon Heading mode direction of the IR signal Beacon Proximity mode approximate distance to the remote Remote mode detects which button on the remote you press The IR distance sensing is less accurate that the ultrasonic distance measurement, but you get a lot more functions instead. Thanks for the prompt and detailed reply; I do appreciate it. Any pointers! Download the block on the Lego website downloads page.

A single EV3 brick would work, but it is relatively expensive to buy separately. Hi David, There is other information in the help section that is incorrect as well. I actually prefer having negative degrees reverse the motor for the reasons you mention. The following situations can cause the direction of the motor to change: a negative angle b negative speed If both situations occur you change direction twice, and therefore you go forward.

Nah, EV3 software is genius. It is much better — especially the data wires. Let me know, also the Volks allready using it! Glitchy or unstable in what way? Really usefull.. Did anyone try that? Regards Gildardo. I want to compete in the Robocup soccer tournament, would the EV3 do the job? Hi there! The Touch Sensor again… EV3 vs. If you need drawings circuits or photos comment here. Hello I have one question. Thanks, JsnLn. I just got hold of a NXT brick and tested.

It keeps moving the free wheel if you block the other. So all fine, one might say. If you still like to try the circle follower, I would be interested to hear from you.

Which firmware does your NXT have? Is the EV3 compatible with the operating system Ubuntu? Hi Laurens, your lego discovery books is awesome.

It helps a lot. I like it only one question Is one better than the other is so how. Both are free. Can I use Ev3 sensors using Nxt using the Bricx program? What is the problem? And what can I do in order to use the htcolor sensor? Thanks Laurens for this overview!
