Lego Mindstorm Download

[Varinia Swicegood]

LastSunday, despite the very nice weather (actually even way too hot for Hamburg) we decided to stay home and have a "rest day" ( we are a really active family always engaged in physycal activity, be it climbing, cycling, trekking).

My kids just got a Lego Mindstorm EV3 set as a joint birthday present ( that thing is quite expensive - worth it, but still expensive) and we decided to build it all together.

To make it special, and to remember this epic moment - the first lego Mindstorm ever ( my kids are probably a bit underage for that kind of thing, being 8 and 11) and to add some additional learning activity to it - we decided to record the entire building session and make a time-lapse video out of it.

We often make photobooks and short movies out of our vacation footage and I always involve my kids into the editing process (so that they can slowly get into tech and tools by making things and having fun, - more on this in a post to come), but this time I had no idea how to make a time-lapse, so we googled together to find out how to set up our camera and we did the math to define how many shots were required.

We did not want to spend too much time in learning how to make a time-lapse and install the necessary software on our Reflex, therefore, this time we opted for our cheap GoPro alternative which already comes with a handy time-lapse feature. Unfortunately, the available range was either 1 or 2 seconds ( or more ) so we set up 2 seconds. Worst that could happen the final video would be shorter.

Then we downloaded the instructions on the phone and started building.

With up and downs, some moments of stress (the little one crying because he was a bit frustrated by the complexity of the project, and the bigger one arguing with the mother because he was rushing and skipping some steps - that caused unmounting and rebuilding of some parts), just a couple of breaks for the toilet and a few minutes to cook some sandwiches we took 3 hours and a half from the opening of the package to the remotely controlled working robot.

We decided to keep the programming part for another day and after having played a bit with the robot we quickly edited the video with iMovie, we picked some suitable music and speeded up some parts (we found out that our calculations were wrong - the video was almost 30 minutes long! - probably the framerate set on the camera was different - I did not have time to check it yet. Any idea? ), then we could finally watch over and over the recording of our achievement.

I find this kind of activities very rewarding - you spend time together, building something, learning new things and you end up with a nice funny memory. I guess this will be just the first of many other time-lapse videos!

Thanx. Next we will definitely start to play around with the programming side of EV3 - at first with the native - blocks - scratchlike language, and then maybe with something more "scripted" ( need to check out about nodejs )

My friend and I are building an app that allows you to control the motors on a lego Mindstorm (ev3). However, when testing we have been given 2 error codes (516, 517) which translate to the Bluetooth not being able to read and write the connection. We were also given error 3102 - Unable to receive a reply or the reply cannot be understood.

Yes, we have connected via smartphone settings and paired the two devices. There is a section within the app to select the Bluetooth device which is where the errors present themselves, after selecting the EV3.

I know cause I also made a small app for my EV3. For example if ev3 is not present (turned on) you should have received an error 507 unable to connect. Does your EV3 connects to pc ? Can you send program via bluetooth?

Here there is an assumption that the connection is made, but you need to confirm the connection first, using a Clock Timer, and assign the Bluetooth Client to Ev3. Something like this (untested, I have no Lego )

Apologies for the inactivity (exam week)! Thank you so much for the solutions. Unfortunately, my class has run out of time for building the app and I won't be able to test your theories. From what my partner said (she tried these methods while I was away for a school camp) the code you provided solved the problem however we received a Bluetooth property error. I'm pretty sure that is because the 'BlutoothClient1' wasn't selected in component properties but I won't be able to test that theory.

I had camp last week and I had a challenge to build this sorter. I built it and downloaded the mindstorms programmer to my computer. It comes with all the programs to all of the listed builds. If may be a little confusin but it is manageable.

Hey Laurens! Can you upload the program for H25? If you dont have the program, can u pls give me the opportunity to create a post, cuz i have the H25 program, i programmed it with the program turtorial from the education site. Im ten years old, almost eleven ?

Hi,

Thanks for the PDFs. Indeed, my pupils want to build the four Robot models of the EV3 core set.

Does anybody know if there is some documentation / explanation about the Programs of these models? (Not the building instructions, but for the LabView programs, which are quite complex).

THANKS !

They already provide the building instructions for free, so why not the EV3 project files to go with them? Yes, people can develop the robot programs themselves, of course, but not everyone wants to do that. Sometimes, building a robot and downloading an existing program to it is all people want to do.

Hi Laurens,

I have a question for you and i hope to get a reply from you soon. I have been assigned to build a robot using EV3 Kit 31313, and i am supposed to make a robot which uses IR sensor without IR beacon and it is capable of detecting obstacles using that IR sensor.

I would really appreciate if you would please help me with the design such that the robot is able to move forward or backward and also it is able to move its IR sensor sideways.

Thank You.

Hi

Thanks so much for sharing all the valuable content.

My daughter and I have the Home set, bought all the elements to bridge the gap between that on the Core Education set , and now have the education expansion set. She loves EV3. We are struggling to find the project code to go with all the extra robots we cannot build, e.g Elephant or Puppy. Does anyone know how we can get these? We are learning to program ourselves bit by bit, however these may be rather beyond our current level and great to see how that are crafted.

Thanks

I have taken over a school robotics program and have one computer with the education software installed. However, I can not find the programs for the projects above. I am working with our IT department to re-install the software if possible, but are the programs themselves downloadable somewhere if you have your software key?

The Mindstorms education software is now free of charge. You can login with your Lego ID and download it on the Lego education website.

This includes all building instructions and programs for both sets 45544 and 45560.

Hey Layrens

I was wondering if you could help me with the coding for the Robot Arm H25 as we school team and I have created the robot but there are so many types of coding and most of them donk work where the others just stop mid way through. Please, can you help us with this as we are trying to beat another team in the school!

Thank you for the information! I have 2 students that created the robotic arm using the program from the software and neither is working. I have looked at them both and they appear to be built correctly. When they execute the program the display does not show the question mark prompt after it initializes. I was wondering if you had any suggestions as to what a solution might be?
