B2B Lab: NXT & EV3 Working Together - Update...


If you own a Mac and are using LEGO Mindstorms NXT 2.0, you might have noticed that starting with Snow Leopard if you have Adobe Flash Player installed, NXT-G 2.1 software will not load. Now, with all the NXT kits that I have, that caused a bit of a panic. Ok, so you uninstall Flash Player!

I am now using Yosemite on my new main computer and guess what?? Flash Player still prevents Mindstorms NXT 2.1 Education version from loading. Mindstorms NXT 2.0 Home version cannot even be  installed. So, now I have to use NXT-G 2.1 without  Flash Player on my computer or I use my Windows 10 PC (sorry not that crazy about Windows). Looking into the near future of not having a Mac that will run NXT-G is a little scary; particularly with all the Mindstorms NXT controllers I have in excellent working condition that might not be able to be programmed. Plus, LEGO is no longer supporting the NXT, as of 2016. Yes, I can use the NXT motors, touch sensors, ultrasonic and color sensors to some degree with the EV3 kits, but the future looked grim for the NXT Controllers, but wait…

Could it be??? Yes, I found a couple of articles from LEGO(R) ENGINEERING blog site - the NXT Controller CAN BE programmed with EV3 software! Of course, not all the sensors and blocks work with it. The NXT Touch sensor, Ultrasonic sensor, Sound sensor, and Motor can be programmed on the NXT with Ev3 software. Even the RCX motor, Power Function Motors (except the Servo Motor), and RCX/NXT Lamp with a NXT conversion cable can be programmed on the NXT Controller using the Large Motor block and a LOOP block of the EV3 software. 

An of course, the EV3 Medium and EV3 Large motors can be used on the NXT and programmed with EV3 software using the Move Steering block or Move Tank block to operate them simultaneously, or the Move Tank with one motor set to zero or using the Large Motor block to operate one Medium or Large EV3 motor. If you use Parallel Sequencing in the program you can run up to 3 motors simultaneously. 


So, what EV3 programming blocks will work with NXT?


Action Blocks:


 Flow Blocks:

 Sensor Blocks:
 

 Data Blocks:


 Advanced Blocks:

And of course,  MyBlocks  can be made.


Q-Tip: FLL teams, consider the possibilities....

Life with the LEGO Mindstorms NXT kit has been extended...


P.S. If you  have working NXT software, the EV3 Medium Motor and Large Motor can be programmed on the NXT.
