<![CDATA[Is there an easy way to connect M5Stack or M5Stick-C to old Lego Mindstorms Motors and Sensors (Robotic Invention)]]>I have a bunch of Lego MindStorms collections, more specific, Robotics Inventions. They are old but I love them very much. With the obsolete platform for programming the RCX2, I am thinking about (1) replacing the RCX with an M5Stack module and (2) about possible ways to connect the Lego Motors and Sensors to an M5Stack module. Of course, there two challenges to be done, (1) the hardware interfacing and (2) the software aspect. I think I can/may give up with the Lego Sensors since many cheap and more advanced M5 sensors are now available and can be connected readily to the M5Stack module. So the final challenge is the hardware interface from M5Stack/Stick to a DC (6V) Lego Motor. I do not want to reinvent the wheel; if somebody has already invented or created them please let me know. Other ideas and comments are welcomed.

Of course also with the NXT motors and EV3 motors. I will see that I make a video the days once again where you can see how precisely he drives the set values.
@liemph
I will then connect a NXT motor and run it on different values of the encoder! The GlideWheel PF and RCX motor controller for NXT or EV3 cannot be mounted directly on the old motors, because it is designed for the power motors (on these it is mounted with two pins), but you can mount it somewhere in the system on the shaft of the motor. So you can make an encoder motor out of any Lego motor.

You will need the following cables :

  1. this one from NXT/EV3 to PF Power motor connector

  2. this one from PF Power Motor Connection to the old motors

Ok, this is another interesting way not to throw away old Lego motors. I am challenged to make those connectors. Awesome. Thanks.

@liemph ,

Hello,

As you can see, you can connect all RCX engines and also the power engines to the BaseX and of course the old engines of the NXT as well as the EV3. For the power motors there are also adapters to connect them to the X-Base.
The X-Base can control both the direction of rotation and the speed of the motors.
For sensors you would have to use the M5Stack connectors, which are available!

I hope the test helped you !

Thanks, a very nice video that explains everything I wanted to know. The encoder signal is also used by the Base is impressive. This feedback is important for a serious project.

With this adapter and the adapter from power motors to the old ones you can also make NXT or EV3 motors from the old motors which you can drive exactly on angle ! (http://www.mindsensors.com/ev3-and-nxt/19-glidewheel-pf-and-rcx-motor-controller-for-nxt-or-ev3-)

i Get touch as soon as I have tested it, it will only take a little while until Saturday before I can start !!

@liemph

I had ordered the BaseX on 13 December 2019.
Today finally on 21.01.2020 they arrived at my place.
They are working very well, I will test them during the next days and make a little video!

Greeting Skink

Happy Testing !!!

No need to thank me, of course I will get in touch with you as soon as I have received them !
And tell you what my impression of the X-Base is.

@liemph,

here are some more interesting pages about the RCX.
Maybe very interesting for you if you still have so many RCX parts.

  1. https://www.philohome.com/sdk25/sdk25.htm

  2. http://www.mralligator.com/rcx/

  3. http://lego.brandls.info/legbau.htm#code red

greetings skink

P.S. I'm waiting for two of the X-Base units, they're already on their way to my place

Thank you. For long I have followed the first two links. The third is new to me. Please let me know your impression on the Base X. If I have an NXT Lego then I will certainly by the base.

There I was not fast enough @ajb2k3.

@ liemph,
and here how you finish the cables : http://www.philohome.com/nxtcables/nxtcable.htm
Ready to buy there were also times from the company: https://www.generationrobots.com/de/157-lego-mindstorms

Cause I got a couple more ready to go here. But I'll keep them, of course. Since I also have RTX, NXT and EV3 here without end.

Ok, those URLs are helpful. Thanks.

This is the new NXT module for the M5Stack

It comes With NXT sockets which means you can use these adapters for RIS motors.

With a few components and some soldering, it is possible however with the new module we can now use nxt to RIS adapters that have been available for a while.

Thanks for the response. Could you please elaborate more on the "new module". What is that? I have no Lego NXT with me.
