Nervo boards for EZ Robot

[Perry S]

Well we are kinda at this point. MRL is an excellent development platform for the Inmoov project as envisioned by Gael. The MRL guys have been great to me and I appreciate all their contributions. They are truly cutting edge for the open source development community.

Having said that, EZR is turning out to be a really easy to use operating system that makes it simple to configure an Inmoov.

Gael, would you consider making an inmoov interface board that works with EZR? I think your project would be enhanced by supporting two great operating systems.I would like to financially support your project as a potential EZR user.

Just a few random thoughts

Hi Perry,

I think it's more up to me :) (If Gaël will agree your suggestion, I will see what I can do)

I haven't yet a EZR set, so it's hard to tell which option there are all possible.

The most easiest way is to design a EZR > ArduinoMega shield.

So if people like to start with a Arduino configuration, they only need this extra adapter to connect the EZR main to a normal Nervo-Board.

A other option (what will cost more time) is to design a complete new EZR-InMoov shield.

Why do you need an Arduino Shield? Just unplug your servos from your Nervo boards and Arduino and plug them into the EZBv4. Done. EZ. All of the capabilities of the EZ Robot platform have been more than described here, it will really bring your InMoov to life.

I was thinking something like still using the ribbon cables. It would really be an EZR shield at that point with greater current carrying capabilities for the servos, and ribbon connectors. I don't trust the tiny EZR plug to carry all my current.

What I did when I switched over to EZ Robot was solder female connectors to my servo signal wires to connect them to the EZB. All of my power wires were already connected thru a bus board so I just left that the way it was. Works great.

@ Perry,

I see you have used the NervoBoards for your InMoov.

There is a option to use these boards with a EZ Robot controller, without a PCB adapter.

With some servo female>female cables, there is a option to connect only the digital connections between the EZ Robot and the NervoBoard. (the ground is normally connected via the main power)

When you disconnect the NeroBoard from your Arduino Mega, at the bottom side you get all male headers, which normally are connected to the Mega pins.

I hope this info helps you, so you can again use the NervoBoards as power/signal distribution :)

BTW:

I've ordered one EZ Robot V4 developer kit (not V4/2 based), I hope to receive this kit this week.

@ Bob,

The NervoBoard is a Arduino Mega/Uno Shield, that's why I was talking about a EZ Robot > Arduino Mega shield "adapter", so there is a option without any cables to connect the EZ Robot to the NervoBoard.

[Bob H]

That's another great thing about the EZB, you don't need any ' sheilds ' unles for some reason you want to go that way. The only hardware on the main body of my InMoov is an EZBv4.

[Perry S]

But you have some sort of power distribution right? Can you post a pic?

[Bob H]

I have the power leads from the servos all going to a + and - bus board. All of the servo signal wires are connected to the EZB. I power everything ( all the servos and the EZB ) with 2 - 6V 12 amh batteries. Once you get your EZB you'll see how easy all this is and all the hardware you can remove from your robot.

Hi Perry (and other NervoBoard users)

Today I received my EZ-Robot developer kit :)

Here I show you a option how to use the NervoBoards with a EZ-Robot hardware:

 

Just connect all digital pins to the NervoBoard with flatband with female<>female headers.

If I only will use the EZ-Robot system for my complete InMoov, I will use one just for all Head functions (including the camera)

One for all Left functions and one for all Right functions.

And maybe in the future, one for all Legs functions.

HEre is te setup I undd up with. I printed up this case for the Nervo. So if you have an existing Arduino setup with the Nervo boards and want to switch to an EZR controller without having to rework all your wiring all it really takes is about $6 worth of jumpers.
