USB power for the most part is limited to 2A under the USB2.0 standard.
The average servo will draw between 2 and 3 Amps each.
You will defiantly need a bigger source of power.
I suggest a 6V power supply.
If your planning on using it to power the whole of the Inmoov robot, then a 50 Amp power supply is recommended.

There are two ways to go.
You can use the older version of Manticore, there are instruction on this site in the Build yours menu for setting it up.
Manticore runs on Java 1.8, so you will need to install that and make sure it’s the version running.
The other option is to use the still in development Nixie version.

There are a number of servos out there, most of which haven’t been tested by builders.
I have found the PDI-6221MG servos 20Kg to be great, but they are a standard size servo, so smaller than the Hitec HS805BB and slightly less torque which is around 23Kg
You can find on Thingiverse adaptors for the standard size servos to fit into the giant size…En afficher davantage

The Nixie Version of MRL is still in development and will from time to time have bugs.

Looks like your making good progress 🙂

In my current build, I started with the head, then the torso so that I had a stand for the head 🙂
Now I’m working on the arms.

It is possible with the neck servo to use the standard size servo using a servo adapter.
You can at least put the torso together then and have the neck working.
The arms are going to need the bigger servos.

In this link to Discord, you will find a number of really useful assembly drawings.

These were created by Shido, admin of that discord channel.
He has also posted them in here, the Google Inmoov forum and on Facebook.
Good bloke to get to know and very helpful.

Don’t forget to have fun while you build 🙂
If you run into issues, then don’t forget to ask the community, A lot of us have already gone through the same build process and can now help others 🙂
There are a lot of strong communities of Inmoov builders, all over the world, starting with this one 🙂

You can down load the most recent version from that link. 🙂

What version of MRL are you using?
I found OpenCV only works on the Raspberry Pi with Nixie versions

The driver comes installed as standard on the Raspbian OS.
Either your OS has been corrupted, in which case you might be better off restoring a backup or making a fresh install.
Or
The USB chip on your Arduino Clone is bad 🙁

So far, no ones to my knowledge has a working set of motorised walking legs attached to their Inmoov robot.

The next 9 pins are also pointing the wrong way, they a spare un-defined pins, mostly connected to the serial pins on the Arduino Mega 2560.

The last 4 pins on the Nervo board are pointing the wrong way.
Those pins are used to connect to an Arduino Nano to run the NeoPixel ring.

I do remember seeing another design of hand created for the Inmoov robot by a builder that allowed side to side motion of some of the fingers.
It was posted on Thingiverse.
It does require more servos 🙂

In the world of robotics, there is no dark side, unless you plan to have your robots destroy other robots ect.
There is only different 🙂

In any case, keep on building and posting your progress 🙂

Starting with MRL_Nixie, the WebKitSpeechRecognition allows for a wake work that can be used to restart the Speech Recognition.
That would be a feature in Inmoov2.
Wake words are not supported in the Manticore version.

All he needs now is the hand to become your right hand bot 🙂

Nice Progress 🙂
I must work on Fred’s arms…..

I like the look of the screen in the chest.
What screen is that, and are the STL files available?
Looks like a very nice and clean build 🙂

Keep in mind, I’ve been playing with this for 6 years now 🙂
Confidence comes with time.

It can seem like it at first, until you get to understand how it works.
Most of MRL is based around services, you can write scripts to start and configure service and then link services together.

One of the programs started by the Inmoov program in MRL is Program AB.
In Inmoov its called i01.chatbot
If you open that tab, you can type you commands in there
It’s like talking to your bot with your fingers 🙂

That Amps rating is the Maximum the Power Supply Unit (PSU) can supply, the voltage is the one that can blow things up.
You want the 6V output, most of the gear used in an Inmoov will tolerate a 6V supply, most don’t like going too low.
If you try and draw more than the PSU’s maximum current, the output voltage will drop, and all the electronics…En afficher davantage

Your welcome. 🙂
Don’t forget to post pics of your robot as you progress 🙂

The major consideration is the ability to handle the tension applied.
When you consider the pulling force required, it is quite understandable.
The diameter is not anywhere near as important.
as ling as you can feed it through a 2mm hole and the line will hold 200lb or 90Kg, then you should be all good.

Those eyes look great.
the rest of the print is good as well, but i love those eyes 🙂

Modding also makes you go further in to the learning of how things work 🙂
Good news is there are a lot of Inmoov builders that bring knowledge to the group so we can all learn.
Most of the printed mods in Fred were created by other talented builders.

Would be nice if they stay worky 🙂

Very cool 🙂

Bedrijfsspanningsbereik (Volt gelijkstroom): 4.8V ~ 6.0V
They are rated at 4.8V ~ 6.0V
There is a chance they will die an early death if you run them above the 6.0V

That looks very nice.
Make want to think about getting a resin printer 🙂
All jokes aside, the fingers would look good with resin as well.

Oh, so thats a mini Inmoov.
So cool when you see it standing next to a full sized Inmoov 🙂

The chest part in the middle looks a bit different.
Do you have a plan for that hole?
Are the STL files available?
I do like the skin tones on the head.

There are 2 or three sizes of servo used in the head depending on the version you are building.
The Official version uses a HS-805BB for the turning left/right as well as a MG996R for the Jaw or equivalent.

I found with mine, there is a setting in the slicer called Horizontal expansion.
Setting this to -0.15 in my case solved all this problem and the calibration parts fit together nicely.
This setting can vary from printer to printer and even between slicers.
The setting of -0.15 works in my Cura slicer, while -0.10 works best in S3D on the same printer.

It works for me,

It does have some iterative features, so you may need to update your PDF viewer.

I’m re-building the upper torso and shoulders.
My old printer was not well calibrated and I had a lot of dimensional inaccuracies.
With my newer printer, it’s now accurate, and since the stand for Fred’s new head is not that good, I’m using the upper torso as a stand 🙂

That was it 🙂
Thanks qwenael 🙂

I can’t attach the track to the ceiling in my home (the wife would kill me 🙂 ) but I did build a frame on casters that can help support the robot when I first start testing. 🙂

There are two options here to solve your problem.

You may need to download the older version of Java and install it.
I know the latest version is version 11 and MRL has problems with that as well.

What version of Java are you running?
In a command or terminal window enter

The manticore release of MRL runs on Java version 1.7.xxx or version 1.8.xxxxx
new versions are know to have issues with MRL

Can I suggest the static legs?
They look good and lets your bot stand on it own two legs:-)

This is looking very good, got a nice shine to it 🙂

Where i plan to motorize the legs, this will not be an easy task.

The temptation to print multiple parts at one on the big bed is great, but a failure in on can result in the failure of all the prints on that bed 🙁

The following quantities are for each leg, so you will need to double them for both legs.

Maybe Gael assumes you will forget to print it again when you print the left shoulder or that you will break one ?

You do need two, one for the shoulder rotator and one for the omo…. forgot the name of it, but it lifts the shoulder up using a piston while the shoulder rotate is done with a worm drive like the bicep rotator
