Hey Warren welcome!!
Why 6 months? Oh well it must be your schedule plan.

Gael Langevin posted an update 10 years, 2 months ago

I just modified the CableHolderWristV4 to V5.

It is now screwed with the servo instead of being glued to the servo.

Wrist Range
Probing my hand I I have about a 180 degrees range of turning the wrist, InMoov (depending on the used servo) about 110 degrees in my case.
I have read through Anar’s version of a 180 degree wrist but it looks like to be a lot of detail work and probing…
Given the range of my MG966R is about 210 degrees another solution might be to…[Read more]

Gael Langevin replied 10 years, 2 months ago

Yes totally do-able. During my design I tested a winch servo which could rotate at 360 degree. What happens though is, more it rotates and more it pulls on the tendons.
Though I have been recommending 0.8mm braided fish line, you certainly could reduce the holes to let your 0.6mm go through. Also I would like to mention that my first design of the…[Read more]

Nervo Board
Can anybody tell me if I need to purchase a second set of Nervo boards for my second Arduino Mega? do I purchase the same set as for the first mega and adapt? or is there a different set of boards to do the right arm and eventually the legs?

Thanks

Richard

Victor Hugo replied 10 years, 2 months ago

Hi Richard! You have to buy 2 Nervo Boards, one or the right side and one for the left side. You would have free outputs in one of the Nervo Boards (because the InMoov for example only have one head) so you can use them in the future to add new moving parts to the InMoov.
You don’t have to adapt the Nervo Boards, are the same.
Bye!

  Thank you for your reply Victor I have ordered a second set.

Right Hand and Forearm

Hi everyone,
I\’m looking to use the hand in a project of mine but I only have a small budget. Would anyone be able to give me an estimate for how much a complete Right Hand and Forearm would cost to build?

Thanks in advance 😀

Mats Önnerby replied 10 years, 2 months ago

Hi. I’m assuming that you already have a 3D printer. The major cost is the cost of the servos. You need 6 servos. They cost 10-20 EUR each depending on what servo you buy. You also need an Arduino UNO. You can find clones for about 15 EUR. An you also need a roll of ABS or PLA. Normally cost about 30 EUR. Then you need some other parts like…[Read more]

So the white is the elastic cord and it runs all the way to the end of the finger, if I juge the white spot at finger tip.

Hi Marten
I think before changing the pullies we should agree what the mechanical requirements are for the fingers.

- Marten de Groot replied 10 years, 2 months ago
  
  Hi Juerg,
  
  Thanks for your input about this.
  
  The good thing to use a 180 degrees pully, is that there is less change to break any mechanical parts.
  A other good thing is, there is a higher resolution to place/hold the finger at his position.

These (below)are settings I use for to print the fingers, but you might want to go with a 100% infill depending on your material and printer.
Print wriargeV3, wristsmallV3,thumb4 with an infill of 30%, 3 shells, best with no support, no raft.

  Yes, I have followed your recommended settings fully. I’m using a FlashForge Dreamer 3D printer with ABS, and this is the first time I have had a problem. I have now reprinted the fingers with 3 shells instead of 1, and I’m ready to retry the drilling later today.
  I’m impressed with the quality of the InMoov model. When assembling the wrist…[Read more]

    Awesome, nothing better than your own settings!
    0.4mm will do the job, but might carve in the plastic after a lot of usage.
    One of the InMoov hand I made was exposed in Paris Tokyo exhibit for nearly two months working everyday from 10 AM to 12PM, the 0,8mm braided line didn’t carve in the plastic, I was pretty surprised about that.

      Ah yes, I was afraid that carving of the plastic would be a problem. I’ll use my 0.4mm for the simpler finger tester then, just to be able to test something. 🙂
      Quite impressive that the hand could do that much work without breaking. You’re clearly in the industrial quality segment here. 🙂

So here a simple test video from the FingerStarterKit:
(At this moment, I only use the default servo pulley which is included by the servo)

Marten de Groot replied 10 years, 3 months ago

Here the Arduino code, which has a servo slow function included:

#include

Servo myservo; // create servo object to control a servo

int potpin = 0; // analog pin used to connect the potentiometer
int val; // variable to read the value from the analog pin
int Pos;

void setup()
{
myservo.attach(9); // attaches the servo on pin 9…[Read more]

    Hi Marten,
    I always like to see videos, they tell so much more than words!
    That carbon filament is great looking!
    I did make a Arduino script when I was testing the carbone foam sensors on the finger starter. I’m wondering if I still can find it in all my data. It could maybe help you or others, as I recall it was a bit of a different approach.
    - Gael Langevin replied 10 years, 3 months ago
      
      Found the script back in my data base:
      
      #include
      
      const int servoPin = 3;
      const int sensorPin = A0;
      int sensorReading;
      
      int pos = 0; // variable to store the servo position
      
      Servo myservo;
      
      void setup(){
      Serial.begin(57600);
      myservo.write(0); // Open finger.
      pos = 0;
      myservo.attach(servoPin );
      }
      
      void loop(){
      sensorReading =…[Read more]

        Hi Gaël,
        
        Thanks for sharing your code to.
        
        The best way to use this sort sensor, is to include a servo slow (step-based movement) which I have included in my code.
        The code what I’ve shared isn’t the code what we need right now.
        It was just to test the reaction from the sensor as I showed you in Eindhoven.
        
        If we use a step-based movement, the…[Read more]

HI Gael. en premier j’aimerai te feliciter mon ton travail, je trouve le robot fantastique, tant au point de vue d’ingeniosité mais aussi pour l’esthetique. Je m’appelle Didier je vis a Zürich et j’ai commencé le robot il y a environ 2 mois.je fais parti du FabLab de Zürich et l’impression prends du temps car nous devons partager les imp…[Read more]
