I’ve decided to make new Wrist Gears to, so all the Finger-fishing lines are more in line with the servo’s !
The Wrist servo will placed on the Finger servobed and with a axle it will be connected to the small Gear.
When I’ve printed the Gears, I can start drawing the Servo part…
Later I will share more pictures and if it works, I will share all…En afficher davantage

I wish that works, it’s a great Idea
- Marten de Groot replied il y a 9 ans et 4 mois
  
  Haha, my fingers are crossed 🙂
  
  The Wrist servo is blocking the complete way for all fishing-lines.
  With the servo placed on the servobed, it makes it full open.
  So this saves a lot of friction 🙂
  
  (printer is almost done with the last peace 🙂 )

Hello Marten. I came to that exact same conclusion last night while assembling my tendons. They have been very finicky and I am not confident the spring system will hold up. The wrist rotation really plays with the tensions and geometries. I was thinking of a system where the lines ran through the centerline of the wrist. The servo can be moved…En afficher davantage

  Hello Perry, this is what happen with my new setup.
  The servo is placed on the finger servobed and with a axle connected to the Wrist gears.
  I’ve a test setup ready now, so I will upload a video in a short time !

I like the picture of InMoov in the speed car. So now you have two InMoov build up, that is great work.

  Thank you Gael! It was a great weekend and we enjoy it!
  Now i make a try with my new raspberry and Mrl but i want to find a way to remotely control the raspberry from a android tablet.
  Do you know anything about it?

Awesome Marten… going to try these servo pulleys with my new inMoov I am currently building… good work man…
- Marten de Groot replied il y a 9 ans et 4 mois
  
  Thanks Richard,
  Mechanical way it looks good enough for me.
  These pulley’s will need the full 180 degrees from a servo !
  Make sure your servo’s supporting this 180 degree turn.
  
  My next step is to see, if the smaller servo’s are strong enough for the complete InMoov Hand !
  I hope to find some spare-time tomorrow, during my work… 🙂
  - Richard R replied il y a 9 ans et 4 mois
    
    Yep, I am using 180deg MG995 servos so this should work perfectly and increase grip strength as well…
    - Marten de Groot replied il y a 9 ans et 4 mois
      
      Have you some pictures from your InMoov ?
      Always cool to see other InMoovers growing up 🙂
      
      And a MG995 must do the job 😉

        I’m sure you will like the spring, if you hold or take a glass of wine !
        I think the spring has enough pulling power and is more soft 🙂
Gael Langevin replied il y a 9 ans et 4 mois

Great Marten! I want to see when the pulley is set in the servo bed how the servos are acting. As I said in our email exchange, I have burned so many MG996 and MG995, that I do not trust those servos anymore. I never, yet burned a HK15298.
Initially when I created the pulley and the servo bed it was for to solve a restriction rotation of 90…En afficher davantage

The CS238MG servo’s saving a 161 gram of weight and they are placed more closer to the elbow !
Both are a positive part, to safe a lot of friction to all arm and shoulder servo’s

Gael Langevin replied il y a 9 ans et 4 mois

Great work and very nice adaptation. Which software do you use for to do that?
It doesn’t look like Blender. It’s interesting to know because other builders might be interested to see how you re-worked your parts with only the STL at start.
- Perry replied il y a 9 ans et 4 mois
  
  Hello Gael,
  Working with STL files can be a real hassle as they are among the hardest to modify after the fact. As you can see in the pics below they import with thousands of facets so there are not really planar surfaces to work with.
  I use Solidworks to import your individual stl files. It is important to import as a solid body instead of a…En afficher davantage
Gael Langevin replied il y a 9 ans et 4 mois

Thanks for the explaination Perry.
When exporting from Blender to STL format I use a plugin within Blender to check if parts are clean without inverted facets. This plugin did not exist when I started InMoov project, therefore some of my first parts could not come out clean

One of the reasons I do not create parts with too many round edges,…En afficher davantage

  Hi,
  I’ve just started the project, so sorry if my question has been answered previously.
  
  I though that the upper back was for mounting the tablet. does this mean the the robot can operate without the tablet?
  - Perry replied il y a 9 ans et 4 mois
    
    Hi Kevon. You are correct that the position in the back is for the tablet. Some people use other tables or raspberry PI’s or other controllers to run the bot.

Perry a publié une note il y a 9 ans et 4 mois

Making a back cover to fill up the Lenovo hole since I don’t us a tablet. It follows the lines of Gaels back design and matches the contours.

Here some pictures to show the difference between the servo weights…
The MG996R was my first choice for the InMoov hand.
The CS238MG servo weights including a mounted servo-adapter 30gr. less as the MG996R !
So if I will use these CS238MG servo’s for my InMoov hand, it will saves a 150gr. of weight 🙂

Richard R replied il y a 9 ans et 4 mois

They may save weight but they may not be strong enough for the inMoov hand… The hand is not the same as the finger starter. There is a lot more friction on the push/pull finger mechanisms. The servos need to work much harder than the simple finger kit… However, let us know if they work because less weigh is always welcome…
- Marten de Groot replied il y a 9 ans et 4 mois
  
  Hi Richard,
  I’m almost sure these smaller servo’s are strong enough for the Hand.
  (don’t forget the special pulley which I’m using!)
  The spring which I’m using now, is perfect to start.
  If needed, I can use a stronger spring to get more torque.
  I hope to show the results this weekend 🙂
