Marten de Groot posted an update 3 years ago
I’ve updated the info (included a “How To” for my Finger_Starter kit V2:
And here a video without the spring:
Awesome Marten… going to try these servo pulleys with my new inMoov I am currently building… good work man…
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… 🙂
Yep, I am using 180deg MG995 servos so this should work perfectly and increase grip strength as well…
Have you some pictures from your InMoov ?
Always cool to see other InMoovers growing up 🙂
And a MG995 must do the job 😉
Unfortunately I only have a video of the first inMoov I built almost 2 years ago… https://www.youtube.com/watch?v=7YvCuU4EWU8
Hahah, very cool!

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 🙂
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 degrees which was related to the HK15298. That is the reason, the diameter is larger than your pulley which of course reduce the torque strength.
Tomorrow and the next two day’s I have some spare time during the day 🙂
First I need to finish my Wrist update, this will help a lot to run more freely !
Yesterday evening/night I’ve printed the first parts and one needs a small modification to fit better.
When this fits well, I can draw the servo part…
I will do my best, to show a moving hand this week.
(without any burnouts ! 🙂 )
