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 🙂
I think when I’ve finished the new servo-bed, it will saves even more extra weights.
For a quick test I will print 5 servo-adapters, so the CS238MG will fits directly in the original servo-bed.
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…
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 🙂
My goal is minimum to hold a softball or a bottle of water.
The main problem with to strong servo’s (->15kg), they will damage your fingers mechanical way !
Most people don’t use anything like a force feedback sensor.
Sounds good… looking forward to your results…
