This is why we need a 3 fingered claw. Such an arrangement would allow the claw to close all the way down, grasping objects better. Especially narrow ones. You could still put narrow strips of foam on the fingers for softer contact if desired. Maybe even use those rubber finger tip things over the fingers for more friction to hold the object even better. Perhaps even some combination of the two. I may try cutting down an existing claw to make it 3 fingered and play with that. Or maybe someone could print something up? Nudge, nudge, wink wink. Say n' more, say n' more.

Lol if you draw it maybe I can whip something up.

Hmm. I have some spare claws and a dremel. Need to give this some thought.

I knocked this up this morning... Version... 1 Haven't printed them yet but I will later when I get home to see if they work.... When I have more time I can re-work (tweak) them so that they look and work much better. But for now they should close tighter than the original claw...

goodmorning averybody

i think these claws are way to fragiel.one finger for sure.

Way to jump into action guys!

@thetechguru Yes, that's the way I was thinking of doing it. Got all the Dremel bits and blades I need to try it. The required skills may be lacking however.

@Richard_R Excellent! That's exactly how I thought it could come out modifying an existing claw to make it 3-finger-like. Printing a set would save a lot of work trying to modify an existing claw. Might not work worth a darn after all.

@Nomad I don't think the strength of the plastic will be a factor since the servo is not all that powerful. I doubt it could break the fingers. But, again, who knows. Just have to try it and see. Modifying the existing claws, however, would probably make for a stronger claw since they are molded plastic.

For now though, I think I'll wait and see what Richard comes up with.

I like that 3 fingered design. Gives it a more of a hand look too. For now I have put the foam in my grippers for CY which I did a while back. I'm also still thinking of doing an IR/lever switch setup for a lil more sensitivity when closing on lite objects.

there is no guidens for the one finger go's perfect into the two fingered opening. you have to make the one fingered smaller and round up the edges. 3d printed parts breaks more rapidly cause its not all filled up,some 15 % or even 50% it can also burn up the mini servo if the one finger goes not, straight into the two fingered part.iqbot use this tree figered grippers. they use metal rods and metal spacers to guid the one fingered into the two fingerd.thats why you need to round up the side edges.
