76% of original size (was 666x19) - Click to enlargeHello friends

I start testing accuring for full body character rig but after many tested i have problem to rigging a fingers of the my robot hands
I am very satisfied with the neck rig, as you can see in the pictures the neck and pipes work very well, but not work well with fingers.
Actually, the body of this model is from Adam's model in Unity!  I deleted the previous rig and also vertex group on Blender.
I try my best to place finger rigging dot on the correct place ..  I dont know maybe I place on the wrong place !
Can anyone help me in this matter, thank you in advance.

I would not rely on AccuRig for robotic fingers. 
Those would be fairly easy to weight in Blender. Not even in Weight Paint mode.
Edit Mode would do fine. Since fingers are rigid, just select mesh and add to respective group with weight 1.000.
And also easy to correctly place bones in bones Edit Mode.

Since it already has a rig, you don't need to create a new one. Just use the characterization feature to retarget.

Hi thank you , no I deleted the rig to tested

Hi thank you , I will check them , also Bone edit mode
