Instructions

This model requires no scaling to compensate for shrinkage. At the very least you will only need to lightly sand the joints to get a smooth rotation along the axis. The thumb has been "frozen" in place for now. I'm planning a special re-design of the thumb out in Summer 2012. You can use Loctite blue to prevent screws/hex nuts from falling out by the constant movement. This model uses no metal bearings. The "hook" part is used to tether the fishing line to the tip of the finger. The "ring" is used to ease the model manipulation.

Stats: 32 plastic parts (10 distinct parts, the rest are duplicates). 23 M3x12 screws, 23 M3 hex nuts, 5 strands of fishing line, between 15 to 45 dental rubber bands (I used 3 bands per joint).

Questions? Comments? Kudos? :-)

The google sketchup design file is up!

no way robots! neat

Part I is a pretty tough print - but, fishing line tied around an M3 nut would do the trick nicely.

I agree. I didn't anticipate how much room a knot on fishing line would take up. So, I'll have to design a finger tip end cap to house all that in.

Nice, you've got me thinking about Thing from the Adam's family on this one.

How has the fishing line been working for you? Have you had any problems with slack in the line when you let loose of the controls?

I've been asked to make a cable controlled version of Vogal and ABS filament just seems to have too much stretch in it over 2 or 3 feet to provide a quick response t
o the controls.

The fishing line has been great for my application. The fingers snap back in place as soon as you release a line. You can control the quickness of the snap with the number of rubber bands you attach at the joints. Also, you can adjust which joints fold first in a finger by adding or subtracting rubber bands at particular joints. It's simple but effective.
