Thanks dude! These are interesting designs. Thinking of using all these designs to make my own gripper.

Heres my idea. Using part of the gripper design that's like the one in the shop, and the beetle like gripper rgordon posted I made this. Parts sized and everything. Comments? Changes? Also need to figure out what material to use.

Common guys! What do you think?

Aw dude! This is better, way better. Don't worry, I knew my design wasn't that original. Ill play with this idea. Thanks!

Here's my interpretation.

Huh? Huh? Yes I know the gear on one side needs to be offset a little so the teeth link up with the "fingers" straight. This was a quick job. ill do more to it to make it proper in a bit.

Techno pro. I think that looks good.there might be some play in the teeth of the gears. What about a mini servo for each claw. Or "finger". Its just a thought.

@vhs896, That would work but it's just as easy and cheaper do use the geared setup.

@Aameralis Thanks dude! Ill take a look. If you want, you could try do build the whole mechanism that I have shown.
