-Instructions would be helpful, I had to look at all the motors myself.
-Many of the parts do not line up properly. It still works, but the whole thing could be alot tighter.
-The simulated hydraulics were cool, but kindof unnecessary.

On the up side:

The gripping mechanism was really cool! I'm going to steal the concept for a project.

I agree. Please include the instructions in the description of your scenes or add a box that explains everything in the scene.

It's really nice.

OH sorry about that : to move this hand : press any of the arrows and 1 , 2

By the way you can take the concept and make it better , but try not using scripting thing cause that realy erase the meaning of mechanics .
