Designing a Human-Powered Claw: Pullys, Levers, and Gears

[hispanic panic]

Ok for this project I'm supposed to build a vehicle that is human powered (the easy part). the hard part is, I have to make a claw that will be able to grab things like erasers, balls, and a bucket with a 2.2 lb weight in it. It will also have to be able to grab a ball from a stool and place it on the ground and visa versa.

Can anyone help me on the design onf the claw? IT has to be made out of pullys levers and gears. Actually just 2 of the 3. Any input would be greatly appreciated

use the idea of scissors where the blade is the claw, we can't design the whole thing fo you now can we.
