Help with school exhibit robot.

[robotspodcast]

So I'm part of the research committee of our exhibit.

It is a remote controlled aviation robot that resembles a human and tall as a human boy.

We're starting from scratch here.

I need some help in researching

It should have operating arms and hands.
It will be lifting aircraft parts (but not heavy parts).

It should have one hand for grabbing and turning clockwise/counter-clockwise.

The other has several tools like screwdrivers, ratchets. etc. (should also be turning the tools clockwise or counter-clockwise).

It is saturday today, and we're submitting the proposal to our school on tuesday.

Can anyone help me on researching about how to build the arms and hands and the materials needed?

Thank you.
