I need some ideas folks...

So here's the deal,

I just ran into this cool old robot thing... Originally from the Nintendo 1.0 it is full of possibilities.

The arms travel up while the claws close, they open as they lower. 

The base has room in it for 4AA's and a small board.

The arms can also swivel 360 degrees while the head stays stationary

Also -The base is the exact right size for standard tracks.

Here is the old board (Already thrown away) and the motor to swivel the arms

Heres the inside of the head it originally had an IR sensor in it behind one of the lens "eyes" --There is plenty of room for another board or what ever. The head also tilts up and down manually.

So here's the question...

What would you build if you had the above plus... (what I have on hand)

An 08m, 14 or 18x board

A bunch of darlingtons and a couple motor drivers

2 IR distance sensors

IR for TX and RX (maybe to talk to another bot?)

Some of those sensors for a line follower bot

A servo or two

Tracks or wheels

What would you build and/or what would it do?
