Here's a stumper!

[DanLevin247]

My first class was recently assigned a very difficult, yet intriguing project, and we're looking for help! Here it goes...

We have roughly 4 days to complete this project...


Each project must be automated, meaning once the process starts there is no human interaction with the device.

We must complete one of the following, and it MUST FIT INTO A SHOEBOX ONCE COMPLETE.

1. An automated device that will place a stamp in the upper right hand corner of an envelope, move the envelope, and repeat the process on a new envelope.

2. An automated device that will peel an apple, and repeat the process on a new apple

3. A device that will fold one piece of paper in thirds, and repeat the process on a second piece of paper.

4. A device that automatically will place, and screw a bottle cap on a pop bottle, and repeat the process on a second bottle.

Here is the materials list:

Cardboard
Paperclips
Rubber Bands
Super Glue
Paper
Velcro
Plexiglas
Plastic
Springs
Wood
Small Hobby Motors
Standard Size Batteries ( not marine or car )
Gears.

Anyone care to but their engineering minds to use?
