Diorama, Bat in the cave

Picture of Diorama, Bat in the cave
The purpose of this instructable is to outline our development of this bat in the cave as well as provide instructions and tips for future engineers hoping to complete a similar project or use components of our project in theirs. The goal of this project was to create an diarama that could educate people. The main functionality of the bat in the cave is for bat to react to a light source in the cave by stretching the wings and lighting up its eyes. Some goals we had in conjunction to the movement of the bat was to make the cave from paper mache and paint it with some of the decoration for the cave to be looking realistic. This tutorial will start with a little background information, then show the development of the basic pieces, and finish by showing the final product.

Tools Needed: Laser-cutter, scissors, 3d printer, wire cutter/stripper, strong flashlight, superglue, drills.

Materials Needed: Arduino Uno, Arduino Motor Shield, Breadboard, Wire, Tape, LEDs, photocell sensor, DC Hobby motor, plastic for laser cutter, resistors of various resistance, 9V batteries, fishing string,  Gorilla glue, small screws, paper mache, hook screws. sharp wooden sticks, spray painter(green/grey), grey painter, fake green turf, rubber band.

Step 1: Step 1: Making the Cave

Making the cave is an important step in building this project; it determines the size of the entire diorama as well as the bat and other components! Using tin foil and cling-wrap liberally, make a sturdy base over objects in the shape of the inside of the cave to use as a mold. Then use a pre-made paper mache mix or make your own (flour, shredded newspaper, soap, and water will work) and cover the mold in a thick layer of paper mache. Once the outside is generally dry, take the cave off of the mold and pull off the tin foil from the inside of the cave. This will help the inside of the cave to dry. Let the rest of the cave sit until dry; this may take 36 hours.
