Introduction: Oblobots!

Hello! I am Sara from Makespace Madrid and I am going to present you Oblobots, a project developed by Jorge Medal and me

Oblobots! is an educational do it yourself parametric platform that help parents and teachers introduce children to simple electrical circuits.  It consists on a kit of a 20 cm customizable robot assembled from printed parts. The main part of the robot is the body where children will placed a 4.5V or 9V battery that will be able conect  leds, small motors and speakers with hand made conductive plasticine.

To celebrate Jameco Build Night during August 2013, we used the assorted led components to run another iteration of this workshop at Makespace Madrid. It was a really crowded and successful night and we'd like to thank Jameco and the Instructables team for their support.

Let's see what we need to make these Oblobot: 
* 3D printed parts of the robot.
*Conductive plastecine
1 cup Water
1 1/2 cups Flour
(A gluten free version of this dough can be made by replacing the flour with gluten-free flour.) 
1/4 cup Salt
3 Tbsp. Cream of Tartar /or/ 9Tbsp. of Lemon Juice 
1 Tbsp. Vegetable Oil
1 Food Coloring 


* 4.5V battery.
* 2 mini servo motors.
* some leds for the eyes of the robot. 
Other:

* 1 speaker
* Mini Jack

Step 1: Download the Design for Your 3D Printer.

Choose from all the designs from Oblomobka  available here: http://www.thingiverse.com/thing:24908. Download it and print it. 
To start making some circuits with the conductive plasticine, the most important part of the robot is the body. The LEDs, mini servo motors and others are powered by coin cell 4.5V batteries that fit in the torso.

Step 2: Making Conductive Dough I

Inspired on this tutorial from SSThomas.edu  we decided to explore a new way of making the conductive dough with a Termomix Machine.

Ingredients: 
1 cup Water
1 1/2 cups Flour
(A gluten free version of this dough can be made by replacing the flour with gluten-free flour.)
1/4 cup Salt
3 Tbsp. Cream of Tartar /or/ 9Tbsp. of Lemon Juice
1 Tbsp. Vegetable Oil
1 Food Coloring

Step 3: Making Conductive Dough II

Procedure:

1. Mix all ingredients into the Thermomix with a spoon.
2. Set the Thermomix on the ear mode. This mode is for knead dough. 
3. After a while, stop the Thermo and touch the mixture. If it gets stick to your fingers it is necessary to put some more flour. 
4. Once the dough has reached the desired consistency place the ball on a lightly floured surface.

WARNING: The dough will be very hot! Let it cool for a couple minutes before handling.

Note from SSThomas.edu  ***Store in an airtight container or plastic bag. While in the bag, water from the dough will create condensation. This is normal. Just knead the dough after removing it from the bag, and it will be as good as new. If stored properly, the dough should keep for several weeks.

Step 4: Placing Battery, Leds, Mini Servo Motors...

At this step it is necessary to put the 4.5V battery into the body of the robot, and insert the conductive dough to be able to connect some leds for the eyes of the robot.

Other things more complex can also be made:
* 1 speaker
* Mini Jack
* 2 mini servo motors.
