21 Paper Hungry Robot

Cut the paper and put it on the cardboard. These parts are to separate space inside of the robot.

Put the paper on the empty Pringles bin and cut the bin along the line. You have to be careful when you cut the bin. As you can see the picture, you need to put the thumb behind the cutter's direction.

You can make the head part as the same we made the body frame. If you have a proper tool, use it. If you don't have, you can just use stationary like a sharp pencil. The hole is used for link frame.

It is very straight forward. Attach the paper on the Pringles and cut them along the line.

There are 2 holes for links and 2 square holds for the servo motor.

If you buy the servo motor, the horns are enclosed. You need to make it secure them using a hot melt glue,

This is an important link for making the head open at the same time when the hand moves.

Because the Pringles bin is not big enough to have a board such as an Arduino Shield. So, we need to make it as small as possible. So, we need to cut the wire and strip the wires one by one. The white material is "Closed End Cap". Wire to cables one by one.

As we made a sensor part, we need to make the motor cable.

If you don't know how to upload a source code file into your Arduino, follow this picture.

1. Select

   1. Board - "Arduino Nano"

   2. Processor - "ATmega328 (Old version - if yours is Chinese version)

2. Plug a USB cable

   1. Wait a 5 second

   2. open "Device Manager"

   3. Check the com port

3. Check the Com port

4. Click upload button

Put the servo motor and the sensor and secure them using a hot melt glue.

Now, let's assemble everything with the Arduino. The first picture shows how they will be connected.

Because this robot is very small size, mechanical parts such as bearings doesn't need to be used. Just use cable ties. Put the horn on the servo motor and put power into the Arduino using USB cable. Adjust the angle of motor and hand.

In order to make the head move with the hand at the same time, you need to assemble the link both the hand frame and the head frame.

Etc.

Let's attach eyeballs using Blu-tack

Done
