Desktop Robot - TIN CAN

Who doesn't wish to have a mini play buddy, who you get to feed and play with . Now, its possible to have one made of old deodorant cans and few easily obtainable electronic components. You can make this from pretty much a carboard box or puppet mask, I'll leave the rest to you imagination. Except the code, the code is provided below.This is my first intractable, hope you enjoy it!

The preparation video is from The IG account "be_like_bla" where it was first posted. You can share you love and experience with this mini robot to the same.

List of tools :

• Mini Hand-drill
• Grinding attachments
• Hacksaw blade
• Strong Glue
• power-bank(optional)
• 
  

List of materials :

• Old Deodorant Can
• pair of googly eyes (optional)

List of electronic components:

• Arduino UNO
• Arduino UNO Connector
• Ultra-sonic sensor
• Tower pro SG90 micro servo
• Jumper wires

Connections :

Ultrasonic - UNO

GNG - GND

VCC - 5V

TRIG - PIN 7

ECHO - PIN 8

SERVO - UNO

RED(positive) - 3.3V

BROWN(Negative) - GND

ORANGE(SIGNAL) - PIN 9

Make sure to use a properly depressurized deodorant can , denting or rupturing an new or non-empty deodorant can can result in accidents. Use a hacksaw blade or a mini drill to cut it horizontally. Along with it, make a hole for US sensor in front , and a slit to allow the wires to come out from can on lower back.

Draw a bare outline of servo with horn , as per the orientation shown. Use the Hand drill to cut out the pieces. One segment of top piece is bent towards outside and used as a hinge for connecting to servo. the bottom of the servo is attached to a platform in bottom piece , which is created by bending a segment of bottom piece towards inside. Servo is glued , and the horn is attached to the hinge with screws. Be mindful to zero set servo before attaching the horn , its always safe to attach the upper jaw a bit open than completely closed.

Take a flat sheet of paper , fold it a couple of times , make an " L " fold, so that the an edge of paper is at same height as robot mouth , when other end is placed on the table robot is in. More or less looks like something to bite for robot. which has considerable flat surface for Ultra sonic sensor to detect.

Use your imagination , may be a mouth looking carboard, fluffy tongue or teeth, its up to you at this point , I added an umbrella as an Hat , and "Zzz.." Symbol inside mouth.

Check if servo motor with "mouth_sweep.ino "and ultra sonic sensor with "Ultrasonic.ino" , make sure both are functioning well. Connect the USB to Laptop & Arduino , open Arduino IDE and upload the " TIN_CAN_V1 " . Oh yeah! Don't forget to open the Serial monitor!!!
