PunkOTTO+

I was in search for a cool project to do with Arduino Microcontroller and I came across this little robot Otto+ .

Although there is detailed information on how to build one in the above link I found it quite confusing with the variety of the files versions and decided to bring here a clear version that works for me with some modification I made and include:

1. New head to fit better the sound sensor, Ultrasonic sensor, Arduino nano+Shield with holes to Voltage and mini usb
2. New Body with customize space for on/off switch, USB charger,18650 Li-Ion battery and LED matrix

To build PunkOTTO+ you will need the following:

• 1 pcs Arduino nano

• 1 pcs Arduino nano shield

• 1 pcs Led Matrix

• 1 pcs Mini USB charger or this for Micro USB

• 1 pcs Samsung 18650 30Q 3000MaH Li-Ion rechargeable battery

• 1 pcs Set of Jumper wires

• 1 pcs On/off switch

• 1 pcs HC-06 Bluetooth Module

• 1 pcs 20Awg Silicon wire

• 4 pcs MG90 metal servo

• 1 pcs Buzzer

Tools you will need to build PunkOTTO+:

• 3D printer to print your parts, I use:Tevo Tornado

• 3D printer filament, I use ABS from: HATCHBOX

• Highly recommended: Soldering station

• Soldering free hands

• Hot glue gun 150W

• Magnetic screw driver set

Steps to build PunkOTTO+

1. Download 3D files and print them

2. Follow Parts assembling instructions

3. Follow Fritzing wiring scheme from fritzing file or PDF

4. Download Arduino IDE and install it

5. Download OttoDIYAPP_121.zip Extract the zip and install the APK file in your Android phone

6. Upload the Libraries from the zip to Arduino IDE - Don't know how? Follow this

7. Open OttoDIYAPP_121.ino with Arduino IDE search for the line Serial.begin(19200); and change it to the baud rate on your HC-06 Bluetooth module! If you didnt touch it from factory the default is 9600. So change it from 19200 to 9600. It should look now Serial.begin(9600). compile and upload it to your Arduino

8. Now enable your mobile Bluetooth and search for HC-06, pair it!

9. Open the App in your mobile and press "Find Otto+" on the blue bar, search for your HC-06 and connect Enjoy (:

I printed it from ABS. But it'll work with any other material.
