"A ROBOT MAY NOT INJURE A HUMAN BEING OR, THROUGH INACTION,
ALLOW A HUMAN BEING TO COME TO HARM"

First Law - Isaac Asimov

When I started to work on this first prototype I knew absolutely nothing about this field, except for some basic skills of electronics and programming.
I was driven by a strong curiosity and I wanted to get closer to the world of robotics. Someone had mentioned this revolutionary platform called Arduino and I was interested in understanding the capabilities. So I rolled up my sleeves and I tried to build a simple prototype capable of interacting with the environment.

The main goals were to cover the perimeter of an area, identify obstacles and react according to the ambient light.

This is the structure
NINO Alpha Structure
and this is the result
NINO_1

 

 

 

 

 

 

 

 

This video shows how this machine works.
Please forgive me for the bad quality (video and presentation too), unfortunately the audio is in Italian and I'm working to complete it with English subtitles.
Thank you!


In the video I'm using a simple program on PC to control NINO but that specific one was full of bugs, you can download the working version (as VisualBasic project) in NINO Beta Download Section.


Components list:

  • Arduino UNO
  • Motor Shield
  • Xbee Shield
  • Xbee Module S1 (100mt) x2
  • USB Dongle for Xbee (essential, also to program the modules)
  • DC Motor x2
  • Infrared Proximity Sensor SHARP GP2D120XJ00F
  • White Super Bright LED x?
  • RGB LED
  • Photoresistor
  • 150Ω Resistor x3+? (as many as you need for headlights, depends on how many LEDs you want to use)
  • 10KΩ Resistor
  • Jumpers
  • Mini Bread Board
  • Cables
  • Battery


About the battery
depends by your components, how much current drain your DC Motors, LEDs and so on. So you have to know that ideal supply for Arduino UNO/Mega is around 7.5Volts. The best thing to do is to choose a battery pack with this voltage (Ni-Mh, Li-Po) and the correct mA/h (based on your current draining) but x4/x6 standard AA battery could also be fine.

Regarding the frame you can choose/built the one you prefer, or take a look at this .pdf document where I collected the main components used for NINO.
