In this tutorial I will work with you in a step by step process explaining through visuals and written instructions on how to create an Obstacle Avoiding Robot Car. This is a simple start up project with the arduino microcontroller and the arduino motor shield.

Bill of materials:
Arduino motor shield
Custom built/bought (ebay) car with motors on each wheel
bread board
ping sensor (ultrasonic distance sensor)
servo motor


Step 1: Step 1

For the first step I bought a simple 4 motorized car and assembled it.  Before placing the top plastic platform i wired the right hand side motors to a single wire and the same process was done to the left hand side. After connecting the wires, the battery compartments were placed for this example i used a 9V battery to power the arduino and 4 AA batteries to power the motors (however if you want more power input to the motors i suggest adding more AA batteries). Finally the top platform is placed to cover the wiring and batteries.

<p>Awesome project man! please send me the code at aaryagreen@gmail.com</p>

May u please send me the code at jvirgil1106@gmail.com by like today. PPPPPLLLLLEEEEAAAASSSSEEEE
Plz send me the codes
I make this type 4wd robot car.. I have Arduino uno r3 board,Adafruit motor shield,4 Bo motors , 4 wd cheeses,1 servo, 1 Ultrasonic distance sensor,some jumber wires , &amp; 9volt Battery for Arduino &amp; 11.1 Battery motor shield supply.. Now i need the code .. pl send the code sj28550@gmail.com
Mr.Lebrend <br>Great tut. I was wondering if you could email me a copy of the code so I'll have a template to follow
Hey, great instructable! I am working on a similar bit with tracks and was wondering if you would send me the code you used so I have a place to start.
