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.

Step 2: Step 2

For this second step the Arduino, motor shield and distance sensor are all connected and placed on the top platform. The image below is a top view of the final wiring stage. Make sure to connect the external power and the motor wires to the appropriate slot on the motor shield.

Step 3: Step 3

Add the code supplied and watch the robot avoid obstacles!
Message me for the code through instructables and i will email the file. (I cannot figure out how to add text files or copy paste the code to the instructable)
(If car moves too fast or slow change speed values to adjust with the power supplied to the motor shield)

<p>Hello Mr. Lebrend. Will you please mail me the code to me. Mail Id: tousifiqbal.mig@gmail.com. Also Sir, I dont ve L293 Shield. Though I ve got the IC, I just want to connect it directly. So will you please send me the output pins for motors &amp; servo. Thanks in Advance.</p>
if it's OK. I put a twist with a sainsmart 4wd kit but wired the same way. thanks for the great understandable instructable.
hello! I'm all ready. my you please email me the code to georgewilson718@gmail.com

<p>did he send you the code</p>
<p>this is the only robot i have found that uses the same hardware as mine but you did not post the code....</p><p>could you not have just copied and pasted it to your instructable?</p><p>could you message me thew code if you have it still?</p>
<p>Hi, I also build smart car as your project. I got stuck around code that I do not know where is error.</p><p>Could you send to me your code?</p><p>citytech90@gmail.com</p><p>thanks</p>
