'''ROBOT VIDEO'''
Here is an offsite link to the video while YouTube is processing the embedded version...
I created this Instructable for the absolute n00by robot wannabe. I have noticed a huge jump in the number of beginners getting into the hobby and the number of "how do I" questions seem to be mounting. Maybe this humble little Instructable will help one or two create their first robot. You will find basic source code at the end of this Instructable.
Don't panic at the number of steps... I broke the robot down into many tiny little steps for ease of following.
This little robot is nothing more than a simple plywood platform that carries a couple of modified model airplane servos as the main drive system, a microcontroller and a IR sensor. I designed in plenty of room to expand and add on. You should be able to build it in about 3 hours if you have the parts on hand.
The microcontroller I chose is the OOPic R. I picked this micro because the dozens of built in objects and sample codes make it easy for the beginner to get up and running quickly. They can be found from any of the major robot parts suppliers for usually less than 60 bucks. Get the starter kit as it has a programming cable and battery clip included.
You can use any microcontroller as long as you can plug a servo directly into it (that shortens the list, lol).
The servos listed are all Hitec HS-311 model airplane servos found at nearly any hobby shop for less than 10 bucks in some cases.
The IR sensor is a Sharp GP2D12 Analog unit available from Digikey (www.digikey.com). Any of the GP2D12XXX analog series will do the job.
The Tailwheel is a simple Dubro .20-.40 model airplane 1" wheel with mount. Pick one up at the hobby shop where you get your servos.
The wood base is a scrap piece of 1/4 inch birch plywood and the servo / sensor mount is a scrap piece of just about anything wooden. I used a piece of fir.
I made the billet aluminum wheels myself but you can use any wheel designed for servo attachment.
The rest of the robot consists of a few screws and some electrical standoffs.
Without the SPECAIL add on at the end it cost me about $95.00 USD. The special step adds about 50 bucks.
Be nice as it is my first Instructable.

You will find it in the pictures and in the assembly instructions. If you need to buy one try this link for the bracket --> http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD850&P=7 and this link for the wheel --> http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXD811&P=M . Both are usually available in any good local hobby store.
Don't forget, you can use any microcontroller that you have to control this robot. Let me know if you need help when it gets to that point.
I always enjoy a new rating... (hint) lol

you say we can use any microcontroller we want? Will your code work with an arduino?
Check this out --> http://oopicraptor.blogspot.com/
These days you can build a functioning USB based Arduino for under $5 (~2.50 if you do without the USB to UART). See http://shrimping.it/blog for more info. If you can do this project then you can probably build the Shrimp too pretty easily.

thanks :)
I like this project and I've been wanting to get in to robotics and Arduino.
its not about the affordability, they wont just ship you some common parts!! :(
And its very hard to find 'em in India! :(
Watch my website for details: http://babblebot.net
so i need the brai to be small. could you like tell me which one to get or how to make it?? THX
What do you want, SIMPLE or CHEAP?
What do you want it to do?
What do you know about robotics?
What do you know about programming?
What is the goals?

I will leave it up to you, the viewer.
Tell me what you want in a Super Simple (CHEAP) Beginners Robot and I will do a brand new 'ible on it.
You have until December 8th, 2010 to either respond to this comment or send me a message on 'ibles... Do your best.
The short answer is that you do not control this ROBOT, you write some very simple oopic basic code and upload to the robot which then runs autonomously.
The stab at the NEW robot culture... NO, it is not a robot if it has a remote control. I am an old fart comparativly and I don't care what the younger robotics crowd believes, nor do I care what the media crams do our throats. A robot is a fully autonomous object that goes about it's business based on its programmed criteria and sensory input.
Good question tmj61 and no, my stab was in no way directed towards you.
Thank you.

___really simple
Really, if you can cut, glue and screw things together you can build it.
If you are looking for cheap then design your own microcontroller based on any small pic or atmel attiny chip. It is easy to do...

I think you meant "Can I use a 360 degree servo to DRIVE the wheels" and the answer is YES.
