This is a great little autonomous robot project using an arduino that can easily be completed in a short amount of time. We used a Modern Device RBBB (Really Bare Bones Board) as the brain of our robot. These RBBB kits are also great if you are new to soldering. Not a lot of parts, but just enough to get get some experience with.
Stepper motors
Stepper motors are available new, from surplus houses, or can be pulled from old electronic equipment such as floppy drives. Jameco has a nice selection, also Ax-Man typically has a variety. Parallax sells a stepper (PN # 27964), a little pricey, but comes with excellent application notes.
Look for "unipolar" or "4-coil" or "4-phase" motor (they all mean the same thing) with 5 or 6 or 8 wires. Avoid "bipolar" motors because they require an entirely different control scheme. However, if you find a good 4-wire bipolar stepper motor from a printer, here is a good reference source: Interfacing a bipolar stepper to the Stamp
Key specs are operating voltage (12V is convenient for robotics projects), and either coil current or coil resistance (given one spec you can get the other from V=IR). Look for motors with a coil current of 250 mA or less (coil resistance of 48 ohms or more for a 12V motor). Higher currents do give higher torque, but will also drain your battery faster. Another key spec is the holding torque which is how much torque the motor can resist when energized.
If you are pulling a motor from an old floppy drive, look for a flat motor with five or six leads.
Bunedoggle - Take it to 11
Here's my robot based on the arduino diecimila. It's built from two servos modified for continuous rotation, one standard servo and a sharp ir range finder. The body of the robot is a rechargable battery from black and decker called "pocket power". The wheels and "caster" are parts from capcella. The whole thing is assembled with hot glue.
basic function
The robot sweeps the ir range finder 130 degrees and records the closest object. Objects closer than 10 inches will cause the robot to take action. If this object is more than 45 degrees to the right or left it makes a small correction away from the object. If the object is within the center 90 degrees, it stops, looks left and right, finds the clearest direction and turns about 90 degrees to that direction.
Arduino powered Braitenberg vehicle
Jonathan asked me, if I would like to do a project with him on Braitenberg vehicles. After some research and reading the first couple of chapters in Vehicles: Experiments in Synthetic Psychology, I was hooked in. Here is the first version of a Braitenberg vehicle, powered with two RC-Servos and an Arduino as its brain.
Best of all, it needs no soldering, drilling or hot glue. And if you’ve played already with Arduinos, there is a good chance, that you have already most of the needed parts at home..
MAKE: Blog: Arduino-controlled two-motor walker
Spotted on the MAKE Flickr pool, this Arduino-controlled two-servo walker, demo'd at the recent Dorkbot Bristol. Looking at the images close up, you can see this is an insta-bot, made with just the two servos, some coat hanger, and zip ties.
Ard-e: The robot with an Arduino as a brain
So with spending around $100 you get a remote control robot with a pan and tilt system that could be used to aim a camera, a hacked airsoft gun ( http://inventgeek.com/Projects/Airsoft_Turret_v2/Overview.aspx ) or you could attach a laser to it because thats what you have lying around. If you wanted to be really cruel you could attach a dvd laser to it and burn whatever you wanted ( http://www.youtube.com/watch?v=CgJ0EpxjZBU )
In addition to making the pan and tilt system that is remote controlled you can also buy about three dollars worth of chips, attach sensors to Ard-e and make him fully autonomous. For around a hundred dollars you can build your own robotics system that has most of the functionality of a roomba or a lego-mindstorms robot: It can sense when it bumps into something be programmed to avoid what it bumps into, it can follow the brightest light, smell pollutants, hear sounds, know precisely how far it has gone, and be controlled by an old recycled remote control. All of this for about half of the price of commercial units.
Making an Arduino based Tin Can Robot or how I learned to love hardware hacking
This blog post will show you how to build an autonomous robot that seeks out light based on a toy with a low power DC motor, an Arduino board, and a host of electronic components. Look at the pictures or go and check out a movie of the end product— the robot on a flashlight "leash." I built it with my 6 and 3 year olds over Thanksgiving weekend in stages, and we had a blast doing it. I'm putting the assembly process down as a blog post to get all of the information in one place for people who might be interested in these types of projects. It is written from the perspective of an electronics noob so hardcore hardware hackers or Arduino experts will be bored.
Guilherme Martins - Project Showroom : Easy Arduino Robot Tutorial - Part I
In this tutorial you will see that you don´t have to be an electronic guru, or a super skilled programmer to make a simple, easy and funny robot.
It won´t have any IR sensor or ultrasonic.
So what will this robot do.. you may ask..
It will be an insane light seeker!!

ArduSoccerBot is a kind of teaching which aims to make a robot soccer (in the style of the RoboCup Junior) using a single USB controller Arduino Diecimila.
ArduSoccerBot no pretende ser un robot de última generación para la prueba de Soccer de la RoboCup Junior, el objetivo es implementar el máximo de funciones posibles con este pequeño controlador. ArduSoccerBot not meant to be a robot-to-order test of the RoboCup Junior Soccer, the goal is to implement the maximum possible roles in this small controller.
El resultado que perseguimos es un proyecto de fácil realización en el que estén integrados aspectos útiles para otros diseños: control de movimiento localización de luz (infrarroja), orientación (brújula electrónica)... The outcome we seek is a project easy to perform and where they are useful for other aspects of integrated design: motion control localization of light (infrared), orientation (electronic compass) ...
Con el fin de conseguir un diseño modular y para hacer más sencillo el desarrollo y la reutilización de este robot y de sus partes, iremos realizando distintas versiones del mismo que añadirán funcionalidades sobre las anteriores. In order to achieve a modular design and make easier the development and reuse of this robot and its parts, we will be doing different versions of the same features that added about the past.
