Introduction
Time to build: 2 hours URL to more information: http://video.google.com/googleplayer.swf?docI... Cost to build: $85 Actuators / output devices: 2 geared motors CPU: Picaxe Power source: 4 AAbatteries Programming language: Picaxe basic Sensors / input devices: Sharp IR Target environment: indoor This project requires no knowledge of electronics, and it will not get much into that, it will only start you up with a robot really fast. It is based on a system called Picaxe that is really simple yet powerful. If you know that you want to get more into the electronics part of building,spend more time on learning, and use the system called Arduino, you should check out this First robot-project that uses Arduino and a breadboard .

Before you Start
Welcome. before we get started, here are some things you should know: For your own sake, read this before you go any further If you are looking for an even cheaper and faster project, this one might have your interest:http://letsmakerobots.com/node/87 If you have never build a robot before, the video here might inspire to how easy it is to construct, you do not need special materials to build robots: http://letsmakerobots.com/node/35 To inspire to where you can go from here, I have made a part II

OK - Now let´s get started :)

How to start
How to start a cool* robot for approx $85
This is cool* because:
●● ●

● ●

The electronics used are ”real parts” (not little home-made things that wont really work unless you spend hours of tweaking, and not a kit that you just assemble and that´s it). It is EASY to do the basics, you have a robot within one hour! You can evolve from here, even with the same parts (if you can bare to take your robot apart). It is cheap. This is serious, but fun. This isthe coolest Robot-beginners-project in any way, end of story! :)

Items Needed
Links are just where I happened to find the items from a world wide web perspective. You can use any (web) shop you'd like, of course. Please see this page for "where to get Picaxe" Prices are approx. As far as possible, try to get it all from the same shop, and from a shop located in your own country; to get thebest deals and faster deliverance etc.

1x PICAXE-28X1 Starter Pack
The 28 pin project board in this package is like a game of Mario Bros; Fun and full of extras and hidden features, making you want to play over and again. This includes the main brain, the PICAXE-28X1. This is a little expansive, but it is only the first time I recommend you to get this, it includes a lot of nice basic stuff,you get a CD-ROM with lots of manuals, cables, a board, the Microprocessor etc. Actually it is EXTREMELY cheap. Similar packages cost up to 10 times this price! Be sure to get the USB-version, images in the shops may not match, and show a serialcable when you are ordering a USB. When buying the USB-version, it is not necessary to get the USB-cable as an extra item, even though it is also sold...
