TOTAL NEWBIE to Robots

hyperwave:
Hello guys ,
I recently discovered your website and I really like it as i always wanted to build a robot like everyone here. What i am asking for here guys is some step by step tutorials or guides to build my first robot from scratch. I don't wanna use any kits I wanna build it myself.You might ask me what it has to do and what tasks it should fulfill. Well actually the basics , I t could have a wheel maybe it could talk (but i think this is hard or?)
Are there any PDfs with pictures as to guide me?
thank you for helping me in advance

If you go into the 'Misc' part of the forum, there is a sticky called 'NEWBIES read this first' atb the top.

That is meant to guide you :)

Hope that helped

Admin's upcoming tutorial about the $50 robot would be great to get started. the links to it are on the home page.

I have a fun robot you could try. It is relay simple its only task is to drive forword and then if it encounters an obstacle it backs up and and terns and then continues on its way it is the first robot I built.To start you will need 2 DPDT relays, 2 3904 NPN transistors,2 DC motor around 5 volts,2 LEDs any color your chows,1 2200uF polarized capacitor, 1 6800uF polarized capacitor, 4 AA battery holder and 4 AAs, a push switch,2 22K resistors, 2 470 resistors, a small bread board,22 gage solid hook up wire(for jumpers and connections), some sort of base to mount it all on(such as a Peace of wood or my favorite legos), and weals two big and a small swivel wheel.All this stuff (except for the base and wheels) you can get at www.jameco.com I would recommend building the base firs and then ht circuit, but you can do it eather way.First we will build the base (please repost me on which type of base to go with and then I will instruct one how to make it with lego or wood construction I would recommend lego if you have then). In the mean time here is the circuit diagram. All of the parts are the same as the parts in the parts list.start Assembly by making  jumper of different sizes here is an example. place the parts and test the only function forword and when you push the bumper (the switch in front of the robot) the robot backs up terns and continues forword.

Steve Joblin:
There are three main "diciplines" of robotics:  Electrical Engineering; Mechanical Engineering; Computer Programming Engineering.

For a simple robot, and as a newbie, I would think that the "electrical" and "programming" aspects would be the most challenging, so I would focus on that.

IMHO, Parallax makes the best "starter" kit (the Boebot).  the mechanical assembly is quite simple.  What makes this such a good kit is the tutorial that goes along with it. It will give you a good intro into basic principles of electronics and programming.  I know you said that you don't want a kit, but as a newbie, I can't think of a better product that will get you started!
