Let's Make Robots!

New to robotics and need cheap.

Hello everyone,

I am new to hobby robotics and am wanting some direction on starting out.  I can pick up on this kind of stuff very quickly and I know if I get some basic direction, that I could easily do this hobby and enjoy it greatly.  I have lots of experience with programming in multiple languages like c#, c++, java, visual basic, and programming ideas and concepts.  I have been programming for many many years and its a hobby of mine.  So I know when it comes to programming I will be fine.  I also understand basic electronics and princples of electricty and concepts.  I work in a research and development lab and freqeuntly deal with automation type test setups that pertain to the company and what I do.  I want to start simple and easy at first so I can learn the basics but was hoping to do this the cheap way.  I know I will just have to break down and buy the motor controller and some simple things so I was wondering if anybody could direct me to some websites that supply robotic electronics for a pretty cheap price to get me started.  I do not want a starter kit cause I would have to drop over 100 bucks and I also dont think I need to.  I got lots of old electronics that I could easily use for the frame and struture of the robot so its mostly the gear motors and the motor controller that I need to purchase.  Any help would and direction would be awesome!  Thanks!!

Thx birdman and chuck!!  appreciate the help!

to use servos modified for continuous rotation. You would then only need a microcontroller and a chassis.
Case in point, http://highschoolrobots.com/default.aspx

With the above system as with all others, you would need a programmer. PICAXE chips and arduinos have bootloaders already, so their programming connections are less expensive to start with. PICs like the one suggested on the site above require a full on programmer to start with and then can have a bootloader added to them. PICs are, therefore, less expensive than the other two regular options. Once you get past the purchase of a useful programmer that will cost between $20 and $40 USD.

You could always use the link above as a pattern and then utilize a PICAXE chip or arduino.
