This instructable will describe how to create an updated LEGO CAMLU (Computer Activated Motorized LEGO Unit).

My students and I built literally hundreds of radical variations of the LEGO DACTA 1038 robot. The original plans date back to 1985, and I have not constructed the model for years- certainly not since the tsunami of new LEGO components.

I attended BrickCON 2010 in Seattle, and observed the robotics competition. Most of the robots with modern LEGO servos and components did not move much faster than the original LEGO 4.5v robots of the late 1980s. It occurred to me there is no updated version of the CAMLU, using any of the succeeding motor systems. I thought it would be fun to resurrect and update the original CAMLU. It would be fun to enter it into a competition with a Mindstorms bot. 

This particular CAMLU uses the LEGO Technic 9v motor. I have constructed variations using the 9v mini-motor and the Power Motor systms.

Note: The CAD images were generated in LDraw/MLCAD . The avi file was captured from LDView . The nice rendered images were created with L3PAO, LDView and POV-RAY.  Additional editing performed in GIMP.

Step 1: Gather Your Parts

You will need to gather your parts. These components are available from BrickLink (www.bricklink.com - my preference), and often come up at Craig's List or ebay. I haunt yard sales! Elements can always be purchased from LEGO or one of their retailers.There are a variety of robot controllers on the market (The PCS Brain is available on the web).

simpel construktie goet gedaan
Not so. This is an original model that I rendered using fan created software. (All software was cited at the beginning of the instructable). I designed, constructed, and rendered the model. It is a compliment that you think it is of the same quality as LEGO. Thanks. -r
i think this one didn't make it in because it looks like you just scanned the instructions from a lego set and you are supposed to actually build it.
nice job ftking _83702
it is made of drawing haa!
it is a robot
why are you not use a knex?
it is made of lego !!
hey what is camlu 2010?
I have a question... Where does the 'M' in CAMLU come from? Your description of the acronym only provides for 'CALU'...
Doesn't the 'M' just stand for <b>Mighty</b>? :-D
Already fixed. First thing I saw right after I hit &quot;publish&quot;.*sigh* Thanks! -r
Awesome Insructable; clear, nicely written, and we just don't have enough great Lego stuff around here! <br><br>I think your decision to go with rendered drawings rather than photos was a good one -- it is extremely clear what is going on at each step, without the vagaries of background and lighting to confuse the reader.<br><br>One minor comment -- you could make all of the URLs in your introduction active hyperlinks. Just highlight them (or highlight an actual word you want to be a hyperlink), click on the &quot;world in chains&quot; icon in the editor, and paste the URL in the the little text box in the popup).
Thank you for your kind words. <br><br>Re: The URLS. Done. Thanks. -r
