Let's Make Robots!


Programming a Picaxe in Ubuntu

Well, a small comment in the shoutbox caused several guys to download Ubuntu. Good choice, I like it! Here's a walkthrough to programming a PICAXE in it.


STEP  1) Download the Linux Axepad here- http://www.rev-ed.co.uk/software/linaxepad_100.tar.gz

STEP 2)  Extract the files to a folder on your desktop called "LinAXEPad" or whatever you want to call it.


i am lookin for new and creative robot ideas. I have an arduino mega. what do I do?

Enclosures for random electronics!

Well, most of their cases aren't very big, but they have alot of choices! Waterproof, vented, locking, PCB screw-able, you name it! Also have enclosures for keypads, scanners, touchscreens.. pretty awesome!



video of yellow drum machine 3

ok, i know the competition is over already but 3 hours before the final due hour, my computers power supply went to "sleep"... more of a "BANG......SIZZLE.......SMOKE*......sleep". so i couldnt submit it. however unfortunate that was, i thought it would be a waste of time if i didnt submit it any way, just for the hell of it.

....yes, i did cry.

firstly i would like to apolagise to fritz if this invaded any copyright laws that i was unaware of so please dont sue me.

anyways, this was my video.

Interesting vidoes - OT

The Valkyrie

Hi all!

So the Beast is dead, buried, gone .... I actually intended to keep it as it was but hey I needed the parts :)

The new machine (Valkyrie) is basically completed and since the keyword for this one is ADJUSTABLE I still have to adjust things :D

Will start soon a new robot page for it ... stay tuned.. 

The challenge of building a 1st bot..


I got my arduino mega in the post a few days back and having been playing around lighting up LEDs. Thought id get started with constructing my 1st bot. Hence i rigged up 2 motors, a dual mc33887 motor driver, a 6v supply and the mega board. Uploaded a sample code to see if it would turn the motors. Voila!! Nothing happens. Nothing whirring, no sound, no ecstasy. No nothing. 

Its quite obvious that my bot wont perform with stationary wheels.

Still trying to find a solution. Images of connection, mc33887 truth table and sample code below.

Zodiac display done.

Edit: Added some more photos to the bottom. Those were taken with the curtains shut. Also took a short video.

Finally completed the zodiac display. Aside from the sickly colour of the top and 1 of the red LEDs stopped working after I glued it all together, I`m pretty happy with the way it turned out.

srf05 measurements to lcd readout - code snippets?

Hello, here I am again, asking for some help. I am currently using fritsl's srf05 code:


Ping Flatlined, little to no input...

my ping has little to no response. when i debug, it always says 0 or 1. it used to say 1500 or more sometimes. could it be a connection error or a problem with the sensor? i cant afford a replacement sensor, so if it is the problem, please tips on how to fix it...? please help

Code Below

programming language BASIC 2.5

The Ping is pin 15

pix coming around noon


Results of the Mr Basic competition


What started out as a good idea got complicated. Sounds like any robot-project? Well.. perhaps this is why; the contest works / not works like the robots it's driven by.


DAGU first let me taste & try some of their products. Really good products, and DAGU was (and are) really polite, nice, fast responding, fair.. the kind of people that I'd like to support!

Super Star !

Playing around.  Please send links to your friends if you think it is fun!

Sharp sensor with my phidget control

A quick video of me playing around with a sharp sensor mounted on my robot arm.  This video demonstrates the flexability of my custom servo and inverse kinematics control written in C#.  Nothing spectacular.  In fact, it's in poor shape at the moment, but I wanted to post a video becuase it's been a few months since my last robot video.

Zezinho, the poser - interactive installation

This is the final result of the first stage of this project. An installation where zezinho calls for visitors and when a visitor reachs the mixing controllers he waits for new poses.





Love-voting is fashionable as well!

I am very sorry if anyone was hurt by my bad karma!

However, it helped ;)

Weekend is closing in, and we are starting to see who should win this competition.

Needless to say that everyone participating is very cool, and have contributed to the enjoyment of all of us. Seriously. Thanks for the laughs and good times following your work!

And I truly hope that everyone have had fun building, and documenting.. and that the competition and the evil in "only 3 winners" is actually in the background of the whole experience :)

More hate votes, please!

The LMR DAGU Contest is comming to an end. But everybody in here are so fu**ing nice, and that will not do.

Oh, you are so nice, your robot is so cool, I give you 5 stars, and you too, and you too.

Heck, where is the competition in that?

How can we ever find a true winner (3 true winners) when the call is so close?

What to do? Hate! Fight, mean stuff, we need the dark clouds to fill the sky in here. Remember this is about money, kill!!

Automotive uses for arduino

so this is a non-robot kinda deal so i'll blog about it just to let the people that aren't in chat know whats going on. progress on all my bots are slow. got a few projects going on right now including rfid entry in my car. right now its on breadboard im using my dorkboard and the prfid reader. when it senses the correct card it activates one relay to act as the unlock switch and then it will also pop my door. see one fo my other pastimes is car audio and customization.

more pics of my robot

Just a bunch of pics for my project OPUSfront.jpg

Interior, minus the speakjet. You can see my add-on H-bridge, as I burned out the A/B contacts when I was trying my first robot project. You can also see the bottom of my home-made Picaxe board and it's download jack.


Parallax Propeller Expo 2009 - West

On 2009.06.28 I went to the Propeller Expo at the headquarters of Parallax in Rocklin, CA. USA.

Preparing to launch

After reading and learning a lot from all of you, I have decided to write my first post to check all this before I post my first project: Mr Jeep Basic.


I recently opened a thread in the "Electronics" section as Bluetooth dongle comms which generated some good responses.

Then I opened up a robot project which I had to delete ( I'm also one of those people who do things before I have read the rules :>{ ) so this is where it is going to be documented.

I have now installed Eagle, figured out (again) how to connect components together (I was not selecting "Nets").

Starformers (featuring Oddbot, Fristl, and with courtesy of Chris the Carpenter for a really quick appearance)

 Well, this was supposed to be my entry for Oddbot competition, but i realized i stupidly misunderstood the rules... I thought that you could use a cardboard/wooden robot, but when i read the comments, i finally got that you have to use a cardboard robot... I thought the main rule was to make a funny video about robot, even if you don't use a real robot. (yes, sometimes things are a little hard to get when english is not your first language!)

So i guess i'm off competition, but i didn't want to think that i wasted my time so i post it anyway... 'hope you'll enjoy!

Bluetooth Dongle Comms

This is an Open Source, Collaberative project blog.

The aim is to use commonly available Bluetooth USB dongles to enable a PC to control a free roaming robot.

In my case the missing link which I have been trying to get working since about 2001.

The idea is to have an autonomous PC controlling the robot remotely (WITHOUT A CONNECTING WIRE ), so that I can test some rather radical Artificial Intelligence ideas that I have.

Entry For Oddbots Robot Video Competition

Hi all, it's 2:44 am (yawn), and here is my video.


I spent ages trying to work out the music for it only to find out just before uploading it

that Youtube will probably mute it :(


Oh well. if it happens i'll try another service.

anyway do enjoy. 


My First BatchPCB, er batch

So I finally got my first home designed PCBs back from BatchPCB.  As a bonus, I got double the parts I ordered.


My L298 Motor shield:


My Q1114 sensor board (for line following/wheel encoders)  The mounting holes will need some rework.


End of school/ New calculator

Well as of lately i havent been to active on LMR (youll have to excuse the lack of punctuation and poor grammar as ill be writing this in a hurry). I got out of school this monday and i still have 2 remaining finals, which i feel woefully unprepared for, one of them being tomorrow. On top of that i recently ordered some bike parts from england which put quite a hole in my wallet thanks to the exchange rate. But, as of today i own my first graphing calculator which cost me $150 or two weeks of work.

Edge lit zodiac display.

The school I work for runs extra Summer School classes over the summer break here in Japan and all the teachers are given some certain amount of freedom in how they teach the curriculum. Everyone is encouraged to make displays, signs, games etc. Basically let your inner child out and make some cool stuff :)

Part of what I have to teach is the western zodiac. The section in the kids textbook was really lame and everyone knows LEDs make things 100x better so this is what I have come up with... the LED-edge-lit-zodiac-star-sign-display!!

Heres the basic plan:

Another great idea that I didn't have

The Arduino Experimentation Kit (from oomlout) is a pretty damn slick thing. Usually I'm one of the shit talkers about Oomlout's stuff (they think a lot of their laser cut plastic). This thing isn't quite as pricey as I'd expect from them though. At 80 USD it _might_ actually be worth buying the kit instead of ordering parts from different places (and then paying multiple shipping charges).
