AVR C is hard!

Well, last week I got several packages of parts with lots of sets of ten. I got ten 8pin sockets, ten CR2032 batteries and ten battery holders, and most importantly ten attiny85 MCUs. I figure I can use this set of parts for a bunch of small projects, but my first project is to make a tiny bot! I've already got some tiny pager motors, and some ir emitters I can use as light sensors.

Converting a PIC program, to arduino C

Hi, i found this code on the net, but i need it in arduino C, i have no knowledge on it, and no idea where to start translating...

there is also this one, in basicstamp i presume...



This is my second robot! With a better understanding of robot building and navigaton programming i´ve came up with this robot! I think that the great improvement … Read more

Fast robot? (as in fast computing) how ?


So right now im planning for my first robot, I want my robot to be as fast as possible,  but I'm not talking speed wise(atleast not yet), rather 'computing'.

I'm thinking learn assembler ? I've understood its a painfull programming language to learn, but the programms are fast and powerfull. Offcource I could probaly solve my computational problems by just buying a faster ic, but those are difficult to get a holdof and not to mension expensive.

4WD arduino romeo programming (how to do several action in the same time)

Good morning!

i have make a robot with :

-platform arduino

-ROMEO 328mo

-three sensor infrared

-apc 220 wireless

-1 battery nimh 12V for motors

-1 battery nimh 9V for ROMEO

i made a sketch for controled the robot with my keyboard and processing "it is good!!

i made a sketch for have a autonomous robot "it is good!!

I liked the look of this

It's supposed to be a dinosaur robot but some of the movements reminded me of a robot chicken.

Looking for Feedback on PICaxe Platform Module

I've been working a PICaxe platform module.  I did a V1 a few months ago, and recently re-did it.  Here's a prototype of V2;


I've used the same power stage as the Propeller Platform sD - it's 5v @ 1.5A and 3.3v @1.5A with an extremely low dropout of 100mV.  Standard power and programming jack, and it has power indicator lights.

I need to make a few changes, so I thought I'd get additional feedback.

Robotic Ants Farm

Well, Aniss1001 brought up in an other topic the idea of creating a swarm of robots. This reminded me of an idea I had 5 years ago, when I was in the States and building Lego Robots. Funny thing, a quick search on the net at that time revealed several similar projects. Also, my inexperience at that time with non Lego robots didn't let me put it in practice.

So, here's the idea:

Last Update: 13/10/09 XK1 first look pictures.

My XK1 arrived this morning via Japan post. Being so close to Hong Kong I might be the first :P But they were sent out on the 9th so those people waiting on one should go check your post box!

Making of LadyBugBot clone

[See updates and videos on the bottom of this page]

Isotope's LadyBugBot looked like fun to make so I thought to give it a try. Also, this bot would make a great gift to someone having a kitchen renovated and I just happen to know one :-)

2 Wheel Drift

I have a 2 wheeled robot - 2 GM10's with little thin wheels.  I've hooked them up to an arduino with an L293.  I have it going forwards, backwards & turning well enough.  The problem is when going forward, it seems to drift to the right slightly.  Any suggestions as to what the problem might be?  Do I need wider wheels?  A proper castor?  (ATM, the front of the chassis rests on the ground). 

Basically, what I'm asking is, with 2 small motors and thin wheels, can I expect a bot to go in a perfectly straight line?


The Sparkler

Recently a funny robot idea came into my mind - The Sparkler.

What does it do?

The Sparkler is a tank track robot. It drives around and waits till you clap your hands. If you clap your hands, it puts a sparkler out of its container (similar like a quiver for arrows), lights it off, waves during the sparkler burns and throws the spent sparkler then away. Yes, defenitely outdoor enviroment is recommanded. And I rememeber now, Picaxe has the music tone playing option "Happy Birthday". What a birthday surprise!

my very First bot - eYandron1





My very first encounter with electronics - a very simple manually controlled robot. The main brain controlling it is a Attiny2313 + a motor driver board based on TIP122 transistors. At the time when I built this, I had no idea about a chip called L293D!

Color Sensor Algorithm


I know the video quality sucks I just wanted to give a view of  what it is doing. The black tube has the LDR in it to hide stray light. Below is a tabl eof the values I got for Red, Blue and Green when different color soda caps were put in front of the LDR. Now I need to take the raw values and put them into some sort of algorithm that looks at the difference between the values before a cap is put in place and after to determine the cap color.
