Let's Make Robots!

Actual speed of a PICAXE

Does anybody now how many clock cycles it takes for an instruction to be executed by a picaxe? Does it vary depending on the type of instruction?

Robotic Airship, some ideas :)

So i was looking at some flying robot designs, just out of curiosity. I ruled out helicopters and planes: they require too much precision in crafting and are too complex.. But alternatively an airship could probably be built :)

I've read on wikipedia that a square meter of helium can lift about 1 kg. A square meter means a big balloon, but a Kg is plenty of weight for electonics!

If you use light components, you can probably stay under 0,5 Kg or even less.

Picaxe too slow, how to speed up?

Hello guys. I am working on my laser tag project using a picaxe (btw if anyone's interested tell me :=) )

LMR Global Project - Idea Phase

This thread will allow the build team of Jklug80, rik, Calculon320, slick, Edgee, CaptainTune and robologist to start working on the project and figure out what it is, what it will do and how to build it.

Currently the goal is to decide what the project is (what jklug80 proposed or something else), then we need a name for the robot, then we need a name for the group of 7 who are working on the project. We need a list of desired features, a list of REQUIRED features, and who will do what. LETS GET STARTED!

My whole holonomic future is in your hands.

I want to build an autonomous holonomic robot using omniwheels.  Please advise me from both a programming and from a structural point of view.  Is it better to use three wheels in an equilateral triangle configuration, or four wheels in a square layout?  And why do you think so?  Thank you.

What wrong with my code???

#include <Servo.h>

Servo myservoL;
Servo myservoR;
int myservo = 2;
int myAngle;
int pulseWidth;

void setup()
  pinMode(myservo, OUTPUT);

void servoPulse(int myservo, int myAngle)
  pulseWidth = (myAngle *10) + 600;
  digitalWrite(myservo, HIGH);
  digitalWrite(myservo, LOW);


looks like an interesting new Arduino robot platform. A real 4 wheel-drived robot with Atmega168 processor, Zigbee interface, quadrature encoder wheel encoders.

Sorry, embedding Video from Flickr doesn't seems to work, so here are the links:

Transmiting Video/ serial data

Well after seeing Jim lovells updated bot i've decided i want my next project to go towards that direction. Sorry i still dont know how to link the post right but its here, http://letsmakerobots.com/node/6820. And starting either next year or in a few weeks ill be be the president and founder of our schools new robotics club : ), i think for the first meeting i would want to show a bot that would demonstrate a wide range of tech.
