problem

My "Putting on the FEZZ" robot is doing great! I will put some (much better) pics up and maybe a video soon.

My "wander" routines are rapidly improving, which is good.

The problem is I have is to keep my little bot on a "leash"!!!!

It wanders around my room, the shared hall and sometimes enters another residents room!!! The reaction varies from delight to being outraged! (It has been threatened with being smashed more than a few times,)

I don't like IR control, because then the robot seems more like a toy (to me, maybe not to others).

Hi I have problem with reading value from 3 ultrasonic sensor. I use Atmega644P and trig is conected to PD5-PD7, but echo from all sensors conected to PD2. I tried read value and wrote to LCD. When I disconnected all sensors the some values are on LCD, but when I connected all sensors and click to reset the LCD is clear.

I have connected an AXE121 to the 28 pin project boarrd. The light on the AXE 121 work according to the line but in the digital input there is no input shown.Also the program with inputs doesnt work on the bot.What may be the problem?

I've got two sets of phototransistors and infrared emitters put together to make two IR distance sensors. They are both connected in the same way, both powered by my Arduino Uno, both with the same resistor, etc. But when I check the values I'm getting from them, one of them ranges from about 980 - 1010, with the higher value closest to the sensor. The other, however, goes from about 350 - 570, with the higher value the furthest from the sensor.

#include <IRremote.h>

#define m1F 6

#define m1R 7

#define m2F 5

#define m2R 8

long F = 1979994096;

long L = 1979994056;

long R = 1979994048;

long B = 1979994076;

long S = 1979994080;

int RECV_PIN = 4;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()

{

  pinMode(13, OUTPUT);

  pinMode(m1F, OUTPUT);

  pinMode(m1R, OUTPUT);

  pinMode(m2F, OUTPUT);

I just bought an Arduino 2560 Board, I was using it with windows 7 and it was working perfectly.

The problem is that now the Arduino is not detected by any of the operative systems, I am currently testing with Mac Snow Leopard, Linux and windows 7. The reset botton is working, and when I plug it to the computer the Power LED turns on......

Any suggestions on how to fix this? 

THANKS!

Hello

I have this battery:

it has 6V, 1.3Ah... I don't have a charger... on the side says:

cycle use charge 7.25 - 7.45V

Trickle charge: 6.8 - 6.9V

and something about 0.4A

Hello,
I have a QRB 1114 and have done a little experimenting with electrical tape on my wheels.  I "thought" that I had this working before in a different setup, but maybe it was not working "correctly" before.

I'm trying to control two motors  by means of a joystick. This means I've coupled the potentiometers inside the joystick to my Picaxe 28X1 and my Picaxe 28X1 to two MD03 motor controllers. 

While testing I'm using only one potentiometer and one MD03. The problem is that I cannot get the system to work.

The program I'm using right now is:

i2cslave %10110000, i2cfast,i2cbyte

main:

readadc 0,b0

Hello all. I was wondering if anybody could tell me how i could connect to my robot? I have built everything, and downloaded the axepad for the intel based mac as well as the usb driver, when i restarted my computer and went to my network under system preferences, the computer recognized the usb as some sort of modem

it gave me the following configuration options.

Telephone number:

Account number:

Password:

Ok, got to the point where it's time to start coding and I got power to everything that needed it and started installing the drivers needed for the Picaxe programmer cable. Well to no avail. If anybody has an idea a walkthrough it would be appreciated.

i dont know what's wrong with my code!

i made a simple code that should make my robot simply avoid walls, stuff etc.

i placed SC-QR-1 (my robot's name) upside-down and pressed [F5] (the "run" shortcut) and watched him move his cute little robot legs..     WTF?

the new code seemed to work untill the walk part was over and he started to turn..    ..left.        and then again left and again and again..    etc.

he is suposed to keep walking!!!

Is my arduino dead.
i have the Arduino deicimela or whatever.
i have my code and when i verify its say "yep she's good mate, upload er".
but when i go to upload er it sits there for ages the IDE freezes and then to me it says "look here mate lets get something right even though i said its all good, im just not in the mood so im not gonna upload it until you make me feel better". however to anyone else it would look like this:

Binary sketch size: 976 bytes (of a 14336 byte maximum)

okay..         so i just finished my new robot(8 servo quadropod)and started makeing a test program.   when the test program was done i downloaded it to the picaxe and it worked! then i started to try out use the srf05 to see if it was plugged in the right way! so i made another program and tryed it and that worked too!
