ButlerBot

This is my design for my new project: my ButlerBot

It's going to have a table where it can pick things and pour drinks into a cup or something.

I'am stil working on the last details of the design.

More info soon....

Its a sumo bot, line follower, and object avoidance, all in one little package.

Interrupts causing problems

I dislike asking questions - usually it means I didn't RTFM or that my Google skills are sub-par.  Or that I'm missing the obvious.  But here we are.  The following advenure takes place on a Picaxe 28x1 project board (that came with the Solarbotics "Start Here" kit) with a resistor pack replacing the Darlington chip.  The Parallax unit is connected to digital i/o pin 3 (though I see the same behavior on other pins).  Output pin 2 is connected to an LED (but the same behavior holds for pins 4-7 which drive the motor outputs).

Here is some code:

Error-hardware not found?

Hey LMR,

this is probably some silly thing i missed but i kinda need the answer fairly quick so, uuhh...ya

I'm getting close to finishing my start here robot and i need to get the servo to centre position... (I'm using the usb cord and windows vista basic). I downloaded the picaxe programming editor and the drivers for the usb cord and the cord is showing up when i go to options> serial port>com 4. But when i plug in my picaxe 28x1 to the usb and press check firmware this shows up: 

Hardware not found on com 4:

Possible causes:

Picaxe Debug

Hello LMR,

I mean this posts for thos who know something about Picaxe:

I need help! Please someone go over the code and tell what did I do wrong so that when I make pin 4 = 1 nothing happens!

Did I miss anything, did I add something that is wrong?  Don´t worry about the spanish parts they are just labels.

picaxe: hardware not found

I tried to run my first program on the 28 pin Project Board. The program is the same as Quick start in the manual.

When I try to download the program, the programming editor says hardware not found.

And it says 1) hardware not connected (it is O.K.) 2) hardware not powered (I checked the power is more or less 5.2 V) 4) chip needs a reset (which i tried several times).

Now I have no idea what I can do. Could you give me advice?

DIY Picaxe 28x1 USB Headphone Jack Programming Cable?

Hi, I'm somewhat new here.

 

I'm in the process of building my first Picaxe robot based on the 'Start Here' Bot. So far I've recieved  my motors and wheels from Pololu and my Picaxe 28x1 Starter Pack from Sparkfun Electronics. Sparkfun said that a programming cable wouldn't be included, but they charged quite a wad of cash for one, so I bought the kit anyway since I couldn't find it anywhere else relatively cheaply like I could here. The only other one I found cost like $60.00!

 

OK. Fine! You won. Big deal...

All my projects has been mechanical excercises and/or remote controlled thingys.

And after I posted my first biped here I recieved messages like "It needs a micro controller!" For that reason I've refrained from posting any of my other projects...

I even posted a rant on the forum about that robots might be robots even though they dont have brains.

Waiting for contenders...

Help with IR Sensor LED020 (UPDATED)


Attached are photos of my circuit on a breadboard.

 

UPDATE IT WORKS!

I posted a video. Ignore the TV in the background. When the universal remote sends a signal it is decoded by the PICAXE (not done manually I found a setting that the sensor can read and decode itself). A LED flashes to show a signal was read. It then shows the number of the code that was sent in the debug window. In a few days I will delete this post and add a turorial. Then its off to making my robot WOOHOO.

Picaxe 28x1 the full package???

Well I know this had maybe been ask a long time ago so I was wondering where could we get the full package of the picaxe 28x1.  This include the USB cord also.  I remember seeing I think an UK site that comes with it but show sparkfun doesn't.  They actually charge you another $26.  That $64 and not including shipping.  Seem a bit high to me.  Forgot to mention I'm from the U.S.

using single resonator with multiple ic's

hi all,

Does anyone know if it is possible to use 2 or more picaxe chips, linked to only one resonator, so they keep time together. I was thinking somthing along the lines of this:
