Let's Make Robots!

Garage cleaning

Been digging all the stuff out of the garage that got buried after the move for this thing.  My main pic for the robot entry is after I took it all apart and cleaned off all the surface rust from moisture.  I had no idea that area was that wet.  I had the thing surrounded by cardboard boxes, and they all look fine.  Damn humid Ohio.

Spam and spammers

It's been discussed often before and long after this thread dies. Spam. We hate it. Period.

Is there anything else or anything more we can do together to stop it?

All suggestions are welcome. Spam is not. 



This project is based on my picaxe version of the mini ir beacon.

Some ideas to expand on this are:

Addition of phototransistors to sense an ir signal and aim the com portion of the beacon towards the target. This could be effective for transmitting location data or possibly map dataThe beacon could possibly have a link to a base station to report on bots in the vacinity.

Addition of a distance sensor for inital maping of local. This may be ommited as it adds extra detail that may not be useful.


Been gone/ working the entire summer and I finally got around to placing my sparkfun order. Parts for the new bot : )



See you guys around

My first one

Yeah, I'm a LMR member.

I will be posting some of my old work shortly.
And i'm working on a small delta robot right now, as a weekend project.

Hope to get someting online soon.

Cheap & Easy Speech For Robots

I am always on the search for cheap hackable devices for robots. I have found a couple here you can use to add cheap, easy, and unlimited speech to your robot.

Basic progress

Here are a map of parts in the Mr. Basic kit

Mr.Basic manual page 3
So far I've dicharded:
The wheels (13&14)
The bumper (17)
The battery holder (18)
The front axle shift metal fixer (20)

and I've mutilated/hacksawed/drilled:
an Axis joint device (5)
both Front axles(7)
The Chasis (11)
one Decelerated pinion chassis (12)

And I know some of the copper tubes (22&23&24) have a dark future ahead dating my trusted hacksaw.

Today will bring moderate love/hate relationship feelings

As a pseudo appendage to yesterday's rant on swarmobotic's without saying anything that might risk bringing dissapointment to people if this doesn't come full circle or even vaguely to fruition:



Been losing sleep over this little fellow:

Docking Station for IsoBot02

Good evening, LMR! Last month or so I had some time to do little progress on my Docking station for IsoBot02. I have fixed IR beacon inside the base. Picaxe 28x1 makes it continiously emit signals.


And after hours of searching around my house, I found proper housing for IR reciever to be fixed on back of 02. Yes, he will be doing reverse parking :)


Ignorance is bliss

Sometimes I really hate the internet.

I assume anyone who's been around for any period of time has experienced the "Honey, I really think we should sell the car and start taking the subway to work...you know...for the enviorment...by the way, did you see where I put the creditcard?"  or "Do we really need two kids? the big ones already moved out but the lill' one just sits there and screams all day..." thanks to some new funky gadget of massive nerdy blinghood. You know one of those day's you just wished you lived in a cave.

Humm B

I Finaly Started The Humm B.

This is an ongoing project that will change over time

i will post pictures soon (I hope) 

i still need to figure out a good motor reversing circuit that will work with a pic.

I plan to use pics to controle the basic operations and sencors in a sort of nural network. perhaps adding a big brain at some point.

some wimpy code for a 16f84a pic, I just learned how to program these. It is just a bump sensor thing for the moment.:


Printable Arduino manual with ALL commands

Well I now have received my first arduino (duemilanova), having used PICAXEs for a few years,  but have a problem.

I do not have internet at home, where I do the programming, and cannot find a printable version of the arduino language manual (if there is one!).  I download a couple of basic 'beginners' manuals and printed them off, as well as the extended language reference.  My main problem comes in that some of the examples seem to be using commands not in the extended reference. 


Laser Tag and Recoil


It's me and my laser tag project again. This time you'll read about me trying to find a solution to simulate the recoil of real weapons to make laser tag more realistic and cool to play.

First part of the page will be, as usual, the brainstorming part. That means that i really do not know what i'm gonna use for the recoil mecahnism (and if i will be using one, if it gets too complicated or costly i'll just abandon this idea) so i ask you for suggestions.

 What does it have to do to properly simulate recoil?:

Nobody's perfect, least of all me.  Here I intend to record some of my roboting mistakes for my own good.  Perhaps you can learn from my errors, or even contribute your own.

Sensor-Based Human Activity Recognition

I have a very ambitious idea for a robot project. After doing some reseach, I found a word that perfectly defines what I've been trying to describe for a while: Human Behavior Recognition, or more specifically, Sensor-Based Human Activity Recognition (SBHAR, for sake of brevity.)

Steam Punk Robots

I was visiting my sister this past weekend. I showed her son Alec some of the great bots here on LMR. Alec has a couple of interesting model engines, and has been trying to generate electricity with them. His dad actually does this on a bigger scale with diesel engine running biodiesel and a generator.

Anyway, one of Alec's engine models is a Stirling engine. He has this model.

ldr test

I made a simple test project just to see how an ldr works... i used a servo to indicate the light level read from the ldr...

The video is a bit shaky, but i think it is good enough for its purposes :P 

What to do...

17 no-longer-sterile tongue depressors, and five mini servos. This should be fun ;)


Still need help with the video portion of this project

This project exists, and works when tethered.  But thats not fun, need send wireless video to a laptop from a surveillance camera.  Im interested in building it rather than buying, so the more help I can get, the better.  I thank those in advance who've read this and are thninking of making similar, or even more elaborate versions of this project.

Diecimila, Duemilanove the same or not?

I've been confuse with the arduino which I don't even know if they're the same or not. I'm just asking if they're both the same, like they got the program codes, same instruction like the www.letsmakerobots.com/node/2164 . So all I'm asking Is the arduino duemilanove the same thing as arduino diecmila. If it's yes then I'm good to build my robot project.
