Let's Make Robots!

The body of the old power wheelchair coming apart

Got the chair in today taking it all apart to get it down to just the frame. Got to see what needs fixing before the build

Concept of a learning robot based on VSLA

My next robot will be based on a variable structure stochastic learning automaton (VSLA) , which is similar to the approach David L. Heiserman describes in his book How to Build Your Own Self-Programming Robot. As I am using quite a lot of mathematical notations and equations I have attached the first chapter as a pdf for better readability. I'll add more chapters later.

Update 22/09/2012: Chapter 2 attached

Goodwill Goods

So, I went to Goodwill the other day and went straight to the toys sectons.  I found an RC car without the controller for $2.  I bought it, took it home, and ripped its guts out, leaving the motors.  It wasn't until today that I saw fritsl's Toy Challenge.  Four year old challenge accepted :)

Introductions

Greetings all.

I have been looking around LMR for a few weeks and I thought I should introduce myself.  You can call me "Bur7ama" or just "Bur" for short.  The 89 stands for the year I was born...23 years old if you don't feel like doing the math.

My PCB Adventures...

Inspired by Birdmun's adventures in PCB's I decided to try my hand at it. I'm no guru, in fact I'm pretty noobish to this whole thing but I thought I'd share some of the things I've worked out with the help of friendly LMR'ers.

All the equipment I'm using is standard stuff that some folks may already have around:

1. Laser Printer. I had an inkjet which will work using a different method that employs special boards made for UV etching but I             picked up a Brother HL-2240 for $60. It was the cheapest no-frills LP I could find.

Great robot shield ideas gleaned from LMR members

I just felt like commenting on how much I have learned from others on Let's Make Robots. This was recently brought home to me when I decided to build a robot shield for the Hobbybotics Hobbyduino Mini. This is a custom bare-bones Arduino compatible board created by LMR member brooksware2000

LMR's new QR code

 

Hello to all my fellow let’s make roboters here is the new LMR QR code. I made today and it works. I made it with http://quikqr.com/ and http://goqr.me/ .I’d like to make a really cool project with it. All suggestions are welcome and I’m thinking it would be really cool to have a 12x12 at maker fairer if anyone is going. Well hope you all enjoy .P

Robot A.I. idea for non neural network approach.

In this Blog I am simply gethering my thoughs in preperation for a long term project. Hopefully some programming Guru's will post some good ideas. Maybe it will inspire someone else. I am just one nueron in the huge brain of humanity.

Personal History
When I was 12, I taught myself to program in GW basic on an IBM clone that ran at 8MHz with monochrome, text only graphics and a 5¼inch floppy disk drive. At that time I wanted to write an artificial inteligence.

Axe - the sumobot

Hello hello!

As you can guess, I am making a new robot, and it is a small sumo!
Features:
- Picaxe 14M
- 2 modified micro servos
- 1 LDR to see the line of the ring
- Sharp IR sensor
- Bottle cap wheels until I make up a better solution (Yes, lol :D)

And when I will receive parts, or get something done, I am going to update this until it is time to post a robot!
Tomorrow (I think) I'm going to post schematics and maybe printed layout ready to make it pcb!

Someone Knitted me a QR!

Hey! How cool is this! My friend Wendy knitted me this awesome QR code...   And it works!

 

 

Rocket Brand Studios

Curiosity

I'm planning on creating a simple robot like "Gwunderer" By. NilsB I have already created the mechanism. When you go in front of it, the servo goes to 180 (up) and when you move farther than 50cm it goes back to 90 (center). This uses an Arduino. I used an Arduino Mega 1280.

UPDATE (6.9.12):

I uploaded a plan and photo of what it looks like.
It seems as though I cannot find my camera...

BUT here is the plan: 

A Game of Kat and Mouse

Reinstituted

Teense 3.0 soon to become real

Hi

For those who love Teensy.... There is a Teensy 3.0 with ARM processor on its way. It will have 38 pins to use.

Paul stofregen requested Money on Kickstarter and after 1 day has already 4 times the amount he requested.

The wishlist

Just to let you all know.

I made a wishlist of parts on yourduino.
In a couple of weeks, it's my birthday :)
I will use all the money from my birthday to buy things from there. (only electric parts, mechanical parts such as wheels I will find some where else for free :))

I will update this blog when I buyed some things!

 

(excuse me for my bad english, just corrected a few terible mistakes :p)

ALF Donation for LMR4

Ok, I will make it short.

As a result of the Campus Party 2012 in Berlin I just donated 66UD$ for the development of LMR4.

Why and how?

RoomBot

Hi all!

 

I'm totally new at this, but I want to learn it!
I have an idea for a RoomBot.
It will be a bot that checks the room for it conditions. (Temperature, co2,...)

More concrete:

Pulse oximeter - Update 02/09/12

I am currently in the engineering phase to build a pulse oximeter. I mainly make use of the following references:

Thanks for a fantastic time at the Campus Party Berlin 2012

Thanks for a fantastic time. You are all very giving and really, really cool persons. And very talented.

You know who you are.

Everyone else; Since Campus Party is a returning, and starting to be global -event - why don't we use it as our way to meet IRL?

Hope to see you next time, next place :)
