Let's Make Robots!

My first robot, A 4 legged walker, Still a long way to go :D

Hello and greetings from Norway.

Since the winter is creeping upon this very cold land that I live in, and the sun is hiding just about all the day, its time to start some indoor project.

I have always been fascinated by DIY robots and have had many "Brilliant" (horrible stupid) ideas for designing and building them.

But finally i have started a robot project for real. wohoo!

 

Just some random thoughts

It's 5am and I'm still working on a project, not a robot or even bot related project *sigh*.  We all do what we have to do in order to clothe, feed and shelter ourselves and those we love if we they live with us.  This got me thinking of my bot Leo, and a few objectives I have for him such a new body for himas being able to 'feed' himself, and making a bot 'home' for him.

Question: Arduino vs. Illuminato?

Has anyone had any experience with the Illuminato: Genesis board? I want one, but I need it to be 100% arduino compatible (save for the bling() function). You know, me being new to this stuff and all and the slight chance I may need to copy and paste a little. ;)

 

Anyways, anyone?

Is this cool or what?

Just had to share it :)

Robot Stupidities From Internet - Part II

The previous page begins to be long to load so i'm starting a new one!

my new project

my new project is a bot that helps around the house.i want to make one for my mom i want to have a charging station that it atonomusly charges it self.im probly going to have it eather vacume or sweep with a swiffer pad.im going to use adrino and about 6 servos.for a charging station im going to have a botton on the bak of the bot that triggers a relay so it dose not fry components.

the shell of the bot is eather going to be a plastic case or a form of paper machea. strenthened with chicken wire or fabric so the user could paint it

Phidgets! Summer is over!

Wow, I must be the slowest robot builder in the world lol.  I've been playing with this idea for a couple of years now lol. Winter is my phidget time! Here is a video of the software I am creating to work with a SES and Lynx6 arm using phidgets.  The video shows how i've created the same movement delay for my full robot arm that I have for each individual servo using inverse kinematics.

Hoping to come up with something reasonable to control this arm over the web on my webpage.  Probably an overly complicated internet dog feeder or something using distance and touch sensors.

Realising a Dream

I just ordered all the parts for my very first robot.  I don't remember the last time I have been so excited.  Ever since I was a kid I've always dreamed about building and owning a robot but I never thought it would be something that I would be able to do.  I believed that it was just a dream and my life was shaped accordingly.  That is until I discovered instructables.com  about a year or two ago and saw that other people like me where building robots on their own.  You don't have to work for Honda or go to MIT to build a robot!  I have done a lot of research over the last year and a

Artificial Intelligence Idea

Okay, so I was bored in math class. I came up with this idea for AI. What if you had 2 picaxes. One controlling sensors and locomotion, and one that had certain objectives (battery level stays above critical, don't let your gyro tilt too far, etc) for basic survival implanted in its code. Now what if, as the robot zooms around the yard, it flips. The gyro objective has been violated. the robot rights itself, and the second, objective picaxe starts comprising a new code to burn into the first one. It does so, and then the robot is off again, with a new code.

The journey of the "Three Axis Low-g Digital Output Accelerometer"

Finally!!

Today FedEx came to knock to my door...And here it is! My three axis accellerometer!

Indeed, I forgot that I asked it as a sample a few months ago. It has made a looooong journey to come to me (from YUEN LONG, to be exact):

So this is package that i received:

Zen Master

I'm building a robot with many different voltages here.

I have managed to avoid voltage regulation by cheating, I run the motors that are rated for 4.5 volts at 6 volts from a RC NiCd battery, and I use an RC Electronic Speed Controller that can give 5 volts to the RC receiver, the wireless camera and the Picaxe. I feared that this might be a problem and turned to the all knowing LMR forums for help. And help I got...

Fritsl answered:

My very first attempt at robotics

Its my version of the "start here" robot.

Its a Picaxe 28x1 Microcontroler driven 2 wheel robot that is guided by infra red sensors.

So far I have a box of wrong parts. An Assempled Picaxe 28x1 using a single 330 ohm resistor instead of the yellow chip.

The wheels were made by myself and mounted on a Tamiya Four speed double gearbox assembly.

All My photos can be seen on my website www.izars.com/robo

I will be using a GP2D12 ir sensor which is not recomended.

TSA Robot

Hey guys, well I saw that Fritsl was getting on me for having this project in the robot parts but since its still an idea he got pissed so I crawled over to blogging!

Ok, so the workers on the project are Jonny, Colton, and Me.  We are entering this robot into a school competition and the objective is 1) Build a robot that can complete the course.  The course is drive up a ramp, grab a 1 pound trophy and drive down the other side.


Shopping List:

Homemade wheel encoder

Basically I just printed out one of these (laser printer recommended):

encoder_40_s.gif

...And attached it to a wheel (double sided tape recommended).

Then I hooked up one of these (a 2$ IR sensor: QRB1134):

...And attached it to the motor pointing towards the wheel.

SSS - Servo Suspension System

This is my first experiment with the MakerBot. I am totally thrilled with this machine!!!

SSS (servo suspension system) is designed to support standard servo motors and act as a basic suspension. It is still a work in progress and has not been tested yet.

Will update results as soon as possible (still waiting to have my lab back).


I would like to know everyone's opinion on this  :)

Um, this is wicked cool - micro laser scanning quad prop air platform

Just what I need for around the house.

XMOS - Tutorials

My XMOS entry was to create tutorials that not only taught how to use the XMOS but also lead up to explaining complicated robotic principles as well as good coding standards. So far I have been trying to figure out what to make a tutorial about. Below is my list which I will add or subtract from depending on the XK1's capabilities and the complexity of the tutorial.

Found the correct motors for Leo

Well found the correct motors for Leo, less than a $10 fix, actually $7.16 before S&H. Polulu.com wants another $10.95 for S&H.  I don't mind paying for S&H but would rather wait till I ordered more than the S&H is going to be.  I might get a few extra motors to put on the swap board and see what I can get for them.  $20 for 4 motors, or $30 for 15 motors, you do the math and see what you come up with.

Arc Point Art

Well, I had some fun in the attachment. I would take a sheet of flexible circut stuff, and charge my 24Joule Capacitor bank. i would then short out the points between the plate and the wire, vaporizing the copper at the point, creating a black spot. In the attachment, I spelled KL!, mostly because I diddnt have that much to mess with :)

 I was thinking of doing LMR next :)

Jinnarin's First Robot

Hi everyone. After weeks and weeks of tracking down parts and waiting for them to arrive I have finally started construction on my first robot today, i'm so excited! I am following Fritsl's tutorial "How to make your first robot". I would like to thank Fritsl for inspiring me to make a robot!! This is something I have wanted to do for a long time but never knew how.

 Now on to the pics!! (sorry for the low quality pics, I am hoping to get a new camera next week.)

Environment mapping

I'm currently working on an application for mapping the environment with a range sensor. Right now it's only a sharp sensor (GP2D12) mounted on a servo that is turning slowly, while the readings and corresponding servo angles are being sent constantly to my PC via serial. The program then converts the angle and distance to x/y coordinates and draws a map.

My 1st non-breadboard circuit :)

I know..a lot of you good folks could solder before you could walk and probably sleep with a soldering iron under your pillow (hope you remember to turn it off :), so here is this guy in his 30s bragging about his first circuit. Pathetic.

However soldering is a major challenge to me and actually the main reason I didn't get started with robotics years ago. It's just not easy for my unsteady hands. So I'm very happy to declare that I just finished my 1st working non-breadboard circuit. It's a motor+servo shield for my Arduino.

Robotic Self Healing Chair

that‘s an awesome self healing robot , i have found that video while i was searching on the web , watch that !!!!!

Funny video

By no means robot related, and I will not try to draw any paralels :)

It is about time! (SpeakJet visited)

Hey, I can hear it now! You've been here for HOW LONG and you haven't POSTED A BLOG????

Hey, I'm I just not a very "daily blog" kind of person. It takes me FOREVER just to design and build something. Course then it is often "over-engineered" - so of course it takes me a long time, and I just don't take the time to blog. :-(

Anyway, the time has come that I at least try a little bit to break this bad habit...

For awhile, I'll need to catch everyone up with what I've been doing - maybe I can do that over the next few weeks (or months). :-()

Habot v1.1

Function work now, trying to do funny thing.

1. tank can go forward, backward, turn right and left.

2. Detect the object distance

3. stepper motor can turn to absolute angle.

4. detect distance on every angle of stepper motor and find the shortest distance of every angle.

 

 

Nerd

So, I've been to London, UK.

The entire department at work went there for "seminar" which means we did two 30 minutes meetings, And spent the rest of 3 days shopping, sightseeing, going to concerts and other touristing...

Our plane back was delayed and the bunch of us spent the time talking about what we'd done. Some had bought shoes and clothes, one girl had bought jewelery, one had bought records, and so on..

What about yourself? -someone asked me:

Wheels

My wheels arrived. They're too small! *sob*

In the virtual, matrix like world inside my head, 3 inches is alot bigger than in reality..

Here are the motors:

Stepper Motors

And compared to the wheels: (!)

Oops.
