The most useless machine ever

This is a "most useless machine" i made. I used a instructable but it was a comment by "compukidmike" that was the schematic i used. 

here is compukidmike's schematic picture thing  http://www.instructables.com/files/deriv/FCQ/XPAC/G43EFYKB/FCQXPACG43EFYKB.SMALL.jpg 

Walter Update

Walter has been stripped down to a bare chassis...

Walter is being painted.

Damn, I'm getting close.

What I want...

I've been thinking, while troubleshooting, a lot about what I would like in a bot. At first I'd  thought about a bipedal bot, but tracks are more stable, easier to work with, require less programming and unless you are using a large base for a bot it won't do stairs.  To be autonomous, to be able to do tasks without human control, such as recharging itself and performing basic tasks.

Propeller Platform Video Howto

I got a new camera for Christmas (Happy New Year!), and I decided to make a 'how to put together a Propeller Platform' video.  Are these types of videos useful?

I don't think a video alone is enough for a howto (the Prop Platform has a written guide, too), but I was thinking there are a few 'advanced' techniques that beginners might benefit from seeing on video.  What do you think?

Motor Controller Board

Well I've almost had 3 weeks offline and got a ton of thinking done.  The physical design is basically the same, going to use a PicAxe 14M to control four DC motors with two L293Ds. The picaxe will be optically isolated from the arduino, so if the motors, an IC or a wire shorts out and decides it doesn't want to go alone that it doesn't have the arduino as an option as a buddy in IC heaven or hell.

Finally back online

I had to put my laptop in the shop because the mousepad was screwy and it wouldn't recognize a regular mouse. It's all good and shiny now though. Back to working on Leo.

A new sexy mobile phone...

Kari and I have been with Verizon for almost 10 years now and during that time, every 2 years, we get a new, free, nifty phone when we re-up our contract. Now, each and every time I am truly amazed how much cooler my new phone is and how much my old one sucked. Once again, this has happened. I just got a new Envy touch and well... MAN! I mean, really --holy crap!

 What you will find below is FROM A FRIGGIN' CELL PHONE!! (It has a macro function!)

Can you believe the quality?!?!

"Moooo" Rare Swiss Cow Project has begun

Following on from the Laser Experiments i have decided to attach it to some kind of walking Robot.

I am now a avid fan of Theo Jansen -  after rik brought him to light in his Blog.

So far i have Prototyped two pairs of "Theo" legs using "MindStorms" as an experimental base.

It worked better than i could have imagined - these legs go like a Cow on its way to the milking parlour.........

Only problem now is what  medium shall i use to make the final version.....

Cheap and small swarmbots

So. I'm finally building swarmbots. My goal is to have bot that is small (should be 25mm x 25mm, will be ~30mmx30mm) and cheap (less than 50$ per one. even when building only one).

 

 

Woohoo, more bot work done

A little more done, well, another phase started anyway, on my XMOS challenge bot(s).

From the bottom up, an ATMega168 @ 8MHz (with lilypad bootloader), a 74LS14 to put the schmitt trigger thingies on the wheel encoders, and a SN754410 H-Bridge to actually run the motors. Top-right is the KA378R05 3A LDO regulator.

Now to see if it actually works.

 

Laser Distancing Probe using WiiMote - Brought to you by Rare Swiss Cow Productions

Following on from a post here "LoMoR Blog"

I have at long last started work on a Laser Distancing Probe using a WiiMote.

Basically i have equiped two Servos with simple Lasers and strapped it to a WiiMote.

I can alter the angle of the two laser beams (they can be fixed at one angle .....but where is the fun in that)

errrr - i also worked out that you actually only need one Laser (but again two is more fun)

C328R camera and Arduino

Well I've decided to replace my 2.4 ghz wireless camera on Ardbot with this guy:

JPEG Color Camera - UART Interface

While it isn't as capable as the video camera I had planned to use, it has the advantage of having a serial interface that can communicate with the Arduino, uses 3.3v, so my hope is to be able to stream the JPEG images via XBEE to my PC.

How to connect SRF05 with a ribbon cable? (I'm not sure either!)

Well, I was browsing like 100s of robots on this website, many of which use the SRF05 (SRF005) and I see that HEAPS ( I did that on purpose) of them use ribbon cables (which are included when you buy this picaxe 28 pin project board. It seems much neater and easier. It would make things easier and save money. Can any1 tell me how to do this?

Coil Gun Rifle

I have been making soem good progress on the Coil Gun Rifle:

Mr. General Robot

Well I'm officially starting work on my Mr. General robot. I just received the kit today when I got home and was thrilled to see all that was inside! Tomorrow I will start all of the soldering and assembly of the kit. I'll be modifying it quite a bit for the Mr. General Challenge. I just wanted to start this blog to record my building process until it's complete.

Things To Do:

Free day...

Hey, so you've all heard of Free day over at SFE right? Doubtless everyone on LMR is participating, but I would just like to point out something. Buy only what you need. Try not to spend all 100 bucks available to you! Save some for others! If we all used 100 bucks, there would only be 1000 slots. If we used less, say 50 bucks, more people could join in! So please, just remember: This is a gift from Sparkfun. Please don't take advantage of it. Thanks!

Wii - Motion Plus (Nintendos Latest Roll-Pitch-Yaw Gyro sensor ) meets the Arduino

Nintendos amazing add-on wins again..........

Thought i would blog this to get the LMR2 "Think Tank" activated,

......... so come on ..... any brilliant ideas what can be done with it ?.

Nintendo in a bid to improve thier Wii gaming unit brought out a small unit that attaches to the bottom of the Wii remote controller (bluetooth)

The Result is a Roll-Pitch-Yaw Gyro sensor (-: at a very competative price :-) which can be Hacked to read the raw gyro information via the i2C bus.

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):
