Let's Make Robots!

Gift for LMR Mr.Basic Buyers

Sounds everybody is waiting for my good news.

 

But firstly I want to s

Qwerk control with Processing 2

Here's some more progress towards a processing-based control panel: got mouselook video feed, and keyboard controlled motors/LEDs/sound effects now! Also, I've upgraded to filming in High Def (that version is here- http://www.youtube.com/watch?v=rMHlcNt5O60&fmt=22)

Mr. Suspense

Just starting a build blog for the Mr. Basic Challenge II.  When I get some more progress I will post pics and make a robot page.

I'm still developing ideas, but I liked Gareth's work on a suspension system for the original Mr. Basic Challenge, so I'm starting with that.  My suspension will use steel cable instead of polymorph for a flexible power transfer system.  Ultimately,I want to try a four wheel independent suspension, but I will start with the front axis being on one suspension platform and the rear on another.

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.)

Vendors I Like

I've noticed a few folks on LMR have mentioned their preferred vendors -- I though I might do the same on my blog.  There are more I'll probably add, but these folks are fresh in my mind. Everyone already knows about SparkFun, Adafruit, Electronics Goldmine, SeeedStudio/NKC Electronics and Gold Phoenix PCB -- this list includes stores I haven't seen mentioned.

Tools & metal for building robots CHEAP!!

If you ever need metal working tools or pieces of aluminum, copper, brass, steel, or stainless, cut-to-size and shipped at reasonable prices, please check out: http://stores.ebay.com/Stoners-Tools-and-Raw-Materials?_rdc=1

He has hundreds of stock sizes and shapes in stock at his on-line store, or he will custom cut pieces to your size for only $.25 / cut. Paul Stoner is a super guy to deal with, easy to communicate with, and gets your parts shipped right out.

Running a MicroController off a SuperCap

Because I keep daydreaming about wiring up my house with dozens of sensors, I was wondering how hard it would be to power a micro controller (say picaxe) off a super capacitor.

A supercap is an electrolytic capacitor with an insanely large capacitance. Mine is half a Farad, 470000 uF. But is rated for only 5.5 V. That's the deal with these caps. Higher capacity at the expense of the maximum voltage they can endure. Or simply at an expense. This one costs about $4 at DigiKey.

Weather station project, Radio silence!

Here's a quick project update: I've been busy with studies, work and other stupid things and I haven't had much time to spend with really important stuff - my weather station project. Now that I finally got more time and spent couple of nights building I got radio silence! Oh ****!

Bob Lifts Bear - The Sequel

Especially for Gareth, who requested a sequel. It's all a bit silly, really, but fun making it. My Robonova has a new head, which I've managed to squeeze a servo, led board, and camera into. The camera isn't very good quality, but is an introduction for me in Object Recognition software. Also included is a simple bot using a Picaxe with 3 servos, 2 for driving and one for "Ted". It has all been done using simple delays and timing in both Robonova and "Ted's Truck". The "gun" is a modified ball point pen and party popper. The "bullet" is filed down plastic.

SI1120 Sensor

This is a new sensor I'm testing out.  Hopefully will be ready to go into the new sumo soon.

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

Megan40 - UltraViolet Detectors ( IR is going out of fashion )

This is my latest FireFly codename Megan40 ...... because she sports 40MΩ feedback resistors

If you need detectors that are not affected by ambient light then i highly recommend using UltraViolet LEDs as detectors.

The detect circuitry is finished - next part is to shoehorn the picaxe 08 onto the back to control servo and UV glowtube.

Getting angry about the availability of electronic components in Europe?

Hi there,

it has been a while and I am still working on the stereoscopic vision issue for my small robot. Meanwhile I learnt, that the Parallax Propeller chip is by far to slow to handle and stream-edit an BT.656 conforming digital video stream, at least for what I have in mind. Therefore I am now working on a hardware-based video filter made of discrete components - a poor man's FPGA, so to say.

Robot Betty9 is ALIVE

My robot betty9 is really cool. I built her over several years. She sings at the Riverside Robot Expo.Robot Betty9 - humanoid

Happy St. Andrew's Day

I'm not what you'd call "religiously observant" but there aren't many holidays that apply specifically to robots or geeks (unless you count Bender's "Robonukkah," which some fans have placed in February and which I'll be sure to bring up around then, possibly with fembots wrestling in petroleum oil.)  So wired.com honored the long list of Scottish inventors in today's "This Day in Tech."

Of special note for hackers/open sourcers is this entry (directly quoted from article):

A stumbling bumbling attempt at a 3D printer

Well this is my attempt a building a 3d printer, I am blaming TinHead for the whole thing, perhaps with some blame beeing focused on CtC as well and let me state here Chris and Tinhead were both a great source of encouragement and help in this on going project. The whole journey started with my seeing Tinheads build of bumble bee  http://letsmakerobots.com/node/32879
