Let's Make Robots!

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

Campus Party London 2013

UPDATE SEPTEMBER  8:

Well, it's a couple of days now that the Campus Party closed it's doors and I am back home already. 

Service Droid

Working for DAGU means I need to try and design products that are not just cool to look at or play with but are also affordable and easy to use for the beginer. Sadly this balance is not easy to acheive. Usually more fun / cool functions means more complexity and cost.

Desk Robot; An attempt at planning.

Biped Howto: Inverse kinematics

+++ UPDATE (12-march-2014): Rename title as "Biped Howto".

Hello all!

This is D. Jay Newman, also known as Dangerous Thing (as in "A little learning is a dangerous thing.")

I built several robots in from the late 1990's through the early 2000's. I had several articles and one book, Linux Robotics, published. Then my wife became extremely sick and I had to quit work to become her full-time caregiver. I was also forced to quit working on robots. Lately I realized I had to build things again or not be true to myself.

I've begun working on the troupe: Groucho, Harpo, Zeppo, and eventually Chico.
