HAPPY DASHAIN LMR!

Today marks the first day of the biggest festival in Nepal - Dashain. It also marks the first time I'm wishing a Happy Dashain to LMR!

Sunny - The InMoov clone at DFRobot

UPDATE OCTOBER 24, 2014:

The time lapse video made with 1200 photos captured by Sunny's camera eye (it's on Youku).

May I introduce Sunny. He's a direct offspring of the famous InMoov.

Sneak preview - Yet robot related

UPDATE SEP. 24:

Now it's robot related, as you can see on the following photos.

DISCLAIMER: No robot was harmed during that photo shooting!

Alexandra with the HCR.

And Alexandra as a brain surgeon trying to rescue the InMoov we just started to build.

At Startup Weekend, Everyone is a Winner

What do you do if you manage to get the approval of 4 out of around 60 people, to work on your idea for the next 54 hours? Sadly, you don't make the cut but then you look around, find someone passionate about their idea - someone who's willing to take a risk by picking YOU to be a part of their team - and start working on it.

Making a hand for the BRP

This started as most of my designs as a napkin drawing, then looking at the materials on-hand and then off to the milling machine. 3D printing would never work for me as I make and design rather than design and make.... I blame legos....

Extra Hardware Needed for Larger Hexapod

About a month ago I purchased hexapod kit off ebay.

Aluminium-Hexapod-Spider-Six-3DOF-Legs-Robot-Frame-Kit-for-Arduino

Yesterday as a break from program my Mini Hexapod, I started putting together this larger one.

ROBOT ARTIFICIAL INTELLIGENCE OPERATION SYSTEM

I am writing an OS for my future robots. So far the system is more or less a simple CAS (Computer Algebra System). The idea is that not only the user can use the CAS, but also the robot itself. It can solve linear and quadratic equations, includes linear regressions and a simple scientific calculator. The standard order of operations (1. exponents and roots, 2. multiplication and division, 3. addition and subtraction) is used. For the equation string parser I conceived a simple algorithm.The string will be simplified till only addition is left. Example:

Sunny - failed blog post

May I introduce Sunny. He's a direct offspring of the famous InMoov.

We started building Sunny (well, I am actually not doing much work but giving a helping hand and advises) her ein DFRobot for display at the Shanghai Maker Carnival in mid October.

Right now the head is almost done and we are planning to move down step by step.

The head contains a camera and a speaker to stream video from his left eye and talking via a Python script Espeak running on a Cubieboard.

The beauty and the beast - the magical conversion of a gun

I have not posted any robot in ages but I am still doing stuff :-)

For a project I have in mind I made and purchased some gadgets, also this Nerf gun

Unboxing the Robox

I did have time to unbox this, but I didn't have the time to actually use it or even to clear a spot for it. That's for Wednesday when I eventually wake up again. The Unboxing was easy and it all seems ready to work once I read the instructions and remove various pieces of packing tape and such.

My 3d Printer has Arrived!

Many months ago I found a 3d printer in Kickstarter that looked like a good combination of ability and cost. This was the Robox. And like most complicated Kickstarter campaigns they were late. So I waited and waited until this morning when I got the call!

Hopefully sometime this afternoon I will get my shiny new printer and be able to print robot parts. They should also be sending some filament, hopefully in the same box. Otherwise I won't be able to print anything until I get some. Maybe today I can place an order from Taulman for some nylon.

Gee Thanks, Google...

I went to Google looking for an image of a particular kind of diagram to use as an example for the flow of a process I was working on today.  It took me a few minutes to figure out what was going on:

Not what I had in mind.

(this was NOT the kind of "State Table" I had in mind, but now I have to make one of Iowa to keep in my cubicle.)

ST Nucleo F411RE upgrade for Blizzard Bot

Aug 31, 2014

For ten dollars and change from Mouser, I can't resist. The 24MHz STM32Discovery board now in use is getting the boot to be replaced with a ST Nucleo F411RE.

An added bonus is the access to the mbed.org development environment.

Features

what is needed for an animated biped robot

For my project (http://letsmakerobots.com/blog/carloroosen/pet-work-progress) I need complex behavior and nice animation. My example is the NAO robot (http://www.aldebaran.com/en).

One of the things I am thinking of is mixing animation layers. Say you have one animation layer that does a basic biped walk. And another layer contains a balancing correction. And a third layer might contain head movement. Let's call them A, B and C.

Capturing Data from 7-Segment Display

Something I've wanted to do for a while is to be able to digitize the data from cheap sensors with a 7-segment display.

I decided to give it a try with some USB charge meters.

I purchased four of these meters.

I opened up one of the blue ones and probed the pins to see how the 7-segments were wired.

Pet (work in progress)

I have not built my first robot yet - waiting for the parts. But I have the plans for my second robot ready. He, just a little ambition :D.  My second project will be a prototype for a robot that can be sold as a consumer robot. I will call it Pet - working title.

This is how I imagine it. When you order Pet, it will come in a nicely designed box. In that box you will find a shiny sphere, a little smaller than a soccer ball. One size of the ball will be flat. You will also find a smaller box that contains a base plate with an electrical cable. No on/off switch. No manual.

Raspberry Pi Model B+ Review posted

Sorry guys, I forgot to mention it earlier!

As you probably know, the Raspberry Pi Foundation brought out the new Raspberry Pi Model B+ recently.

I got my hands on it mid-July, and after torture testing it wrote a rather large review.
