Let's Make Robots!



Not many people understand chronic depression. I doubt anything I write here will solve anything, but I think it's important that people recognize the signs of depression and learn to recognize them in themselves and their loved ones.

Most people make the mistake of confusing depression with depression. See, I've just done it myself. One problem for English speakers is that the word for depression (as in a chronic life-threatening mental illness, most often inherited) with depression (as in being sad for a few weeks due to a known cause).

The Beginning

Working on finding a working set of componets to build a remote controlled, tracker, / object avoidance robot in one package. So far the 4 wheel drive Chassis, Mega2560-16AU R3 Board, L298N DC Driver board, several HC-SR04 sensor mods, Jumpers, have been ordered.

Dawn of a New Era

Well after many years, aproximately 14 to be correct, I am venturing back into the world of Hobby Electronics and Robotics. I have always been interested but over the past 14 years have focused on technolgy and computing rather than Robotics (not enough time for all the hobbies that I would like).


the BoBs that never were

been a bit since ive posted anything besides talk in the shout box. now that my kossel is well on its way to completion and still seeing all these cool BoBs and variants out there. i figured i could put some of my old designs to use. i pulled up my old dropbox file and remembered all those projects i started. and thought i would share some of my insane designs. these are the BoBs that never made it off the computer screen. links are to dropbox folders cant embed from drop box (to my knowledge) and im too lazy to sort them and put them on photobucket!

Insectbot Hexa

Later than expected but finally finished. The Insectbot Hexa is an advanced offspring of the already aging Insectbot Mini. Build with parts of dead insectbots the Insectbot Hexa was born, with more legs, more sensors and new power source,

I will do a detailed tutorial with lots of pictures later but for now I do have that one and a video.

As the video embedding is not working, here comes the link: Insectbot Hexa

Heated Bed Warning Light

Hello everyone, I thought I'd share a circuit I am using on a little 3D printer upgrade project.

I have a heated bed PCB for my Printrbot that I am currently adding to the underside my aluminum bed. I needed clips to hold the pcb in place and provide a housing for wire strain relief. I designed some and printed them out. I wanted to add LED warning lights to the clips so they would glow when the bed was hot. I really wanted the lights to stay lit after the bed was off and slowly dim to nothing over about an hours time like the warning light on my stove does.

For those playing along at home , here is the recipe for the video above :-

YANBO's on hold for now...

Thinking outside the box(es) requires one to identify and solve the real problem. "You've got to free your mind instead..."

DreamMaker Overlord sneak preview

Well, it's time to inform you that the DreamMaker Overlord is launching on Kickstarter soon. 

UPDATE: Launch time is confirmed. It's 00:00h CST. For less confusion I did list some major cities here: 


My little machine shop

For too long, my machine tools have taken a corner of my garage, with no heated home of their own. Living where I live, that means suffering thru cold to do any work, as its seems to be cold here 9 months of the year. This fall I decided to do something about it and built my own little shop area in my garage, leaving room still for all my junk and to park my GT, or two really small cars.

Humanoid Robot PIXEL

Pixel is a Humanoid Robot 8 servo motors and 6 DC motors give it high degree of freedom, running on Arduino board it can be controlled by an Android phone or a windows PC via Bluetooth by Android app designed for it or a Matlab GUI designed in PC. An On board camera in head of the robot is used for surveillance .Here are some pics and videos of the Robot. http://gronixindia.blogspot.in

Virtual InMoov gets "Potted" by Prop & Atmel Mega

It was quite a work to "Rigg" the file of InMoov that Gael sent me.... Its feasible, and the speed is good.

So far I have only automated the fingers , arm, and shoulder joint.

...and now that I can understand the mechanisms .... next job is to add some bones to make pose_ing easier (in the blender environment).

The Potentiometers work well with Blender via a Parallax Propeller comm link.....

Parents & Children = Virtual Robot Arm

Have Just configured 4 Potentiometers to contol my Blender Virtual Robot Arm.. Using a Propeller to TX four Analogs over a Serial link. Using Python code to control the actuators.

Each arm part is parented to next in the chain , meaning that they are all connected as one limb however able to turn on its parents axis.

Will Code For Parts

Yesterday I received a bunch of really nice robot parts from Parallax.

While I didn't purchase these parts, they're also not really a gift.

Parallax wants some Spin code modified to work with some of their new hardware. I've been sent this hardware with the expectation I'll get the code working with it.

Virtual "InMoov" controlled with Hacked Positional Servo

Video Preview using PySerial with Blender.... Walk_through pending...

This is the Nomad 4WD Off-Road Chassis kit! 

And it lives again!

The Robox, thanks to tech support, lives again.

I think I may have messed up the bed though, because there are some parts that seem to have bad adhesion for both ABS and PLA. I'm printing a case for my RasPi B+, but I'm leaving it to go because it's on layer 7 of 91 and it's after midnight. If the case prints nicely, I'll try to make some levels for mini-Groucho who is made of OpenBeams and I'm hoping to make the levels and attachments by printing them with Titon nylon.

Some of the levels are easy, but I'm hoping to build the motor mounts into the bottom level...

Lights on Bikes!

Hello LMRians.

In rememberance of Late Dr. Prahlad Yonzon, a Nepali biologist, Cycle City Nepal 2020 organized "Critical Mass", a  cycle rally. Dr. Yonzon, although having spent his career largely in the science field, was also an avid lover of cycling. Sadly, in 2011, he was hit by a vehicle while cycling, and died while undergoing treatment. 

And now the Robox is dead...

After my first print, where the filament had already been in the printer for about 2+ days, I left it it there for another couple. By this time the filament was stuck firmly into the printer. I did get some back, but pulling a bit mor firmly than I should have resulting in the end of the filament coming off (nice clean break) but with some left in the printer.

So now I can't do any further experiments with the printer, and I am screwed until I can get that last bit out.

Any hints will be appreciated because I'm about to open it up by throwing it against the wall a few times.


The Robox Liiiiiiives!

My 3d printer has printed its first "Hello World" glob of plastic. OK, it's a pyramid in draft format, and not particularly good at that. However, the PC finally recognized the printer and everything sort of worked.

I repeat, this was in Draft format. I will do more interesting things later

Qonix - Lipo Blue smoked

Thought I would just document this as a warning to others who want to replace Lipos in consumer products.

All is not what it seems........

For a while now my Cheapish Qonix Portable DVD players battery was not lasting a whole Film.

So I looked inside and found a 2cell Lipo battery within...

I bought an equivalent 2 cell and proceeded to plug it in.......

Durga Puja

This isn't robot related at all. Pardon me if I have chosen the wrong place to post this.

Durga Puja, or the worshipping of Goddess Durga, is the greatest festival of Bengal, the place where I live in. See what Wiki has to say about it here.


CCSR updates

Hex Caster

Hex Caster is my attempt to come up with some play on the word "hex".

I plan to use this PCB with both my hexapod projects.

Here's the top of the board.

Below is the bottom.

The servo banks are broken into groups of six.

Clever f*ckers...

I've never been a fan of the "Turing Test" as a measure of machine intelligence-rather I think it exposes stupidity in humans.  The recent victory of Eugene Goostman over the actor who played "Kryten" in Red Dwarf and Lord Sharkey says more about the people that the Royal Society thinks are qualified for this kind of science than it does about the programming of intelligent machines.

Mechanical Thoughts


     First of all... this blog has been inspired by this thread.

     Here I'll post things that will never be a project in fact and I simply consider it interesting, or is still far from being a project.

     I hope to share ideas and I also accept suggestions.


Automatic medical diagnosis device - Part 1

One of my long term projects is to develope an automatic medical diagnosis device. During my research I came up with the so called naive Bayes classifier and started to learn about this kind of machine learning. In the attached PDF I use the example given on the wikipedia page but in greater details. If you want to learn more about naive Bayes classifier, I recommend the following one: http://guidetodatamining.com/guide/ch6/DataMining-ch6.pdf
