Robot Test Facilities Have Been Provided...

Holy Geeze,

Did you guys know that there are places to do robot testing on just about every corner? They are all identical (everywhere) and can be counted on for solid, non-changing environments. They go by many names:

Robogames Photos

I have uploaded all my photos to my facebook page.  They should be available for everyone to view.  There are just too many to add manually on this site.  If you have troubles viewing them let me know.




Processing talking Bluetooth

Getting Arduino talking through Bluetooth seems like an easy task. There are plenty of tutorials showing you how to do the initial setups and most Bluetooth modules have their own wiki pages + datasheets you can use. It works, you can make the connection, use a terminal software, send packets back and forth. It's all good. Or is it ?


Possible AGV

So I came across patrick's agv (http://letsmakerobots.com/node/18922) and his tutorial (http://letsmakerobots.com/node/19554.) and I remembered that I have a nice rc car. Once I learn more about robotics, I plan to build an Automated guided vehicel with the same compass and gps. Is this a hard build? 


Here is a video that I took of the rc car

The most advanced amateur humanoid robot project


This is the MAAHR project. MAAHR stands for Most Advanced Amateur Humanoid Robot. The goal is to design, build and program a robot which is similar sophisticated as ASIMO. The project is completely open source, everybody can participate. I'll sponsor MAAHR with 15000USD for hard-, software and logistic.

MAAHR's specifications so far:



Bought one of these bad boys from -Adafruit- yesterday!

USB native hehe! but not here yet. (of couse used USPS first class)

need a bit o' help though. i want to get those .HEX files after Arduino compiles them. I am on a mac. where are those hex files?

tried searching  but, no luck probaly in .tmp folder :p.

Any help would appreciated!





Picture Time

Just some pictures from when I was getting ready for the games.  They officially start on Friday.  My teammate has gone to the event site for weigh in.  Enjoy

12v battery power and mega-servo conversion kits

Hey, I'm thinking of starting a real project this summer and I was looking for a few parts. The most complicated things I think I'll need to consider are the batteries and motors. For starters, I'm looking for a 12v battery that holds plenty of current. Something that could power a few windshield wiper motors for some time. Lithium cadmium looks interesting.. or I actually might end up using power tool batteries (just had the idea!)

Prop Palm

Man, I am a sucker for cool little plastic boxes...

So, Nick from Gadget Gangster posted a link to this guy over on facebook...

Right off the bat, I wanted one! Then of course, I had to check out the supply house for the enclosure. That was a bad idea and yes, I am building yet another controller for walter.

Off to robogames

Sitting here at the airport waiting for my flight. Just cleared security and customer with 4 robots in tote. Will have some pictures soon

iPhone as a robot controller made easy.

Just finished the vb.net app for controlling my robot with an iphone. It seems it is much easier than I thought.

The connection is based on Open Sound Control. The iphone sends special messages to my laptop via wi-fi.

More information on OSC. 



Mental vomit from an intoxicated robo-teer


My girlfriend successfully took me out and outdrank me tonight. Forget what that says about my manhood, here I am with something to say :hiccup: :)

Fourier Transforms

Fourier transforms convert complex signals into a series of sinusoid waves. Since it's easy to create a sine wave with a microcontroller, you can perform a Fourier transform on a complex wave and reproduce it with sine waves.  A few sine waves could be used to generate the sounds of instruments, and many lossy files like JPEG are compressed using DCT, a form of Fourier transform.

Got $1299,- to spare?

Then I would recomend that you have a look at the MakerBot Thing-O-Matic 3D printer http://www.makerbot.com/

With my 50 birthday coming up, my family chipped in and got me one of those fabulous machines. And I must admit that I’m totally blown away by the quality of the print and the robustness of the ABS plastic parts that is printed.

Review: Ro-Bot-X uServotino


Now, for the next in a series of reviews on Ro-Bot-X's boards. This one is on the beta version of the uServotino. It is an ATMEGA328 custom board with the Arduino bootloader pre-installed. 

The Kit

Ro-Bot-X's boards are usually available in three options.

Macintosh MacAXEpad Bug - "Hardware Not Found" when Programming Chip - how to fix

I just completed the basic construction of my Start Here robot and thought I would share something that drove me nuts. I searched and searched on this forum and couldn't find the answer to my problem. I found a solution burried on the Picaxe forum.

I was having the strangest problem. I could write out a simple little code and have the computer send it to the robot but when I tried to do more complex programs it would tell me that the hardware cannot be found.

Hobbybotics Reflow Controller

7 April 2011:

Wow, it has been ages since I actually posted something although I visit the site pretty much every day.  I ain't (good slang term) making no excuses but, okay, I am making some excuses as I am in the military and I do work roughy 11 hours, 5 days a week (when I'm not traveling).

Computer On Wheels Controller

Hi guys,
Since last week, I've been learning c++ and openFrameworks and creating a application to control any robot with a computer on it or, at least connected to one by someway.
It is supposed to be simple to implement and use.
You just need to run the application and program your robot to read the following chars and act corresponding to them:
  • 'w' to move forward;
  • 's' to mo

SI1120 Sensor working

Developed the code some more to determine which side and how far an object is. The green LEDs signify whether or not either side detects an object. The yellow LEDs signify which side the object is. Lastly the red LED indicates of the object is really close.



Weather station project: death, autopsy and resurrection

On April 2nd a bit after 11:33:22.546588 AM GMT+3 it happened. My weather station's (http://letsmakerobots.com/node/25773) remote unit died. I was having my morning coffee and noticed that weatherlogger hadn't received any updates for last 10 to 15 minutes or so. Last update was at previously mentioned timestamp.

Ro-Bot-X Board Reviews



Recently, Ro-Bot-X send me three boards to evaluate. I had previously ordered his Robot Builder's Shield V1, and commented with some constructive feedback and a review on it after using the board for Penny.

Robogames getting closer

The Robogames are coming up pretty soon.  Here is my team almost finished.  You can see Driller Shark on the left after the board and sensor overhaul.  The trusty Blaster Shark on the right.  And the new guy in the middle which still needs some stuff but is coming along.  That is all for now.

Chess Engine Update 4/3/11

Well by luck I happened to find some one elses chess robot in one of the instructables contest. He was using Apple script to communicate with a terminal chess engine. That is about as much as I read into his project when I was like "Apple script?"

Unable to C-code futaba RS301CR motors controlled by a pic 18F4520.

I've been trying to make a haptic glove controlled robot hand. The motors used to control the robot hand are Futaba RS301CR motors and are to be controlled using a pic.18F4520 . However my experience in coding is very limited, so i havent been able to figure the C code to initialize control for the motors.

motors: futaba RS301CR

 I have attached the datasheet for the motors. Would appreciate help with the coding or any other helpful information.

LM3914 Led mouth.

Hello everyone,

Here's a video of my led mouth I made for my "blue Freak Machine".

This is the circuit I made for it:


In my case the leds are numbered as follow:

8 6 4 2 0 0 2 4 6 8

9 7 5 3 1 1 3 5 7 9


Edit: Oops i mixed up the 3914 and the 3915.. they both will work anyways..
