New Job

I recently acquired a job at a local ROBOTICS company! I am doing light assembly work for now, but it will get more involved the more experience I gain. Wow, I haven't posted for a while.

I haven't been able to get much work done and my projects, been really busy with other projects (more important ones)...

It has been a long time...

Yesterday I got my robot's wheels turning. Now I am working my way through the programming of the driver software and the ultrasonic range finder. After I do a little more mounting my robot will be complete (Took me long enough :) )...

I might post some images to my blog (http://briansrobotics.blogspot.com)

In other news I have recently created a SourceForge project. It's called Getix (dx-voice-conf). Getix uses Direct X extensions for voice conferencing. The goal of this project is to create a program (for Windows) that will allow lobbiable multi-user voice conferencing over LAN or the Internet.

You can check it out at https://sourceforge.net/projects/dx-voice-conf/ and the project HomePage at http://dx-voice-conf.sourceforge.net/

Some Good News, Some Bad...

Well, I have not updated in a while, so I figured I would fill you all in…

Today I received a letter from a school district in California telling me that I have officially passed the NASA Ames robotics course I took this summer. That was some good news! I have finished the control system for my robot, but was having some problems with it, so I broke it down and am working from the ground up, trying to find what is wrong. Unfortunately I do not have an oscilloscope to read the waveforms. I am going to try to get that working, and then I‛TM]ll be in good shape!

More Control...



Well, I finally finished the conrtol board for my robot, I
am getting ready to plug it all in and test it. I have some
pictures on my blog (briansrobotics.blogspot.com) if
you want to check it out...

The Rise of BriOS, Mr. Gates, be very afraid!

I am sure all of you are wondering why I have not posted in a while. Well, I have been playing around with Operating System Development. It is very fun stuff!

Right now I am doing a pure Assembly OS. I have my OS based off of the EasyOS structure. I have been able to accomplish some basic command line instructions. Right now I am developing a simple GUI structure to operate on…

More control...

I have made soe progress on my robot's control system, I have a picture and more details on my blog briansrobotics.blogspot.com...

Going in Deeper...

If any of you were wondering why I wasn't updating, it was because I was on vacation. But now I am back, so on with the updates.

Recently I have decided do go deeper with my voice recognition journey. Instead of using the Microsoft speech SDK, I am going to be developing my own Speech Recognition engine. My reason for doing this is although the MS Speech SDK is nice, it doesn't provide the accuracy that I am looking for.

I know, this seems as if it would be impossible, but I have worked it down to a science. The way I will attempt to do this is I will have my Microphone input stream inputting to an array of numbers, then I will compare that array to another array for specific commands.

If you are asking how this will be more accurate, then I shall explain. The original arrays that I will be comparing against is the specific words, spoken by me, so the input and the comparing arrays for specific words will be extremely close already, also I won't have millions of other words that the engine is trying to match the input against. Only the ones that I setup.

Right now I am leaning towards using the DirectX Voice input libraries as my voice command input stream. By if I can find something more efficient, then I go for that.

Code Clean-Up

Well, I am planning on cleaning up my Voice Recongnition / Serial Device Command program today, so that it flows a little faster.
More waiting....

Well, as of right now I am doing some more waiting for parts. I found out that I needed a different solution for mounting and connecting up my StampStack 2 module. My Options now are getting an IC socket for the PIC16c57A inside the StampStack and also getting a 20Mhz Resonator to go with it, or I could get a PC Board that would fit the StampStack. I want to go with the socket/resonator approach because that would cost less on the long run and my processor unit's for my robots would be smaller...
