     Hello robot superheros!!

     In my plight for using stepper motors for "relative" precision required for my robot,
I have decided to try to use the Easy Driver stepper motor driver. With just a few pins from
the raspberry pi, you will be able to control 2 stepper motors with enough accuracy to
use the robot effectively.
    I wanted to use the adafruit stepper motor hat, BUT, you have to download the library
and use their code; not bad, but will stray away from true python programming. I would like
to keep the programming language as pure as possible, without getting entangled with other
languages that might not even be in existence in 3 years, not to mention the stepper hat might
not even be available. 
    I would like to keep this robot working for the long term, in which more applications can be
intuitively installed without involving a convoluted mess of languages, which only serve to
kill the learning curve and progress of the robot. 
   You will always have the option to use other languages as add ons to your own apps, but the
basic cores (I think) should be a pure building block that can serve the future as well as
retro apps. 
   I have attached the picture of the servo controller, in which I have heard good things about.
I am going back to the drawing board to accommodate these drivers, which will involve some
soldering skills, BUT, will be worth in the future, for simplicity of diagnostic and control.   

  see you same robot time, same robot channel!

   Hello, True Believers! 

   In my preparations to make this project as simple as possible, I
have found a company that sells the raspberry pi, the LCD screen, camera, AND freeware already installed!!! 

     All you have to do, is build the mechanical, load my control program, and VOLIA! instant robot toy!!!   

     I had to do it this way, to simplify the programming issues that (believe me) would frustrate anyone. Loading
and compiling some of the freeware can be a task, and could take away from enjoying the robot. 

     Although, slugging through these issues is what robotic  superheros do; but, that is one less thing you will
need to do.

     I am working with the company to make sure it works properly; if so, this will simplify the project greatly, and
reduce the cost of the project by approx $50 - $100 dollars!!!   

 Thank you for reading this post!!  see you next  post, same robot channel, same robot time!!!!   

  excelsior!   

  I see you added another video on to your original one - about using global variables exclusively.
When I am making small programs, making all variables global can be a great help. But, when my
program starts getting large, I find I must enclose local variables to functions, to keep from overwriting
other information on other variables. I used them so much, I have a variable overload, which wrote into a memory block in which it was not supposed to; and crashed my computer.
   Having learned that lesson, I got an experience of why functions are important, besides being cool. 

    So, there you have it!!

    If you want really powerful code, with very little statements, try FORTH. It is challenging, and not many programmers use it today. It is used in all the cool space stuff, so have a look at it!!

   good luck   

Greetings, I have been working a lot on my new robot project. Today I discuss the electronics. I will be using a lot of MPU6050 gyroscopes. I discuss a scheme to control up to x16 MPU6050 modules with a single Arduino.

     Hello again!

     In reference to your high level language, may I humbly suggest Python?
Reason being, Python is "bound" to about every language there is, and
a language that you use on you robot would set the stage for other
people to access and build a robot like yours in a friendly, familiar
platform.
    This would allow you to access other resources as your robot project grows!   

   Good luck!
