Misc / Hello from Brisbane Australia looking to connect with locals
« Last post by galderdi on August 26, 2021, 06:32:44 PM »

As per the subject I am in Brisbane / SE QLD.

I have almost no experience with robotics but I am keen to get involved.
I do have experience with electronics, electrics and some grass roots (unqualified) engineering. I have previously built 2 Electric Vehicles and I am currently part way through my third EV.

I am looking to connect with locals robotics enthusiasts. Partly to expand my knowledge and experience but mostly to apply my existing skills and knowledge to augment existing projects. Please respond and let me know if there is a local group worth exploring. 
Mechanics and Construction / Toy applications, making YOU money!

 ;D  excelsior!   ;D

   Hello, robot superheros!!   8)

   I have had friends to help me explore the new applications of the robot toy I
am working on, and found out some business applications, which may help
a robotic superhero to make money at his hobby, especially with my toy!

   I had a friend who owns a local, small seasonal Halloween "theme" park. He needed some
attractions to spice up his park. Just by luck, I found a horror artist who has great ideas for
attractions, but can not make them.  :'( And so, there appeared an opportunity!  ;)

    I got to work with the artist to use the robotic boards to make his creations, which could be
rented at the theme park; so we would both make money!! Great, right?   ;)  gets better!!   :o

     I found a company called Horror Dome, which sells attractions for horror theme parks. The
selling prices are 10 to 30 times the cost of making the attractions, AND, they sell worldwide!!   $$$!

    Moral of the story is this: Take your own Axon or raspberry pi to create a horror attraction, then
test the "sellability" of the illusion on an audience in a local theme park; if it is a best seller, you can patent it and sell
it on Horror Dome, and have the potential to become rich!!!!!!!   ;D ;D ;D

   And there you have it, a practical reason to use your robotic superhero powers to keep on making
robots!!!   ;D

     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.   ;D

  ;D see you same robot time, same robot channel!   ;D
Mechanics and Construction / New Humanoid Robot Project!

Hello, I have started a full scale humanoid robot project. Check out the progress, I am currently finishing a leg to begin working on the sensors and electronics. I will be using brushless DC motors, MPU6050 and ultrasonic sonar sensors. I am printing the parts on an Ender 3.

 :) excelsior!!   :)

   Hello, True Believers!  8)

   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!!!  ;D

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

     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  8) 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!!!   ;D

 Thank you for reading this post!!  8) see you next  post, same robot channel, same robot time!!!!   8)

 8) excelsior!   8)

I would like to recommend a book that will help you with my new robotic toy!

 "Beginning Robotics with Raspberry pi and Ardunio"

This book gives a quick reference to all the main points that will make your
life easier with robotics, especially with my toy!!

 ;D see you same robotic channel, same robotic time!!!!  ;D

  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.  8)

    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   :)
