 8)  excelsior!!!   8)

   Interesting video, very nice. Gyroscopes are important to the robot walking, no doubt.
I would venture a suggestion about looking into other raspberry pi products that already
use a gyroscopic module, but without the actual physical structure.

    Keep up the good videos!!!   ;D

Electronics / New Humanoid robot project update - cloning Atlas
« Last post by Diorthotis on July 13, 2021, 09:37:56 AM »
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.

You need a sufficiently large capacitor across the power rails. It will provide a boost of power when the motor starts. You also need a back-emf schottky diode also across the power rails, but in reverse polarity.

 8)  Excelsior!!   8)

     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!    :)

Thank you! I took a lot of time to make things really clear. Now I'm trying to figure out what to make next. I was considering trying to develop a high level language and compiler so that it would be easier to program the robot. I don't know very much about that, but it seems like it would be fun.

 8) Totally Awesome!!   8)

     I love the "pet on the chip" vernacular!!! how about chippett? or petrick?
Just some work play on your project statement.

    your documentation is awesome, and very precise. I love reading the manuals,
and seeing where it all fits in.

    Awesome job!!!   ;D

Thank you! I have a short video clip of it running here (at the end of the article): https://ezrasrobots.wordpress.com/2016/12/03/the-robot-pet/

I also have a new version here, called Pet on a Chip, where I condense all of the control logic and a custom CPU onto an FPGA: https://ezrasrobots.wordpress.com/2021/07/07/pet-on-a-chip/

Mechanics and Construction / Re: Desperately need HELP on gearing !
« Last post by mklrobo on July 07, 2021, 12:50:30 PM »
 :) hello!  :)

  In your gear dilemma, you will need to consider TORQUE, a measure of strength of pull. If you
"gear down" a motor, the torque will increase, but the speed decreases. If you "gear up"
a motor, the torque will decrease, and the speed will increase; assuming the motor parameters
stay constant. This is not rocket science, but attention to detail is required.
There may be MANY gear calculators online, for sure. The trick, again, is to recognize
the power/speed that you want to work with.
    I would recommend getting your speeds and torques done with a online calculator, then
you can see what is available from stores.

 ;D  Good Luck!   ;D

 8)  EXCELSIOR!!   8)

   Good day, True robotic believers!!

    I would introduce to you, a helping hand in writing your python scripts;

     https://streamlit.io   ;)

    streamlit program will help you write your python programs; which will be useful when you
hack my robot program when I release it. This program is free, but, as all software, will cost
you time in learning to use it.

    Another program, which is a starting point for cross platform programming is:

    http://www.flowgorithm.org  ;)

   This software gives you a basic, bare bones skeleton of cross platform programming. Not the best
of programs, but is a nice intro to information of cross platform programming.  This will help in your
desire to let your smart phone access the robot, for remote control, camera pics, software uploads, or
additions of IoT peripherals that you can imagine!!  ;D

    As to the main core of the freeware used, I will submit communities that focus more on the internals;
so you can go as far as you want to to accelerate your imagination on the robot!!   :)


    I will release more freeware advice that is helpful, for future concerns. So, when you get the
robot plans, you will already have supplemental info  to hack the robot!!   ;D

    Thanks for reading my post, and stay tuned, same robot channel, same robot time!!!   ;D

Thanks for the reply my friend, and thank you for the time u dedicate to see the link.
I will consider your suggestions and I will let u know what happened :) thanks  ;)
