Tell us about yourself!
Thanks, and how does it looks now? I have nothing to do with Russia but I like to use this vintage Chernobyl look....
Very nice little project, easy to build, very nice sounds. I built it in a breadboard now it goes to a metal box with a vintage look.
Hi John, thanks for the advice, my little machine is now working. You may thanks to Arduino Facebook page, there I found your project.
Thank you very much, I guess I'm not that lazy so I went to this link and now I'm going to try with this.
Hello John, so nice and lovely sounds... maybe I like them because my age... don't ask. I want to try this project but I don't have logarithmic potentiometers. Can I use linear pots while ordering the other ones? what would be the difference in the sound? Thank in advance.

Thanks, I Will give it a try.
I sent you a message with the link to my design more like the original MIT Cheetah, please check your private messages.
Thanks again, later I will send you a link to my design in Tinkercad.
Thanks again for your answe. I Will need to find another way to calculate those numbers, I don´t know trigonometry or there is a simple formula to do it?. What I still don't understand is the way the program uses these numbers to move the servos. I guess there numbers are angles but why are they grouped between brackets. Why the servos moves so smoothly.
I'm trying to understand how does your code Works in order to change it to fit my legs design but I still can't. Can you explain it in simple words?. I guess the position for the servos are in these walkF and walkB arrays.
Thanks, I know how much the original servo cost, that's why I use this US$ 7 servos from aliexpress. https://es.aliexpress.com/item/724946838.html?spm=a219c.12010612.8148356.2.56d08f4ahVfLYG
This the way you connect PCA9685 to an Arduino. 5 volts power supply goes to the module. You can also use an Arduino nano to the same I2c pins A4, A5.
PCA9685 weight is only 9 grams. Sooner or later you are going to need bigger servos. I'm working in a leg design more like the original MIT cheetah with thos 15kg servos. I Will try it with your program but sure I Will need to change the angles for the second servo.
Hi Again Do you know you can control up to 16 servos with the two I2C Arduino pins ? Search for this PCA9685 module. You can also Daisy chain a lot of them for more servos.
Baby MIT Cheetah Robot
Hello:This is quite intesting. Long time ago I made this version of a Cheetah robot inspired in a design from the Ecole Polytechnique Federale De Lausanne. My starting point was only a drawing and I made at that time a wooden version. I'm not good programing so it was not able to walk properly, I choose the wrong pase pattern, then a abandoned the project. Now I'm very interested in this project. I may wait for your second version before start building my own cheetah. Attached a photo of my cheetah.
This is short video testing the robot, you can see that is very erratic, The original robot moves opposite legs by the corner at the same time. I guess I give up with the programing to son. https://youtu.be/f15e_QD7sKs
As I told you this is not my design, for me is very easy to mimic any design just looking at a photo or a drawing. This is made out of 3mm MDF, now I can cut aluminum with my self made CNC router. Servos are RDS115mg, a robotic servo from aliexpress, they come with an aluminum horn and braquets. This the link to the original design https://www.popsci.com/science/article/2013-06/robot-runs-cat/
Thank you very much for your answer… you are rigth, a Raspberry Zero W is on my way…
Hello, I just jump on this reading the last issue of the HackSpace magazine. Very nice projet. I haven't study the codes or the Drum sequencer, I will, but I'm not good programing anyway so I have a question: Do you think if it is possible tu run this on an ESP8266 or an ESP32? Thank in advance.

Thanks, I didn't think to give them as a gift, I just added a new photo using the ornaments on bamboo sticks.

Hi Michalis:Do you think this code will work for a NodeMCU ESP8266 board?
