Diy self balancing robot arduino based.

[@akirahonda7356]

Congrats!! One of the best projects in the web. My graduation project was a self balancing cart. It was 1989. It doesn't work. There were not so many ready made circuits like Arduino. You showed times have changed.

[@leobrunotronico]

Finally I managed to successfully implement this robot, congratulations to the author! I had difficulty understanding the PID adjustment, but in the end, after many tests, I realized that it would not be necessary to change any of the data reported (based on the video values) the critical point, in my case, was to leave the resolution of the step in eighth step (only ms1 and ms2 connected in 5V and ms3 floating), with the sixteenth step the robot was able to balance itself but it was not in a fixed position, it made an oscillation amplitude of about 40 cm. It was necessary to change the transmission rate of the HC-05 to 115200 by AT commands, but it was fine. To make the cursor go back to the center in the app: settings => check the "back to MID" fields. Do not forget to use an electrolytic capacitor (100 uF or more) between the Vmot and GND pins of the A4988 driver, unfortunately, during the tests, some were burned because I did not use this capacitor. Any questions I will be happy to help you.

[@bergamt]

Try putting the battery on the top level. With an inverted pendulum, a higher center of gravity actually makes it easier to balance.

[@dozog]

Looking through the comments to find if anyone else would say that. It is counter intuitive, but it is true. As i have said below similar videos : Try balancing a broom on your hand. First with the brush side up, then with the brush side down.

[@oluwaferanmi100]

@@dozog While I was also building something like this, I found out that although having a high cog reduces your angular acceleration ( ~ -g/L * theta if linearized), having a cog closer to the axis of the motors actually causes the robot to sort of stay upright even without controlling it, at least this was what I experienced in my case. I guess this happened because now that the cog is lower, the restoring torque from the robot tends to make it upright rather than make it fall. In the end, we can't really achieve that much low cog so just raising it as high as possible is the feasible option.

[@dozog]

@@oluwaferanmi100 Isn't that the difference between static stability and dynamic stability?

[@BikermanCoUk]

Hi, I'm in the middle of building this robot and I have a question. I'm building without the custom PCB (ie on normal breadboard), so I'm using your diagram. It all seems OK except for one connection. On the top A4988 stepper driver the ground pins are connected through a 1K resistor to the step pin and to D5 on the arduino. This seems wrong - I would have thought that the two ground pins should connect directly to ground, with the step pin connected to D5 and a 1K bridge to ground (ie the same as the bottom A4988 driver). Have I misunderstood the circuit, or is it just a misprint ?

[@AntiDarkNet]

I am two years too late to reply, but the STEP pin is connected to D5 and the same pin is pulled down to GND by the 1K resistor. Same happens in the bottom A4988.

[@zohairajmal]

You need to set your HC-05 bout rate to 115200 first, for this you need to set it by AT command mode

Hi Mr innovative. I have ordered the pcb’s from the link you provided. I got them and installed the components as you suggested. But there is a problem. I burnt 6 arduino nanos.

Mr Innovative. It turns out the Gerber file you share on your link has a short circuit on the +5V and the ground as well as PIN no 9 on arduino which burnt out 6 of my Arduino's!.
