    Self-Balancing PT (homemade Segway)

    helloyou have the program the MCU at least once with the program and maybe more for PID gain tuning. They are dependant to the mechanicla proprities of you construction.

    le MPU fait des interrruptions hardware periodique,ligne 82 de SelfBalancing PT.ino.le calcul du PID se trouve à la ligne 60 du fichier controller.cppligne 80 est le traitement du calcul PID selon l'etat.control de moteur par el Sabertooth de la ligne 110 à 174Le lien dessous est un bon tutoriel de PID.http://ozzmaker.com/success-with-a-balancing-robot...

    Self-Balancing PT (homemade Segway)

    comme j ai deja ecrit, il faut une base en electronique et programmation.As tu deja fait un essai/tutorial avec un arduino? Essayé de communiquer avec le module MPU050 par I2C?

    bonsoir GhEn effet, je comprend le français. Ai-je dèja répondu en francais sur ce site?Dis moi plus précisement ce que tu as deja fait et voudrais savoir. Ca sera plus facile de te guider.Adrian

    hi BillNice project!Nope, I never had problem with the MPU-6050 / GY-521 break-out boards. This board has his own suppy regulator, it muss be supply with 5V. Just the logic signals (SCL and SDA could be shifted to 3.3v. The arduino input is 3.3v compatible.regardsAdrian

    Dear readersHere an update after a few month of trial and testing.- The mechanics, motors and power electronics work like a charm.- The balancing algorithm is limited when the motor reach ismaximum speed. Pretty simple to understand: if you lean forward or backward,the speed has to be increased to compensated, but if the motor is already amax, it is not possible anymore, so you fall! I was aware of that and withoutknowing the motor speed, it is always a guest if I can still lean or not.Therefore, I added a buzzer (or a vibration motor) in the handle activated by the ARDUINO when the motor speed isover 90%.- It happened a few time that my ARDUINO NANO had to be reprogrammedbecause it lost his program!. This happens when the motors regenerate currentwhile driving down a hill.I would say t...
