3D model description

Robot dog, inspired by Boston Dynamic's "Big Dog". Its powered by 12 high torque servo motors, very simple for printing and assembling.

Its powered by 12pcs of MG996R servo motors. Im recomending using 6v for powering them for higher torque and better speed. Save pulleys (little black round pieces which comes onto shaft of motor) from motor because you gonna need them in assembly.

Also, you would need 4pcs of 6002RS ball bearing for shoulders and some m4 screws for body.

In name of all .stl parts its written how many pieces you need to print. Its self explanatory position of printing parts, and on upper body and shoulders i added custom support which you should break after printing.

You can use PLA plastic, and dont need any supporting material. Anywhere where support is needed, i embeded it into model.

For more details about assembly, check out pictures and whole robot STL.

I used A+B glue to fix motor pulleys onto printed parts, but im recomending using some short screws for plastic, since later you can take them off and adjust angles.

all motors are 180 degrees, and by default, everything is mounted when they are in middle (90 degrees)

Unfortunately, my knowledge of coding is bit limited , but i will certanly try to program arduino for this. Im recomending Arduino Mega, since it have enough pwm pins to support all servo motors.

If anyone feel capable of programming this thing, go ahead, i can give him/her credit for it here :) Its nice challange :)

Je relève le défi. J'ai imprimé le projet. Tout s'assemble bien et je conseille de prendre un esp32 (16 PWM) comme carte de commande.
Mais le code est sous Arduino et donc comptatible avec l'Arduino Mega avec quelques modifications.
Mes premiers essais montrent une très bonne synchronicité des 12 moteurs avec de la rapidité et de la fluidité dans les mouvements lents.
J'ai écrit un programme pour PC sous windows en visual C# pour piloter les moteurs et enregistrer des trames pour lui faire faire tout ce que l'on veut.
Des photos du make et des programmes bientôt .
