Robotic Dog

cults3d

Robot dog inspired by Boston Dynamic's "Big Dog" is powered by 12 high torque servo motors. Printing and assembling are extremely simple. Twelve MG996R servo motors power the robot dog. Using a 6v power source will provide higher torque and better speed. Motor pulleys, which are small black round pieces attached to motor shafts, should be saved for assembly. Four 6002RS ball bearings and four m4 screws are required for shoulders and body assembly. STL parts indicate the number of prints needed for each component, making it easy to understand printing positions. Custom supports on upper body and shoulders require removal after printing. PLA plastic can be used for printing, and no supporting material is necessary. Where support is needed, it has been embedded in the model. For more details about assembly, check out pictures and the robot's STL file. Motor pulleys were fixed with A+B glue to printed parts, but short screws are recommended instead, as they can be removed later for angle adjustments. All motors have a 180-degree rotation, and everything is mounted at middle position (90 degrees) by default. Unfortunately, my programming knowledge is limited, but I will try to program Arduino for this robot. The Arduino Mega is recommended due to its sufficient pwm pins to support all servo motors. If you feel capable of programming this robot, please take on the challenge, and I'll give you credit here!
