Quadruped Robot

pinshape

A Simple Design for a Quadruped Robot. The robot is easy to print on a small hobby-grade printer, such as the one depicted printed with a Printrbot Simple Metal. Assembly doesn't require screws or bolts; parts click-fit together (0.3mm of tolerance). #Updated 3.11.16 I made some small changes to the design based on feedback: larger room for electronics and a better fit/lock system for the "belt." A new set of STL files is uploaded. For the electronics, you'll need eight servos (9G), a microcontroller, a servo controller, and power. The model in the picture uses an Arduino Uno (https://www.adafruit.com/product/ ... ), Adafruit 16-Channel 12-bit PWM/Servo Shield (https://www.adafruit.com/product/ ... ), four AA battery holders (https://www.adafruit.com/product/ ... ), and eight MG90S high-speed micro servos with metal gears. There isn't much room in this setup, so I plan to order an Adafruit Feather (https://www.adafruit.com/product/ ...) and an 8-channel Servo FeatherWing (https://www.adafruit.com/product/ ... ). The robot was designed using OnShape, a browser-based parametric CAD software package. You're free to copy or customize the project. The link to the project is: https://cad.onshape.com/document/ ... OnShape is free for up to 10 private projects and unlimited public projects. You can read more about other quadruped bots at my blog, www.burningservos.com.
