GoodBoy is a 3D printed Arduino Quadruped Robot

GoodBoy is a small quadruped robot using 3D printed parts. Inspired by the robots dog of Boston Dynamics, designed the robot to be compact, simple, and inexpensive to build.

The author explain in details the process of having an idea and transform it to a full prototype going through different iteration.

The first design had several issue as the motor’s force was not enough to sustain the structure( Sg90 or similar) . The new design balance the weight on a wider area at different angle to increase the balance. Good job ! 🙂

 

A clever Builds Process

This project uses an Arduino Uno as the brain but another micro-controller like ESP8266 , RaspberryPI or Micro:Bit can be used.

The full BOW list is the following:

  • Arduino Uno (genuine or clone)
  • Adafruit Powerboost 1000C
  • 18650 Li-Ion Battery
  • HC-SR04 Sensor x 2
  • 9g Servo x 8 (Towerpro SG90 or similar)
  • LDR x 1

We want to  mention that the author included several clever ideas to simplify the build and create the peculiar robot’s silhouette :

  • Embedded electrical cables during 3D printing, pausing the printer and add the cable, then resuming the 3d printer.
  • Advanced supports for complex overhangs using Meshmixer
  • Friction fitted parts, in order to reduce glued parts and nuts
  • Integrated hex nuts for bolts in the body of the robot during printing.
