RESEARCH: Stanford Pupper - An Inexpensive & Open-source Quadruped Robot
Stanford Pupper is a small quadruped robot that can hop, trot, and run around. We hope that its low cost and simple design will allow robot enthusiasts in K-12 and beyond to get their hands on fun, dynamic robots.
RESEARCH: SpotMicroAI, Low cost and Easily built Quadruped Robot
Key Benefit: Light weight, low cost robot dog based on 3d printed parts. Uses 12x cheaper hobby servos.

PROJECT VISION & GOALS
VISION
This project is perhaps the most academic robotics project with the goal of studying the robot gait and movements based on the program (software code) and actuators/servos (hardware). As such, I chose to go with the Quadruped (4 legged) robot with 4DOF (4 joints per leg). Perhaps the more popular approach is the go with the biped (2 legged) humanoid, but doing so will require much much more effort and time. A simpler approach is to go with the quadruped approach due this design approach having been adopted by many of the living animals over millions of years. I have attached a couple YouTube video that inspired me to move forward with the project
GOALS - 2020
Research and acquire a base robot framework - robot body, servo, controller, sensor
Research and test several gait development platforms - RSO, Cynthiam, ArbotiX/Arduino
Acquire and test many popular gaits for Quadruped 4DOF and 3DOF
Get to know the current projects of many researchers and individual makers
