Spot Micro, Part 1

Robot Dog, Part 1.
In this video we will start building a companion for Fred, and who better than a Robot dog.
The first part will be one of the left legs.
This dog looks similar to the Boston Dynamic four legged robot named spot.
This version was created by KDY0523 and named Spotmicro after the Boston Dynamics robot.

Already there have been other creators out there modifying the design to change or add features, so you know I will be looking at those as well.
In the original design, an ArduinoMega 2560 was used to run Spotmicro, however there are mods to allow the use of a Raspberry Pi, so this looks like the way I will be going :-)

This robot uses standard sized servos with most of the body being 3D Printed.
Each leg has 3 servos, for a total of 12 servos.
