Update v0.6

I sat down to correct some of the things I considered be weaknessess in the design. Mainly the fasteners. 
I wanted to keep this version of the Quadruped budget friendly. 
The more robust big brother Quadruped v1.0 is more expensive with bearings and more robust components.

No code or electronics were changed. The only change to v0.6 was the mechanical components.

What's the difference between the versions?

Quadruped I has less parts.
It has 10 servos where only the front hips can pivot, making its movement more restricted than it's big brother Quadruped II.

It has less components and more simple electronics. All of the parts and joints is 3D-printed.

Quadruped II has bearings and 12 servos. 
It also has a custom power distribution board to make the assembly more easy.
It has ROS 1 Noetic implementation aswell which enables another level of flexibility. 

Quadruped I is a great starter DIY project.
Quadruped II is more advanced but also more expensive.
