Mechanical Arm (Inspired by Silver from Treasure Planet)

I recently saw the movie "Treasure Island" and was fascinated by the complexity of the mechanical arm that the cyborg, also known as "Silver" has. I decided to recreate it in my own way with a bit more of a realistic metallic look that showcases what it might look like if a prototype of it was made nowadays! It was a fun project that challenged me with the complexity of the arm, and I had to look into how the joints would work so it could look viable!
