The Razorback – Part 18: Splitting the Upper Arm Into Two Parts

In this part of the Razorback series, we split the upper arm into two pieces. Earlier on in the series I wanted to keep the robotic arms as simple as possible, and while doing so, I unintentionally hampered the range of motion. The following video follows me as I try to correct this situation. The result is actually better looking in my opinion.

Covered in this video:

  • We do a few tests for the limitations that are already in place. For example, what happens when we spin the blade around?
  • At around six minutes in, we create a visual aid and starter object where we will cut the arm and add the “wrist” pivot.
  • Near the eleven and a half-minute mark, we prepare the existing arm geometry for the cut.
  • Later on, we rearrange the hierarchy a bit so the upper arm now moves as two separate parts.
