Day 14 — Robotic Arm Project
Time spent: 2.5 hours
Today I worked on creating an animation of my robotic arm to better visualize how all of the joints move together before building the physical prototype. I explored several approaches, including exporting the CAD model for simulation in PyBullet, but ran into issues with the assembly not exporting correctly due to missing joint definitions and material properties. Instead, I used Onshape’s Gear Relation feature to synchronize the movement of multiple joints, allowing me to create a smooth animation driven by a single input. This gave me a simple way to demonstrate the arm’s motion and better understand how the overall mechanism behaves. Next, I’ll continue refining the CAD assembly, prepare the design for 3D printing, and complete the remaining project documentation.
