Day 13 — Robotics Arm Project
Time spent: 3 hours
Today I shifted my focus from designing new parts to improving and validating the existing CAD model. I reviewed every component of the robotic arm, corrected several design issues, and refined parts to improve their fit and overall manufacturability. I also planned the wire routing for the arm, making sure each joint would have enough slack for its full range of motion while reducing the risk of wires being pinched during operation. To finish the session, I began preparing the arm for simulation by exporting the assembly from Onshape using the onshape-to-robot exporter. During this process, I discovered that my assembly mates and material properties still need to be configured correctly before the robot can be successfully simulated in PyBullet. Next, I’ll fix the assembly mates, assign materials to every part, and begin testing the robotic arm in simulation.
