Day 12 — Robotics Arm Project

Time spent: 2 hours

Today I finished troubleshooting the remaining gear meshing issues and completed the full CAD assembly of the robotic arm. After correcting both the gear center distance and tooth alignment, the gears meshed consistently throughout their full range of motion. With those issues resolved, the entire assembly is now functional. The base, shoulder, elbow, wrist, and gripper all move as intended, and the gear-driven parallelogram gripper operates correctly. Next, I’ll perform a final review of every part by checking dimensions against the actual hardware specifications, make any final adjustments if needed, and finish the bill of materials before preparing the design for manufacturing.
