Project Azure: A Parallel Kinematic Arm
A modular, scalable 3-DOF robotic arm equipped with a precision gripper and an adaptable component system for external motors and counterweights. https://canva.link/zimx2xk4dunu3mu

I am building a unique, 3-DOF parallel-linkage robotic arm that utilizes a mathematically perfect parallelogram geometry to keep the joints parallel while relocating heavy motor mass to the stationary base. This design solves the lack of practical desktop robotics by providing a highly professional, scalable robotic assistant capable of reliably holding, positioning, and moving objects on a workstation. The two large base gears operate independently to drive distinct axes of rotation across the primary bicep and the parallel support linkage. By coordinating the specific angles of these dual gears, the system can precisely dictate both the vertical height and horizontal reach of the robotic arm. So far, I have successfully modeled the core structure with filament-saving cutouts in the main arms and built out the initial synchronized gripper assembly. My current focus is refining this digital model by setting precise angle limit mates, finalizing the color scheme, and scaling down the bulky base and refining the vertical claws on the gripper sub-assembly. Ultimately, this complete CAD model will serve as the exact blueprint for my summer project, where I will fabricate a physical, 3D-printed prototype of the arm.
