6-DOF Kinematic Linkage Assembly
6-DOF Kinematic Linkage Assembly
Project Overview
Project Overview
This project was a self-directed exploration into multi-axis kinematic design and precision assembly. I designed a motor-free, six-degree-of-freedom (6-DOF) mechanical arm in SolidWorks to study how complex motion can be achieved through coordinated joint constraints. The project focused on material optimization and maintaining high-precision tolerances within a multi-component assembly.

Technical Specifications
Software: SolidWorks (CSWA Certified workflow).
Degrees of Freedom: 6 (Full spatial orientation and positioning).
Materials: Aluminum, Cedar, Brass, and Steel.
Precision: Achieved a ± 0.01 mm tolerance across all primary joint connections.
1. 6-DOF Kinematics
Unlike basic 3-joint arms, this design utilizes six degrees of freedom, enabling independent control of both end-effector position and orientation throughout its reachable workspace. Six-axis kinematic architectures represent the industry standard for articulated robotic systems used in industrial automation and high-fidelity themed entertainment applications, where full pose control and expressive motion are required.
2. High-Precision Assembly
To ensure smooth motion without mechanical slop, I utilized top-down assembly modeling to maintain a ± 0.01 mm tolerance. By using advanced mates and limit constraints, I simulated the exact physical range of motion for each joint before moving toward potential prototyping.

Participating in the NASA L'SPACE Academy underscored the necessity of bridging the gap between scientific research and mechanical execution. Successfully integrating the Liulin-MO and TEGA required constant communication with other subsystem leads to ensure that every millimeter of the rover was optimized for both scientific yield and structural integrity.

Project Overview
Project Overview
This project focused on the CAD development and cross-functional integration of mission-critical scientific payloads for a Martian rover concept, completed as a primary deliverable for the NASA L’SPACE Mission Concept Academy (MCA). Working within a multidisciplinary engineering team, I was responsible for the structural modeling and subsystem integration of the Liulin-MO (Radiation Spectrometer) and the TEGA (Thermal and Evolved Gas Analyzer). The central challenge involved translating complex scientific research into high-fidelity 3D models that met strict NASA-defined mass, volume, and power constraints while ensuring seamless physical compatibility with the rover chassis.
