Robotic Arm

Project Overview

Led the complete design, manufacturing, and integration of a multi-degree-of-freedom robotic arm. The project required systems-level thinking across mechanical design, materials selection, manufacturing planning, motor and actuator selection, and control system integration.

Design Phase

• CAD modeling in SolidWorks — full assembly with joints, links, and end effector
• Structural analysis — static and dynamic load analysis at each joint
• Motor and actuator selection — torque requirements based on payload and reach
• Material selection — weight-to-strength optimization for arm segments
• Technical drawings — GD&T per ASME Y14.5 for all manufactured parts

Manufacturing Phase

• Fabricated structural components using manual mill and lathe
• 3D printed non-structural and complex geometry components
• Assembled joint mechanisms with proper fit and tolerance stack management
• Produced and verified parts against engineering drawings

Integration & Control

• System integration — mechanical, electrical, and software subsystems
• Motor driver and controller wiring and configuration
• End-to-end testing — range of motion verification and payload testing
• Documentation — test procedures and system specifications
