Robot Arm: Design So Far

This robotic arm was an early personal project aimed at building a fully 3D-printed, six degree-of-freedom manipulator as a learning platform. The arm was designed to reach roughly 60 cm from the base (J0) to the end effector and was powered by DC motors with integrated encoders that I already had access to. Control was handled by an Arduino Mega (ATmega2560), which coordinated motor control and sensor feedback while serving as the main development platform for experimenting with robotic motion.

The mechanical structure was designed entirely around additive manufacturing, with the goal of creating a lightweight but functional prototype that could be iterated quickly. Alongside the mechanical design, I also developed a custom PCB to manage motor drivers, encoder inputs, and system wiring. While ambitious for an early project, the design served primarily as a learning exercise in robotics, electronics integration, and system-level design.
