Will be made open-source soon so that others may build for themselves.

Motivated by the high-end robotic arms at the Carnegie Mellon Robotics Institute, I set out to create my own, aiming for a budget-friendly version under $50. While I had a full-time research project during the day, my evenings were dedicated to projects like this one.

My process began with observing the lab's robots and translating ideas into CAD files. I printed a few pieces and gathered hardware for the initial assembly.

The first prototype showed promise but had issues like binding joints and weak points in the 3D print. I decided to order motors, drivers, and other electronics and design the arm around these components

The current design features an Arduino Mega, two L298N motor drivers, two stepper motors, and a 2 axis joystick. I plan to expand the platform to accommodate more degrees of freedom, an array of end effectors, and part interchangeability.

For nearly two months, my days were a cycle of designing changes, printing, assembly, and testing. Each day, I eagerly awaited the completion of a new print.

By the summer's end, I had a functioning robotic arm that cost $57.83. While it's a good starting point, there's room for improvement, cut costs, and have a functional end-effector.
