Robotic Grip

Overview

Many robotic hands are expensive and too complicated for most people to build or understand. For my project, I designed a simple solution called Robotic Grip that costs under $50 and uses 3D printed parts as well as small motors and basic electronics. I modeled the hand in Onshape and printed the parts on an Ender 3 V3 SE printer. It easy to assemble the fingers and mount the motors to the palm. I programmed using an Arduino and powered the hand with 4 AA batteries. The hand was able to hold many everyday objects(like water bottles), showing that a low cost design can still be strong and useful. To keep the cost low, I used affordable SG90 motors, lightweight parts and simple electronics. This project is important because it shows that affordable robotics can still work well and could be useful for learning, research, medicine, construction and more.
