DIY Robotic Hand - Arduino & DIY Flex-sensor controlled

thingiverse

I've been fascinated with the idea of having a bionic appendage since I was a kid, after watching The Six Million Dollar Man starring Steve Austin. With some extra time on my hands during this pandemic, I decided it's time to bring that dream to life. I got inspired by a video featuring an Arduino-controlled hand made from wooden finger segments. However, tweaking designs in wood is much more challenging than working with computer-aided design software like Fusion360. So, I came up with the idea of creating a 'Carpal Segment' - a basic building block that I could use as a starting point. From there, I started looking around my house to see what materials I could repurpose to create a functional prototype hand. Below, you'll find STL and Fusion360 files for my design. My bionic hand was actually inspired by Homer Simpson's four-fingered hand - it's a lot easier on the hands if you're honest! Each of my fingers is identical in length since they're made from identical segments. These 3D printed Carpal segments can be customized during printing to any length or thickness you prefer.
