Here's my first test of three consecutive joints in my bionic hand, using FDM printing and arduino, designed in Fusion 360.

By harnessing the power of 3D printing, servo motors, and Arduino programming, you’ll create a robotic arm that responds to your commands through a sophisticated software interface, allowing for ...

Once the team made MuMuTAs work, they used five of them to actuate multi-jointed fingers in a robotic hand. Rock-paper-scissors The hand, suspended in a liquid medium, was 3D-printed out of plastic.
