anatomy + robotics + prothetic limb.
Studies of anatomy, robotics, and a thesis in prothetic limbs resulted in the interest of recreating of the hand and it's mechanical movement. Through anatomical studies from different textbooks and visits to cadaver labs, drawings were made dissecting the flexers and extenders, and mockups were made of articulating hand movement through 3D printing. Programming motors and sensors with Arduino allowed iterations of different robotic movements to show a specific output. The final model uses three buttons to control the motors, which are each hooked up to certain fingers.

The final model uses fishing line to mimic extenders and flexors. Servo motors control the "contraction" movements of the fingers. Each motor is connected to a button that the user can press at their own interest, experiencing the resulting movement.
The left hand video shows an early prototype where a proximity sensor was used to stimulate the "contraction" movement created by the motors.
