Robotic Hand

thingiverse

This hand is crafted to function in a manner similar to a human hand. By weaving rubber bands through pre-built cavities and holes, users can mimic the recoil effect when a fist is closed. A fishing line or string threaded through the bottom of the hand and fingers serves as tendons, enabling the hand to open and close at will. When relaxed, the strings allow the hand to return to its original state due to the rubber bands pulling in the opposite direction. To further enhance functionality, rods can be inserted into the knuckles, allowing for a more realistic snapping motion. Alternatively, students can design custom clips and rods using a 3D design engine like Inventor, adding an educational component to the project. The hand's design can also be extended by attaching a wrist portion to a broomstick or similar handle, increasing reach and versatility. This product would make an excellent teaching aid for biology classes, allowing students to explore the dynamics of human hands in action.
