Bionic Robotic Hand STEM Lab BIO01

Middle School Bionic Hand Biology Lab: 3-page STEM packet on musculoskeletal anatomy, flexor tendon tension, biomimicry, & grip efficiency math.

Explore human body systems, musculoskeletal anatomy, flexor tendon mechanics, biomimicry engineering, and mechanical advantage! The Bionic Robotic Hand Tendon Mechanics STEM Lab (BIO01) challenges middle school student teams to act as biomedical engineers, designing and building an articulated 5-digit prosthetic hand controlled by internal string tendons to grip and lift payloads.

Students explore bones and phalange joints, muscle contraction vs. tendon tension, prosthetic biomimicry, grip friction, and mechanical efficiency math!
