FlexiVertebra – Parametric Vertebrate Robots

🔧 FlexiVertebra is a fully parametric, bio-inspired articulated robot generator built in OpenSCAD. It allows you to customize and 3D print a modular vertebrate structure composed of:HeadArticulated spine segmentsArticulated Tail segmentsFlexible joints (living flexures)Optional limbs Optional tendon routing channelsThe model is designed around a vertebrate-inspired architecture, combining rigid “bones” with compliant flexure joints to create smooth bending motion using a monolithic printed structure. You can generate:A quadruped lizardA snake (disable limbs)Custom body proportionsTapered tailsAdjustable stiffness via joint thickness (Joint thickness: 1.5 mm (very flexible), 2 mm (Optimal), 3 mm (Stiff), >3mm (stiffer) for robots overall length <30 cm)Add a tendon to the robot and an actuator to the head and control the robot via tendon-driven mechanismAdjustable limb angles (Use splay degree to change limb angles)The entire robot is controlled via parametric sliders inside the OpenSCA
