Dynamic Walker: Physics Experiment for All Ages!

Experience the wonder of physics and biomechanics with this 3D-printable Passive Dynamic Walker!Perfect for all ages, it showcases principles like the center of mass (COM), pendulum and inverted pendulum motion, and their connection to walking gait and friction. Ideal for classrooms, makerspaces, or hobbyists, this walker relies solely on gravity to “walk” step by step down a slight slope, demonstrating dynamics, stability, and motion studies with minimal materials and setup.Use the included CAD model to experiment with changes in part density or dimensions, and compare theoretical COM predictions to real measurements. I've also written a detailed guide on lab activities and the physics behind its movements, be sure to check it out!OnShape Model: LinkWhat Is a Passive Dynamic Walker?A passive dynamic walker is a mechanical device that replicates natural walking with no external motors. By precisely balancing the center of mass and moment of inertia, it reveals how stability and mov
