How to make DIY ramp walker physics toys

Built to take measured steps with swinging or rocking legs, ramp walkers are physics toys that use gravity to slowly waddle their way down ramps. Ramp walker toys have been around since the late 1800s, first made from cast iron, then wood, and then mass-produced in plastic during the 1950s and 60s. Today, makers are also 3D-printing them with custom designs and themes. From 3ders.org:

“Just like a windup toy uses potential energy stored in a spring, the walking toy uses potential energy as it descends downhill,” explained Pranav Bhounsule, assistant profess of mechanical engineering… “However, unlike a windup toy that has an intricate mechanism, the walking toy relies on its mass distribution, inertia, and leg geometry to amble downhill.”

In the video above, retired physics teacher Bruce Yeany creates ramp walkers with cardboard, making them both an excellent DIY craft and a physics demonstration.

Watch the video above to learn how to make your own with cardboard, scissors, and your choice of art materials. Hot glue is optional. Yeany also shares wooden ramp walkers from his collection.

While much easier than ones made from wood, [cardboard ramp walkers] are also less durable and may be a bit more temperamental requiring adjustments are cardboard integrity changes. Ramp walking toys have actually been around for quite a while, the first ones were metal elephants produced back in the 1800s. In the 1930s and 40s, the popular material was plastic made that was made into Disney and other popular characters. Recently there has been a surge in wooden ramp walking toys. The wooden toys are very durable but require woodworking tools for making them.
