An algorithm that shapes objects to cause them to roll down ramps

An algorithm that can be used to find the shape of an object to cause it to roll down a ramp following a desired path
A team of physicists and mathematicians at the Institute for Basic Science's Center for Soft and Living Matter, in South Korea, working with a colleague from the University of Geneva, has developed an algorithm that can be used to find the shape of an object to cause it to roll down a ramp following a desired path.
