Rube Goldberg Machine A Rube Goldberg machine, named after American cartoonist Rube Goldberg, is a machine intentionally designed to perform a simple task in an indirect and overly complicated way. Usually, these machines consist of a series of simple unrelated devices; the action of each triggers the initiation of the next, eventually resulting in achieving a stated goal. 1Due to the special situation because of the epidemic around the world this year, we have to have this program online, therefore, the machine is not in real world but is a simulation by blender 3D 2.8. And to track and analyze the physics underlying individual step. The main purpose of my Rube Goldberg machine is to build up a device with several steps to push a switch in the end. There are also constraints that the steps must contains 7 part in physics which are elastic collision, inelastic collision, conservation of momentum, conservation of energy, projectile, circular motion and torque.
