We present an example-based approach to synthesizing physically simulated Rube Goldberg machines in which a series of rigid body elements are sequentially triggered and driven along the causal chain. Given a set of elements, our goal is to automatically instantiate and arrange those elements to meet the user-specified requirements including the start and end positions, and the boundary of movement. To do so, we first sample small-scale machines consisting of only a few elements randomly, and represent the connectivity between every pair of components as a graph structure. Searching over possible paths in this graph solves our problem by finding a path that can be unrolled to satisfy the given requirements, and then assembling components sequentially along the solution path. In order to ensure that the machine works precisely in a physically simulated environment, we finally elaborate the layout of assembled components by a simple greedy algorithm. We demonstrate the usefulness of our approach by displaying a large diversity of Rube Goldberg machines built with only five kinds of elements.

This paper is researched the methods of design instruction which can improve students' creativeness through the subject of creative engineering design as a required subject for the accredited engineering program. After studying the preference and problems of design tasks for the students of engineering college, a new education development plan for design process was suggested, which uses the existing design tasks in which creativeness improvement class was focused through the completion of structures. This was through the completion of structures that 'operating the most simple operation with the most complex mechanical mechanism', which uses Rube-Goldberg, the crystal of mechanical mechanism in the union of multi-disciplinary convergence curriculum.
