- (mathematics) A solid shape that traces a periodic trajectory when rolled down a slope.
- 2023, Sobolev, Y.I.Dong, R.Tlusty, Tet al., “Solid-body trajectoids shaped to roll along desired pathways”, in Nature[1], volume 620, pages 310–315:
- Here, we develop an algorithm to design such bodies—which we call ‘trajectoids’—and then validate these designs experimentally by three-dimensionally printing the computed shapes and tracking their rolling paths, including those that close onto themselves such that the body’s centre of mass moves intermittently uphill.
