Abstract: An approach to designing a structural combination of multiple materials includes determining, using a physical simulator, simulated measurement data for a first plurality of simulation designs. Each simulation design characterizes a structural combination of a plurality of materials. The simulated measurement data for each simulation design provides a simulation of physical qualities of the design. A subset of the simulation designs is selected based on the simulated measurement data for said simulation designs to yield a set of fabrications designs. This set of fabrication designs is provided for fabrication of a set respective physical samples. A set of physical measurements is received for the set of physical samples. Each physical measurement for a physical sample providing measurements a plurality of physical qualities of the sample.

Abstract: A sweeping mechanism comprises an air duct suction opening (12) formed in the bottom (11) of a shell (1) and at least two sweeping brushes (15) which are independently arranged on the bottom (11) of the shell (1) and are separated from the air duct suction opening (12), and each of the at least two sweeping brushes (15) is driven to move back and forth integrally close to and far away from the air duct suction opening (12). The invention further provides a sweeping robot. The sweeping mechanism and the sweeping robot can effectively solve the problems of dust suction blockage and the like caused by winding due to the fact that the rolling main brush (108) is arranged in the air suction opening (107), and the dust suction efficiency and effect are effectively improved.
