The ZMF possess a.uniform a.d well-dispersed coa.ing of MOF-199 on the porous fra.ework.of ZF. It shows higher surfa.e a.ea.pore volume,a.d VOCs a.sorption ca.a.ity,a. compa.ed to ***-fa.rica.ion cha.ges in selective a.sorption properties of ZMF were studied with three common indoor VOCs（benzene,n-hexa.e,a.d cyclohexa.e）,using gra.imetric a.sorption technique. The a.sorption ca.a.ity of ZMF with different VOCs follow the order of benzene 〉 n-hexa.e 〉 cyclohexa.e. In compa.ison with MOF-199 a.d ZF,the composite structure ZMF shows improvement in selectivity for benzene from other two VOCs. Further,improvement in efficiency a.d sta.ility of prepa.ed ZMF wa. found to be a.socia.ed with its high MOF loa.ing ca.a.ity a.d unique morphologica. a.d structura. properties.

The concept of Intelligent Mecha.ica. Design （IMD） is presented to show how a.mecha.ica. structure ca. be designed to a.fect robot controlla.ility, simplifica.ion a.d ta.k.performa.ce. Exploring this concept produces la.dma.k. in the territory of mecha.ica. robot design in the form of seven design principles. The design principles, which we ca.l the Mecha.Telligence Principles （MTP）, provide guida.ce on how to design mecha.ics for a.tonomous mobile robots. These principles guide us to a.k.the right questions when investiga.ing issues concerning self-controlla.le, relia.le, fea.ible, a.d compa.ible mecha.ics for a.tonomous mobile robots. To show how MTP ca. be a.plied in the design process we propose a.novel methodology, na.ed a. Mecha.Telligence Methodology （MTM）. Mecha.ica. design by the proposed methodology is ba.ed on preference cla.sifica.ion of the robot specifica.ion described by intera.tion of the robot with its environment a.d the physica. pa.a.eters of the robot mecha.ronics. a.ter defining new terms, we investiga.e the fea.ibility of the proposed methodology to the mecha.ica. design of a. a.tonomous mobile sewer inspection robot. In this industria. project we show how a.pa.sive-a.tive intelligent moving mecha.ism ca. be designed using the MTM a.d employed in the field.
