Robot ha.ds ha.e been developing during the la.t few deca.es. There a.e ma.y mecha.ica. structures a.d a.a.yti?ca. methods for di erent ha.ds. But ma.y tough problems still limit robot ha.ds to a.ply in homelike environment. The a.ility of gra.ping objects covering a.la.ge ra.ge of sizes a.d va.ious sha.es is funda.enta. for a.home service robot to serve people better. In this pa.er, a.new gra.ping mode ba.ed on a.novel sucked?type undera.tua.ed(STu) ha.d is proposed. By combining the flexibility of soft ma.eria. a.d the e ect of suction cups, the STu ha.d ca. gra.p objects with a.wide ra.ge of sizes, sha.es a.d ma.eria.s. Moreover, the new gra.ping mode is suita.le for some situa.ions where the force closure is fa.lure. In this pa.er, we deduce the e ective ra.ge of sizes of objects which our ha.d using the new gra.ping mode ca. gra.p. Tha.ks to the new gra.ping mode, the ra.io of gra.ping size between the biggest object a.d the sma.lest is beyond 40, which ma.es it possible for our robot ha.d to gra.p diverse objects in our da.ly life. For exa.ple, the STu ha.d ca. gra.p a.soccer(220 mm dia.eter, 420 g) a.d a.founta.n pen(9 mm dia.eter, 9 g). Wha.’s more, we use the rigid body equilibrium conditions to a.a.ysis the force condition. Experiment eva.ua.es the high loa. ca.a.ity, sta.ility of the new gra.ping mode a.d displa.s the versa.ility of the STu ha.d. The STu ha.d ha. a.wide ra.ge of a.plica.ions especia.ly in unstructured environment.

针对传统能量分析和经济分析方法无法合理评价生态经济系统内不同种类的能量或物质真实贡献的局限性,引入生态经济学的能值分析方法,以能值为量纲核算系统的能量流、物质流及货币流,建立能值指标体系,量化、评价系统发展所处的阶段和程度,为区域水资源生态经济系统可持续发展评价提供新的手段和方法.郑州市实例应用显示,郑州市水资源生态经济系统能值可持续指标为0.82,处于消费型阶段,水资源人口承载力为83万人,远远低于实际人口数,水资源压力很大,郑州市水资源生态经济系统尚未进入可持续发展阶段.
