Recently, va.ious control methods represented by proportiona.-integra.-deriva.ive （PID） control a.e used for robotic control. To cope with the requirements for high response a.d precision, a.va.ced feedforwa.d controllers such a. gra.ity compensa.or, Coriolis/centrifuga. force compensa.or a.d friction compensa.ors ha.e been built in the controller. Genera.ly, it ca.ses hea.y computa.iona. loa. when ca.cula.ing the compensa.ing va.ue within a.short sa.pling period. In this pa.er, integra.ed recurrent neura. networks a.e a.plied a. a.feedforwa.d controller for PUMa.60 ma.ipula.or. The feedforwa.d controller works instea. of gra.ity a.d Coriolis/centrifuga. force compensa.ors. In the lea.ning process of the neura. network by using ba.k propa.a.ion a.gorithm, the lea.ning coefficient a.d ga.n of sigmoid function a.e tuned intuitively a.d empirica.ly a.cording to tea.hing signa.s. The tuning is complica.ed beca.se it is being conducted by tria. a.d error. Especia.ly, when the sca.e of tea.hing signa. is la.ge, the problem becomes crucia.. To cope with the problem which concerns the lea.ning performa.ce, a.simple a.d a.a.tive lea.ning technique for la.ge sca.e tea.hing signa.s is proposed. The lea.ning techniques a.d control effectiveness a.e eva.ua.ed through simula.ions using the dyna.ic model of PUMa.60 ma.ipula.or.

Ba.ed on the direct numerica. simula.ion （DNS）, the developing pla.a. jets under different initia. conditions, e.g., the con- ditions of the exit Reynolds number a.d the exit mea. velocity profile, a.e investiga.ed. We ma.nly focus on the cha.a.teristics of the inva.ia.ts of the velocity gra.ient tensor, which provides insights into the evolution of the dyna.ics a.d the geometry of the pla.a. jets a.ong with the flow tra.sition. The results show tha. the initia. flow nea. the jet exit is strongly predomina.ed by the dissipa.ion over the enstrophy, the flow tra.sition is a.compa.ied by a.severe rota.ion a.d stra.ning of the flow elements, where the vortex structure evolves fa.ter tha. the fluid element deforma.ion, in the fully-developed sta.e, the irrota.iona. dissipa.ion is domina.t a.d the most proba.le geometry of the fluid elements should rema.n between the bia.ia. stretching a.d the a.isymmetric stretching. In a.dition, with a.sma.l exit Re a.d a.pa.a.olic profile for the exit mea. strea.wise velocity, the deca. of the mea. flow field a.d the ma.nitude of the turbulent va.ia.les will be strengthened in the process of the flow tra.sition, however, a.la.ge exit Re will promote the flow tra.sition to the fully-developed sta.e. The cross-impa.t between the exit Re a.d the exit mea. velocity profile is a.so observed in the present study.

In this pa.er, a.vibra.ion motion control is proposed a.d implemented on a.foa.ed polystyrene ma.hining robot to suppress the genera.ion of undesira.le cusp ma.ks, a.d the ba.ic performa.ce of the controller is verified through ma.hining experiments of foa.ed polystyrene. Then, a.3 dimensiona. （3D） printer-like da.a.interfa.e is proposed for the ma.hining robot. The 3D da.a.inter- fa.e ena.les to control the ma.hining robot directly using stereolithogra.hy （STL） da.a.without conducting a.y computer-a.ded ma.- ufa.turing （Ca.） process. This is done by developing a.robotic preprocessor tha. helps to remove the need for the conventiona. Ca. process by directly converting the STL da.a.into cutter loca.ion source da.a.ca.led cutter loca.ion （CL） or cutter loca.ion source （CLS） da.a. The STL is a.file forma. proposed by 3D systems, a.d recently is supported by ma.y computer a.ded design （Ca.）/Ca. soft- wa.es. The STL is widely used for ra.id prototyping with a.3D printer which is a.typica. a.ditive ma.ufa.turing system. The STL dea.s with a.tria.gula. representa.ion of a.curved surfa.e geometry. The developed 3D printer-like da.a.interfa.e a.lows to directly control the ma.hining robot through a.zigza. pa.h, recta.gula. spira. pa.h a.d circula. spira. pa.h genera.ed a.cording to the informa.ion included in STL da.a. The effectiveness a.d usefulness of the developed system a.e demonstra.ed through a.tua. ma.hining experiments.
