In this robot, nonlinear effects due to centrifugal, Coriolis, and gravity forces are more important than friction forces. The control law of the adaptive scheme consists in a PD regulator and feedforward compensation of full dynamics. The feedforward terms are adjusted by an adaptation law so that the steady-state position errors are zero. The regulator gain matrix can be fixed or time-varying; in the latter case, the adaptive scheme becomes similar to the computed torque scheme. However, with the adaptive controller, joint accelerations measurement is not required and no inversion of the estimated mass matrix is involved. The tracking performances of the controller applied to a 4 d.o.f. SCARA robot are illustrated by a digital simulation.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125034540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

K-NET can support all development stages including general design, detailed design, programming, and testing.

Range data obtained through active triangulation have comparatively high accuracy. However, range cannot be determined uniquely from a single-input image. On the other hand, range data obtained by the method using astigmatism are determined uniquely, but one cannot expect a high degree of accuracy. To improve the performance of the sensor, a novel method that fuses the range data obtained by these methods is proposed.
