This paradigm has been developed with the purpose of achieving a suitable representation in the modelling, and the design of sensor-fusion.

This characterization represents a new contribution to the development of systematical representations, based on rigorous mathematical formulations that is defined with the purpose of reducing the empiric aspects of the modelling, and design of the sensor-fusion.

The proposed sensor is based on a 1 MPixel CMOS sensor and includes a digital signal processor that directly performs low level image processing algorithms thus eliminating the need of high-bandwidth communication channels between the sensor and the host PC. The design targets at high frame-rates, low power-consumption, and small size of the final sensor.

Advantages of the spherical mirror are its large field of view, good focus over the entire field, simple construction, and low manufacturing cost.

We observed that it is not appropriate to use the mean squared error (MSE) as the only criterion in the evaluation of the de-noising results of mechanical signals. As such, we proposed a combined criterion incorporating both MSE and false identification energy (Efalse) to evaluate the de-noising results. In our simulation studies, the proposed hybrid thresholding approach outperforms both the soft- and hard-thresholding methods in terms of the combined criterion. The proposed approach is then successfully applied to noise reduction and fault feature extraction of bearing signals","PeriodicalId":244890,"journal":{"name":"International Workshop on Robotic Sensors: Robotic and Sensor Environments, 2005.","volume":"177 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113960098","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}

This paper presents a novel technique of dual feedback & feedforward synchronized cross-coupled motion control (DFFSCCC) for two-wheel mobile robot to achieve higher accuracy. previous cross-coupled motion control techniques are based on the consideration of only internal disturbances. The technique presented in this paper is based on the consideration of both internal and external disturbances. Similarly, previous cross-coupled motion control techniques used only feedback signals to correct the errors of the system. DFFSCCC has employed feedback and feedforward signals at the same time to achieve more accurate results. DFFSCCC has been mathematically modeled and simulated by using MATLAB-SIMULINK. The achieved results show that the suggested technique is robust and yield zero transient response and zero steady state errors. Hence, DFFSCCC can yield zero position and orientation errors which can keep the mobile robot on the same trajectory path, either straight or curve, despite of continuous disturbances that may affect either of motors","PeriodicalId":244890,"journal":{"name":"International Workshop on Robotic Sensors: Robotic and Sensor Environments, 2005.","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127128256","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}
