A Novel Path Control Algorithm for Networked Underwater Robot

Journal of Robotics, 2018
Under the network environment, the traditional control method of underwater Robot path has the disadvantages of low control accuracy, large error, and inefficiency. This paper proposes a novel path control method for underwater Robots based on the NURBS (

Adaptive Tessellation of NURBS Surfaces. [PDF]

, 2003
NURBS surfaces are widely used in computer graphics, due to their great accuracy of design and reduced amount of data needed for representation. For real-time visualization, tessellation algorithms are needed, as they make use of the actual graphics hardware through the conversion of surfaces to triangle meshes. The existent algorithms for tessellation

Surface Fitting with NURBS - a Gauss Newton with Trust Region Approach : 13th WSEAS International Conference on APPLIED MATHEMATICS Puerto de la Cruz, SPAIN, DEC 15-17, 2008

, 2008
This paper shows a new approach for non-linear least squares fitting with NURBS as curves and surfaces to measured data by the Gauss-Newton method. A Trust Region algorithm is used to reach global convergence as well as variable substitution and simple ...
