Abstract: A generalized approach and methodology for addressing surface traversal and coverage of a 3 Dimensional (3-D) object receives a 3-D wireframe or similar Cartesian based representation, converts the 3-D representation to a u,v system or mapping. Often employed for texture mapping, u.v grid systems define a two dimensional form of an object, often referred to as “unfolding” of an object. Configurations herein define a u.v grid system directly on the 3-D object for computing a coverage path, typically an aggregation of raster passes to traverse an entire 3-D surface. From a robotic manipulator, a 3D freeform surface, and task constraints, the approach determines whether there exists a feasible continuous motion plan to cover the surface, and if so, produces a uniform coverage path that best satisfies task constraints resulting from the physical object and robot kinematics.
