Attending to generalization capability, Laezza and Karayiannidis [142] formulated a generalizable shape control problem for materials with elastoplastic properties using the rope curvature state representation. However, the approach was simplistic as it restricted the motion of the robot gripper along a st...

in lat/lng degrees. If the ground distance (excluding altitude) between two adjacent path points is larger than this value, the line segment will be interpolated in order to approximate the curvature of the sphere surface. Lower values yield more perfectly curved lines, at the cost of performan...

A lane-detection system is an important component of many intelligent transportation systems. We present a robust lane-detection-and-tracking algorithm to deal with challenging scenarios such as a lane curvature, worn lane markings, lane changes, and emerging, ending, merging, and splitting lanes. ...
RADIUS OF CURVATURE: curvature of the surface at the origin. This is equal to the inverse of the parameter c described in the definition of Sconic. CONIC CONSTANT: The k constant. CUSTOM: Check this option to include the custom term in the surface equation ...
of the line length, causing the curve to approximate a semi-circle. For self-referencing links (sourceequal totarget) the curve is represented as a loop around the node, with length proportional to the curvature value. Lines are curved clockwise for positive values, and counter-clockwise for ...

(e.g., stop signs, yield signs), etc., for example, in a form of an object. The lane configuration includes information describing a lane or lanes, such as, for example, a shape of the lane (e.g., straight or curvature), a width of the lane, how many lanes in a road, one-...
