In the animation of deformable objects, collision detection and response are crucial for the performance. Furthermore, a physically correct cloth simulation requires robust collision avoidance, since any overlapping is visible and often results in expensive correction procedures. Much progress has been achieved in improving the numerical solution, and therefore most animations employ large time...

A simple time delay method for avoiding collisions betweentwo general robot arms is proposed. Links of the robots are approximatedby polyhedra and the danger of collision between two robots is expressedby distance functions defined between the robots. The collision mapscheme, which can describe collisions between two robots effectively, isadopted. The minimum delay time valu...

Collision detection is a fundamental geometric tool for samplingbased motion planners. On the contrary, collision prediction for the scenarios that obstacle’s motion is unknown is still in its infancy. This paper proposes a new approach to predict collision by assuming that obstacles are adversarial. Our new tool advances collision prediction beyond the translational and disc robots; arbitrary ...

This paper focuses on the optimization of initiating dimensions of groove bearing in association with de- sired design of vehicle’s front structure which is made up of low carbon steels in the case of frontal collision. Axial bearing analysis is done numerically using nonlinear finite element code LS-DYNA. In this analysis, changes of two main parameters including measure of energy absorp...

We revisit the computation of probability of collision in the context of automotive collision avoidance (the estimation of a potential collision is also referred to as conflict detection in other contexts). After reviewing existing approaches to the definition and computation of collision probability we argue that the fundamental quantity that is required to answer a question like ”What is the ...

Intersection-collision warning systems use vehicle-to-infrastructure communication to avoid accidents at urban intersections. However, they are costly because additional roadside infrastructure must be installed, and they suffer from problems related to real-time information delivery. In this paper, an intersection-collision warning system based on vehicle-to-vehicle communication is proposed i...

The problem of collision detection of functionally defined objects based on perturbation functions for constant time is considered. The collision detection algorithm of different complexity during a constant time is discussed. Recursive object space subdivision algorithm is proposed. In the perturbation function representation, collision detection becomes trivial due to the inside/outside prope...
