Variable-rate tree spraying is one of the most important technique of precision agriculture. This paper presented an interactive virtual tree spraying method based on particle system, which gain fine control flexible through parameters such as the emitter position and pitch angle, atomizing particle, atomizing anger and spray penetration depth. We proposed a 2-hierarchy collision detection algorithm...
Teams of robots for search and rescue in dangerous building environments are emerging as a potential approach to reducing risk to rescuers and improving rescue rate. However, one aspect of the use of such teams that is often overlooked is the initial entry of the robots into the building. If many robots enter the building from the same entrance, it will often be the case that the robots interfere...
