Although at first sight the desired goal （control objective） of a control system seems to be a trivial and obvious matter, for effectiveness of some high level robotic tasks, unusual exotic control objectives may be required. This paper presents a review of some exotic control objectives useful in robotics, such as velocity field control objective and range control objective. The paper also proposes a novel confinement control objective. The usefulness of these exotic control objectives may appear in safe robot-human interaction and self-protection of robots against collisions.展开更多

In practice, however, the lack of coordination measures necessary between rural tourism and new rural, leading to interoperability between the two thrust did not really been achieved. On the basis of analyzing current interaction of Liangshan rural tourism development and new rural construction, it focus more on discussing the strategy of developing rural tourism in Southwest National Area and the construction of new socialist countryside.展开更多
