采用神经电生理学方法，用微电极细胞外记录大鼠孤束核单个神经元的活动，观察在正常生理状态及胃运动增强和胃运动抑制的病理状态下，分别针刺&足三里&&内关&&中脘&&气海&对孤束核神经元放电及胃内压的影响。

Aimed at 9-degree of freedom hyper-redundant module robot in intra-vehicular robot system, attention is given to the avoiding joint limits as an optimal mark. Two different iterative algorithms considering fault-tolerance for trajectory planning of redundant robot in Cartesian space are then proposed by using the method of differential locomotion. The first algorithm is for linear-path in which the pose of manipulator can be changed, the second is for circular-path in the plane decided by three noncollinear arbitrary points in the space. Experiments on the specimen robot platform are performed to validate the above algorithms.
