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.

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.
