The effection of the different posture in sky on the jump height;

A new definition for orientation space was given based on parameters of orientation,a kind of evaluation indicator about orientation capabilities was given at the same time.

New joints and redundant active UPS(universal prismatic spherical) link were used to enlarge the orientation space of a 3PRS(prismatic revolve spherical) parallel mechanism.

This paper presents a gesture space modeling method in robot motion planning.

This paper presents an approach into building the gesture space for robot motion planning so as to the application for the motion planning of the mechanic arms in the complicated situation.

To measure and control object space attitude accurately in the fields of robot control,aircraft control,complex parts assemble and others have been stadied in this paper.

In order to explore the theoretical foundation of the manipulator,the kinematics performance and the attitude distribution properties in the orientation workspace are investigated.

Then the evaluation indicators of bath the error direction and error absolute according to the Jaclbe matrix are defined,and the distribution graphs of which in orientation workspace are drawn.

Using three non-collinear reference points and a charge coupled device(CCD)camera to get the 3D information of a body,the alignment attitude of a main propulsion engine is described with Euler angles.
