摘要

To verify and evaluate the performance of a space robot controller, kinematics and dynamics of the system have to be formed beforehand for computer simulation. The paper is devoted to develop a new kinematic notation for space robots and to come up with an open source of Matlab subroutines for the propose of obtaining the proper dynamics equations of space robots in symbolic forms automatically. For the new kinematic notation, we will present the general form and two special cases. It is then demonstrated through an example the advantages such as flexible assignment of frames on space robots, being able to describe multi-DOF joint and achieve a consistent description for multi-arm space robots. For the second part, we adopt the Lagrangian Formulation for forming the procedures to automatically generate the dynamics equations of space robots in symbolic forms. An example is then provided to demonstrate the effectiveness of closed-loop simulation adopting the obtained symbolic equations.
