Manipulator classification by means of a kinematics description language

This paper presents a universal test data generator for the systematic evaluation of inverse kinematics systems. A Denavit-Hartenberg parameter based kinematics description language LDL has been developed; it is used as input language for the generator. LDL allows the expression of kinematic and geometric constraints, which have to be satisfied by the resulting generated kinematics. Moreover, it is possible to generate certain well-known classes of manipulators. Combining the basic features and different kinds of constraints, a LDL program can be used to define and to generate classes of manipulators.<
