The serial-parallel robot can be resolved into the serial combination of two parallel robots. Each branch chain of the parallel robot is all a serial branch chain. By utilizing the kinematics equivalency and considering the influences on posture errors of the final moving platform affected by end errors of each branch, the synthetic analytical method based on dynamic and static factors was put forward. The main affection factor was presented and effectiveness verification has been carried out on the conclusion of study by the form of a living example.

Rescue Robots

Cable-driven parallel robots are being developed for rescue operations in large-scale earthquake disasters. This paper proposes an identification method of kinematic parameters for the installation, such as the position of cable fixture by initializing motion on site. This problem is unique to robots in natural fields, such as disaster sites because the environment is not structured. On the basis of identification error analysis and simulation, the optimal number of measurement points and the size of an identification reference frame are obtained.

Motion accuracy is one of the key point for parallel robots. In the paper, error modeling and motion error analysis of a 3-DOF parallel robot 3-PRS has been studied in this paper. First, the 3-PRS parallel robot and its kinematics has been introduced with its kinematics analysis. Based on the reverse kinematics analysis of 3-PRS, the motion error has been modeled. Then, motion error analysis has been performed for 3-PRS. The analysis results show the clear tendency of structural error effects on the motion errors.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.

Learning Test

Performance on a German version of the Rey Auditory-Verbal Learning Test (AVLT) was investigated for 64 juvenile patients who were subdivided in 6 clinical groups. In addition to standard evaluation of AVLT protocols which is usually confined to items recalled correctly, an error analysis was performed. Differentiating between total errors (TE), repetition errors (RE), and misnamings (ME), substantial differences between clinical groups could be demonstrated. It is argued that error analysis of verbal memory and learning enriches the understanding of neuropsychological syndromes, and provides additional information for diagnostic and clinical use. Thus, it is possible to gain a more accurate picture so that patients can be appropriately retrained, and research into the functional causes of memory and learning disorders can be intensified.
