A flexible-rigid multibody analysis was performed to examine the dynamic response of a heavy handling robot system under a worst motion scenario. A rigid body dynamics analysis was solved and compared with flexible-rigid multibody analysis. The modal analysis and test were also carried out to establish the accuracy and the validation of the finite element model used in this paper. For the flexible-rigid multibody simulation, stresses in several major bodies were interested, so that those parts are flexible and other parts are modeled as rigid body in order to reduce computer resources.

The purpose of this study was to research the effects of exercise programs on genu varum persons` distance of between two legs. Method 40 persons who had genu varum were participated in this research. Randomly, among 30 were allocated in experimental group and others were allocated in control group. Stretching exercises, bend exercises and joint mobilization were applied to the experimental group for 6 weeks. For the statistical analysis, we used the independent t-test and the paired t-test. Result Stretching exercises, bend exercises and joint mobilization had statistically effects on distance of knees with gathering legs, distance of knees, distance of malleoluses, differences of distance from between malleoluses to between knees by GPS. Stretching exercises, bend exercises and joint mobilization had statistically effects on distance of knees, distance of malleoluses by ruler. Conclusion Therefore, this study showed that stretching exercises, bend exercises and joint mobilization influenced on the change of genu varum.
