For a parallel configuration of a robot manipulator, the solution of Forward Kinematics (FK) is tough compared to Inverse Kinematics (IK). This paper presents the model-based motion planning of a delta parallel robot in Simulink’s SimScape environment. A model was developed and simulated for motion study. The developed model has been simulated to solve the FK of the parallel manipulator and to check its efficacy. First, a helix curve has been planned within the reachable workspace. Then IK was solved to extract angular positions of the biceps. Obtained angular positions then fed to SimScape model to run a simulation. The path taken by the end effector of the system calculated by simulation is in good approximation to the planned helix path. Further, visual simulation and motion analysis of delta parallel robot can be performed by Model-based simulation and solves mechanical design as well control system design problems. Experimental study also shows that the circular path designed for experiment is well followed in real time simulation.

The present investigation in to find out the Adjustment of Secondary School Students in Relation to their gender boys and girls. The sample consisted of 120 secondary school students out of which 60 where boys and 60 where girls. For this purpose of investigation “Adjustment Inventory” by Dr.R.S.Patel was used. The obtained data were analyzed through ‘t’ test to know the mean difference between secondary school students in relation to their gender. The result shows that there is no significant difference in Home, School and Emotional adjustment of boys and girls secondary school student. But there is significant difference in Social adjustment of boys & girls secondary school students at 0.05 level. It means boys are Social adjustment better than girls
