The solutions were obtained in 6 seconds and 2 seconds respectively. Hence it is possible to obtain faster solutions in real time by dynamically tuning the GA parameters based on required function value or number of iterations and also using a faster computer for running the algorithm. It is however not clear how the function value varies with different shapes and parameter values. In future we hope to study how to adjust the GA parameters dynamically to obtain the fastest solutions in real time. a Figure 9. a-b Finger points for the same object for different functional values b 7. Conclusion The main contributions of this research are an effective vision based method to compute the optimal grasp points for a 2D prismatic object using GA has been proposed. The simulation and experimental results prove that it is possible to apply the algorithm in practical cases to find the optimal grasp points. In future we hope to integrate the method in a multifinger robotic hand to grasp different types of deforming objects autonomously. 8. References Bicchi A. Kumar V. 2000 .
