Comparative study of design and analysis of gripper systems for bore well rescue operation

摘要

Rescuing the trapped child from the bore well is always a challenging task for the rescue operation team. In recent years, rescue robots are used to save the child in short duration. In this work, we designed and developed three types of robotic arms, rectangular, square and cylindrical based mechanical gripper system to rescue the child from the bore well safely. Structural and performance analysis were carried out to check the effectiveness of the robotic arms. It was observed that rectangular and square based robotic arm have high displacement during gripping operation. A high displacement of the arm may lead to cause injuries to the child. We then explored cylindrical robotic arm based gripper system for improving the effectiveness of the robotic arm. Our experimental results show that cylindrical robotic arm outperforms the rectangular and square robotic arm. The robotic arms were practically tested in real rescue operations.
