Optimal Design for Clasp Arm of Small-Caliber Deep Well Rescue Robot

Abstract

In view of the backward present rescue technique for small-caliber deep well, a kind of multifunctional rescue robot is designed, which is composed of a manipulator, a rescue mechanism, an anchorage mechanism, and a set of oxygen supply equipment. Owing to the different postures of the fallen person, the clasp arm of rescue mechanism needs to adjust itself to obtain an ideal rescue orientation in the narrow deep well. Furthermore, the clasp arm bears much more weight when it clasp and fix the fallen person. So, the optimal design about the clasp arm is studied. Meanwhile, based on SolidWorks software, the stress analyses for the designed clasp arm with loads have been finished. Results show that the performance of the optimal designed clasp arm is perfect, which make sure that the rescue robot is capable of carrying out complicated rescue.
