Virtual Prototype Realization and Simulation for Small-Caliber Deep Well Rescue Robot

In order to improve the backward present rescue technique for small-caliber deep well, a kind of rescue robot is studied, which can hold and grasp the fallen person tightly by using the stretching arm and clasp arm. The virtual prototype is designed to illustrate the rescue course. Considering the stretching arm of the robot bear the main weight during the rescue work, so we make the stress analyses about the connecting rod joint and supporting bracket joint of the mechanism, moreover, the simulation results of stress distribution about the connecting rod and the stretching arm are also finished, figures show that the robot is competent for enduring the weight caused by the fallen person. Therefore, the design method of the rescue robot is feasible.
