Design and analysis of buffer mechanism based on dumbbell type throwing robot

On account of the special properties, throwing robot can be used as a military robot, which is suitable for detection, anti-terrorism, harsh environment detection and other scenarios, and has a good application prospect. In this paper, a buffering pleated mechanism based on dumbbell type throwing robot are proposed. The buffering energy absorption characteristics of pleated structure are compared and simulated by FEM based on Abaqus software. Designed for water and land patrol, the throwing robot contains two symmetrical trailing wheels coupled with the pleated structure to meet the requirement of balance. The results show that the buffer mechanism is compact, economical and possesses a high space utilization rate, reflecting its practical value.
