矿井救援机器人结构设计
摘要
灾害发生之后为了能够尽快地搜救被困人员,人们开发了各种各样的灾害生命搜索定位设备,搜救机器人就是其中的一种。本文详细介绍了履带式复杂地形机器人平台结构的组成。首先对履带机器人移动平台的总体结构进行设计,进而设计了移动平台的驱动部分结构,同时考虑了机器人移动平台的通用性,设计了回转平台结构和升降机构,以便机器人能够适应不同的环境的工作。本文还对驱动系统中间传动机构进行了设计计算和校核。从机器人的行走条件入手,建立其运动模型,对机器人行走系的运动学与动力学进行分析,对运行及越障过程和抗倾覆能力进行分析研究。通过分析计算本设计能够满足设计要求,为下一步深入研究奠定了基础。
