The Design and Development of a Portable Assistant Manipulator for High Altitude

针对国内果农持续高空作业、劳动自主性较差的问题开发了整合高度、角度和长度三维空间于一体的小型便携式高空辅助采摘机械手。利用单齿轮双齿条机构实现长度控制,并按弯曲疲劳强度条件进行了参数设计,基于CATIA平台进行了结构设计和运动仿真,通过ANSYS/Workbench软件对关键零部件进行了强度校核,提高了产品可靠性和开发效率。成品试验结果表明,该设备效果良好。

To solve the problems of continued high-altitude labor and lack of autonomy for fruit grower in China, this study presents a small-sized portable assistant manipulator for high altitude with three dimensions of height, angle and length. The length is controlled through single-gear and double-rack and the parameters are designed according to bending fatigue strength.The structure design and dynamic simulation are carried out using CATIA software, and the strength of key parts is checked with ANSYS/Workbench to improve reliability and development efficiency. The testing of finished products indicates that the manipulator has the excellent performance.
