针对林业领域高空作业劳动强度大、危险系数高等问题,开发一种基于ATmega 128处理器的活立木攀爬机器人。通过机械结构、工作原理、控制器的硬件组成和软件设计四个方面阐述了机器人的实现方法,旨在说明其可实现负重攀爬活立木,且具备较强的负重攀爬能力和稳定的运动特性。经验证,本文设计的活立木攀爬机器人可完成承载设备和攀爬任务的工作。 Aiming at the problem of high labor intensity and high risk coefficient in aerial work in forestry field, a kind of living timber climbing robot based on ATmega 128 processor was developed. Through the mechanical structure, working principle, the controller hardware composition and the software design four aspects of the realization of the robot, aims to demonstrate that it can achieve the weight of climbing live wood, and have a strong load climbing ability and stable movement characteristic. Proved, this article designed living wood climbing robot to complete the task of carrying equipment and climbing tasks.
