本文设计的压力容器检测爬壁机器人采用履带式移动机构，双履带构成爬壁机器人的基本框架；采用永磁吸附方式，将永磁片贴在履带的外表面，可提供足够大的吸附力，结构简单；采用前轮驱动，两个驱动轮分别由电机驱动，当两电动机转速一致时，机器人沿直线行走，当两电动机差速时，可实现爬壁机器人整体转弯。

Magnet, which can offer adsorbability enough to keep the robot working on the vertical walls, is kept close to the outside surface of the pedrails. Front-wheel driving is adopted as the driving system and the two front-wheel are drived by two elctromotors, respectively. When the two motors are running with the same direction, the robot walks straightly. When the two motors are running with the contrary velocity, the robot can swerve.
