Robot for highway guardrail plate detection and control method

The invention provides a robot for highway guardrail plate detection and a control method, and the method comprises the steps: collecting an included angle theta'between a body and a lane line, a maximum distance d between the body and a guardrail plate, and a direction angle alpha of the maximum distance d, and calculating a corrected vertical distance D 'between the body and the guardrail plate; and then a control signal uk is calculated according to the preset distance D between the body and the guardrail plate, and finally the tracking track of the robot is corrected, so that the robot can effectively keep a constant distance from the guardrail plate. Through the robot provided by the invention, the sampling parameters of the highway guardrail plate can be rapidly, stably and uninterruptedly obtained, an existing manual detection method is replaced, and the problems that the existing detection efficiency is low, the number of sampling points is small, and mistaken sampling and missing sampling are likely
