Study on the Safety of Wall Robot Based on Redundant Control

The theory of redundant control was applied firstly in the vacuum adsorption system of the wall cleaning robot, and the redundant control system of double vacuum bumps was put forward. It was proved theoretically that in the redundant system, the mean time between failures (MTFB) of the wall robot was prolonged twice as much at least and that the scheme is valid. The conclusion can be drawn that in the course of the two vacuum bumps exchanging the status, the redundant control system is fast, stable, practical and adjustable.
