Abstract

A fully floating contact redirecting device for a cleaning robot, wherein a contact unit is floatingly disposed on a surface of a robot body in a forward direction, and at least one sensing unit is respectively disposed on opposite sides of the contact unit in a direction opposite to the forward direction. An angle at which the robot body is retracted and turned to avoid a wall or an obstacle is determined by a position where the contact unit goes into contact with the sensing unit after the contact unit touches the wall or the obstacle, thereby solving the problem of going through multiple turns to move in an obstacle-free direction and improving the cleaning efficiency of the cleaning robot.
