Obstacle prevention structure of intelligent robot

The invention discloses an obstacle prevention structure of an intelligent robot. The obstacle prevention structure comprises a rotatable annular support, wherein the rotatable annular support is arranged on the intelligent robot, at least detection devices are arranged on the annular support and are used for respectively checking whether obstacles exist in a part in front of a left side, a rightfront part and a part in front of a right side of the robot or not, distances between the obstacles and the robot and an obstacle moving direction, the arc length of the annular support is at least larger than maximum width of the intelligent robot, the three detection devices are uniformly arranged and are respectively arranged at two sides and a middle position of the annular support, the detection devices are used for sending detection results to a control device, the control device is used for judging whether the obstacles are in a travelling line of the robot or not according to a presetsteering rule and further
