In the crawling and walking process of the bionic robot, the rotating arm 102 is controlled to rotate by the first motor 107, the first swing arm 103, the second swing arm 104, the third swing arm 105 and the fourth swing arm 106 are respectively controlled to swing by the second motor 108, the third motor 109, the fourth motor 110 and the fifth motor 111, the single-step cleaning area and the single-step crawling distance of the bionic robot are increased, and the obstacle crossing capability of the bionic robot is improved. The single-step crawling distance specifically refers to an offset value of an origin of a reference coordinate system of the bionic robot after the left upper crawling foot, the left lower crawling foot, the right upper crawling foot and the right lower crawling foot move once respectively.

In the embodiment, the bionic robot further comprises a cleaning system, the cleaning system comprises a cleaning water tank 1, a trunk water tank 13, a cleaning water pump 11 and a high-pressure spray head 12, the cleaning water tank 1 is placed at a high position of a building and is connected with the trunk water tank 13 through a cleaning liquid pipeline, the cleaning water pump 11 is placed in the trunk water tank 13 and is connected with the trunk water tank 13, and the cleaning water pump 11 is installed in the trunk 3 and moves along with the trunk 3; the high-pressure spray head 12 is connected with the cleaning water pump 11 and is used for spraying cleaning liquid. A small amount of cleaning liquid is stored in the trunk water tank 13, the cleaning water pump 11 pumps water from the trunk water tank 13, and when the liquid level of the cleaning liquid in the trunk water tank 13 is lower than a set value, the trunk water tank 13 is filled with water through the cleaning water tank 1.

The cleaning water tank 1 is placed at a high position of a building, so that the load of the bionic robot is reduced, and the safety of the bionic robot during operation is improved. In order to further reduce the load of the bionic robot, a power supply system for supplying power to each motor and a motor control system for controlling the motion of each motor are also placed at the high position of the building; the power supply system is connected with the bionic robot through a cable assembly and supplies power to all assemblies of the bionic robot; the motor control system is connected with a control unit 7 on the bionic robot and used for controlling the action of each motor.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several equivalent substitutions or obvious modifications can be made without departing from the spirit of the invention, and all the properties or uses are considered to be within the scope of the invention.
