Fixed monitoring equipment is easily limited by the angle of view and cannot effectively cover the dead angle area. Manual patrol has the problems of high labor cost and low efficiency. Wheeled patrol robots can realize automatic patrol, but they are often limited in complex terrain and are difficult to deal with uneven ground, narrow space and park lawn area. In view of these limitations, there is an increasing demand for security equipment with stronger environmental adaptability, concealment and continuous patrol capability in the market. Especially in places with complex terrain such as parks, industrial plants, logistics warehouses and other places with high security requirements, traditional security methods cannot meet the monitoring needs of all directions without dead angles. Therefore, the existing security patrol equipment has the problems of limited performance and insufficient concealment when facing complex terrain, especially at night.

[0037] Please refer to Figure 6 , the lower end of the lifting plate bar 153 is fixed with a lower half connecting rod 154, and the two ends of the lower half connecting rod are provided with a lower half deformation shell 155.

[0038] Please refer to Figure 7 , the power output end of the walking step motor 11 is fixed with a main drive gear 112, the main drive gear 112 is engaged with two auxiliary drive gears 113, the auxiliary drive gears 113 are fixed on the drive wheel disc 161 of the five-bar mechanism 16, and each drive wheel disc 161 drives two sets of five-bar mechanisms 16, one set is arranged in the inner shell 4 and the other set is arranged in the outer shell 3.

[0039] Please refer to Figure 10 , the main drive gear 112 and the auxiliary drive gear 113 are located between the inner shell 4 and the outer shell 3.

[0040] Please refer to Figures 7-9 , the five-bar mechanism 16 includes a drive wheel disc 161, a first rod 162, a second rod 163, a third rod 164 and a foot rod 165, one end of the first rod 162 is connected with the outer shell bottom end shaft hole 31, the other end is connected with the middle part shaft hole 1641 of the third rod, one end of the second rod 163 is connected with the outer shell upper end shaft hole 32, the other end is connected with the top end shaft hole 1651 of the foot rod, one end of the third rod 164 is connected with the drive wheel disc 161, and the other end is connected with the lower shaft hole 1652 of the foot rod. The connection mode involved in the five-bar mechanism is all shaft bearing connection.

[0041] Please refer to Figures 7-10 , when the device uses eight-foot five-bar mechanism to walk, the walking step motor 11 transmits power to the main drive gear 112, the main drive gear 112 transmits power to the two auxiliary drive gears 113 engaged with it, the auxiliary drive gears 113 are fixed with the drive wheel disc 161 through key connection, so as to realize that one walking step motor 11 drives two drive wheel discs 161, the two ends of the drive wheel disc 161 are connected with the third rod 164 through crank structure, so as to realize that one drive wheel disc 161 drives two sets of five-bar mechanisms 16, one set of five-bar mechanism 16 can drive one foot of the eight-foot, the whole device is provided with two walking step motors 11, and the eight-foot five-bar mechanisms driven by the two walking step motors 11 are symmetrically arranged in structure.

[0042] The principle of the specific five-bar mechanism is described in detail in Figures 7-10 When power is transmitted to the driving wheel 161, refer to Figure 10 The foot bar freedom can be calculated: this mechanism has five movable bars, which are the driving wheel 161, the first bar 162, the second bar 163, the third bar 164, and the foot bar 165. Therefore, this mechanism includes five movable bars plus the frame, i.e., the inner shell 4, a total of six components, and the total component number n = 6; the number of low pairs in this mechanism is the number of rotating pairs. Since this mechanism does not involve composite hinges, the number of low pairs is the number of hinges, a total of 7 hinges, j1 = 7; there is no high pair in this mechanism, so j2 = 0; the freedom F = 3(n-1)-2j1-j2 = 1. The freedom of this mechanism is 1, and this single freedom mechanism can control the movement of the entire mechanism by driving one of the bars, i.e., the driving wheel 161, so the active rotation of the driving wheel 161 can control the regular movement of the foot bar 165. The foot bar 165 has a roughly irregular elliptical one-way rotation, and the entire robot has eight five-bar mechanisms 16 that can be driven together to achieve eight-legged five-bar walking.

[0043] Please refer to Figure 1 , Figure 4 and Figure 5 When the device is turning, the two walking stepper motors 11 and the two rolling stepper motors 31 can be controlled separately by the electronic control element 14 and the remote control system. First, the two rolling stepper motors 31 are controlled by the remote control to lift the two opposite swing bars 32 to be perpendicular to the main shell 1, and then the two walking stepper motors 11 are controlled in opposite directions to achieve turning in place. The control terminal of the staff can receive real-time images transmitted by the night vision camera 25, and the staff can determine the direction and image information through real-time images.

[0044] Please refer to Figure 12 When the device needs to go downhill, travel straight on flat ground, or get stuck in complex terrain, it can be deformed into a low-power rolling shape. The staff can control the strong torque stepper motor 15 to drive the deformation driving rod 151 to rotate by remote control, and the sliding block 152 slides in the guide rail of the lifting plate 153 until the deformation driving rod 151 is perpendicular to the guide rail of the lifting plate 153, and the deformation is completed. At this time, the device will roll down the hill under the action of gravity to achieve the purpose of reducing power consumption; if the device needs to actively roll on flat ground, the staff can control the device to deform on flat ground by remote control, and then control the two rolling stepper motors 31 to actively rotate by remote control. The rolling stepper motor 31 drives the opposite swing bar 32 to rotate clockwise, and the opposite swing bar 32 will contact the ground, causing it to stop rotating clockwise. At this time, the rolling stepper motor 31 fixed to the outer shell 3 will rotate counterclockwise due to the reaction force, thereby driving the entire device to actively roll forward.

[0045] Please refer toFigure 4 When the device is performing monitoring operations, the night vision camera 25 will transmit real-time image information to the control terminal where the staff is located through the electronic control component 14. The staff can use remote control to control the horizontal steering stepper motor 22 to make the night vision camera chassis 23 turn horizontally. The staff can also use remote control to control the vertical flip stepper motor 24 to make the night vision camera 25 continue to flip up and down, thereby realizing monitoring with real-time adjustable angles.

[0046] This stealthy campus patrol and monitoring robot is primarily designed for nighttime campus patrol and surveillance. To ensure its stealth and minimal disruption to the environment, the robot is not equipped with any lighting. Instead, it features a highly sensitive night vision camera, enabling effective monitoring in low-light or even no-light environments, ensuring security and covert patrols at night. Furthermore, the night vision camera enables the robot to accurately identify and record potential anomalies without relying on external light sources.
