[0037] Reference Figures 1 to 6 , a four-legged mechanical dog, comprising: a body 1, mechanical legs 2 and a master control system;
[0038] In one embodiment, referring to Figure 1-Figure 2As shown, the mechanical foot 2 is provided with four groups of mechanical feet 2 symmetrically arranged front to back and left to right, and each group of mechanical feet 2 is independent of each other; the body 1 includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are detachably connected; the mechanical foot 2 includes a driving component 21, a leg structure 22 and a walking wheel 23, the output end of the driving component 21 is fixedly connected to the leg structure 22, the walking wheel 23 is rotationally connected or limit-connected to the leg structure 22, and the driving component 21 is fixedly connected to the lower shell 12; the master control system includes a control unit, and the control unit can send a control signal to the driving component 21.
[0039] Among them, by setting four sets of independent mechanical feet 2, the swing amplitude of each set of mechanical feet 2 is controlled by the master control system, so as to realize the transformation of various motion postures. The four-legged mechanical dog has the characteristics of transforming various motion postures and realizing complex operation actions.
[0040] In one embodiment, referring to Figure 3 As shown, the driving assembly 21 includes a motor and a positioner. The motor is connected to the positioner. The motor controls the swing amplitude of the leg structure 22 through the rotation of the positioner; the swing amplitude is 360°.
[0041] In one embodiment, referring to Figure 4 As shown, the mechanical dog also includes a power supply component, which includes a power switch 3 and a power supply component, and the power switch 3 is connected to the power supply component. The power supply component includes a battery compartment 4 and a charging interface 5, and the battery compartment 4 is connected to the charging interface 5.
[0042] In one embodiment, when the leg structure 22 swings from the back to the front, the running wheel 23 rolls and rotates forward to reduce the resistance of the swing. When the leg structure 22 swings from the front to the back, the running wheel 23 stops rotating to increase the thrust of the ground on the running wheel 23, and the vehicle travels by utilizing the difference in the force of the ground on the running wheel 23 swinging in two directions.
[0043] In one embodiment, the master control system further includes a remote controller, which is connected to the control unit. The remote controller includes a number of buttons, which correspond to various actions. When one of the buttons is pressed, the control unit controls the rotation of the motor and the positioning angle of the positioner to control the swing amplitude of the leg structure 22 to achieve the action corresponding to the button. The buttons include: conventional walking operations such as forward, left turn, right turn; and also include various complex movement postures such as sitting down, lying down, shaking hands, greeting the New Year, peeing, dancing, yoga, acting like a spoiled child, handstand, push-ups, playing dead, surrendering, etc.
[0044] In one embodiment, referring to Figure 5As shown, when the operator presses the handshake button in the remote control, the control unit receives the handshake signal from the handshake button and transmits the handshake signal to the motor and positioner of the right front mechanical foot 2. After the motor and positioner receive the handshake signal, the motor is started to drive the foot structure 22 to start swinging. The positioner sets the positioning angle and limits the swing amplitude of the foot structure 22 to 110°, so as to achieve an action similar to the handshake of the mechanical dog.
[0045] In another embodiment, referring to Figure 6 As shown, similar to the operation of shaking hands, by pressing the sit button in the remote control, the operator presses the sit button in the remote control, and the control unit receives the sit signal sent by the sit button, and transmits the sit signal to the motors and positioners of the two sets of rear mechanical feet 2. After the motors and positioners receive the sit signal, the motors are started to drive the foot structure 22 to start swinging, and the positioners set the positioning angle, limiting the swing amplitude of the foot structure 22 to 30°, so as to achieve an action similar to that of the mechanical dog sitting down.
