The swing here can be up and down swing or left and right swing. The synchronous transmission component is connected to the output end of the first joint module 1 and the side wall of the second joint module 2. The first joint module 1 rotates forward or reversely.

The swing here can be an up-and-down swing or a left-and-right swing.

The first joint module 1 rotates forward or reversely, and the second joint module 2 can be driven by the synchronous transmission component to rotate around the connection axis between it and the first mounting seat 3, which is equivalent to driving the second joint module 2 to rotate around the joint axis of the first joint module 1, thereby controlling the second mounting seat 4 connected to the second joint module 2 to rotate around the joint axis of the first joint module 1 to perform wrist flexion and wrist extension movements, thereby realizing a swing similar to that of a human ankle joint. The swing here can be an up-and-down swing or a left-and-right swing. Wherein, the rotation of the joint axis of the first joint module 1 is defined as an up-and-down swing, and the rotation of the joint axis of the second joint module 2 is defined as a left-and-right swing; and the same is also true in reverse.

[0119] In this example, the second joint module 2 can be used to control the second mounting seat 4, thereby achieving a sideways swing similar to that of a human ankle joint, making motion control simpler. The second joint module 2 and the first joint module 1 are arranged in a synchronous linkage manner to achieve a staggered arrangement of the first joint module 1 and the second joint module 2, making the structural space more reasonable. The first joint module 1 drives the second joint module 2 to rotate around the first direction through the synchronous transmission component, thereby driving the second mounting seat 4 to rotate, so as to achieve an up and down swing similar to that of a human ankle joint. The cooperation between the first joint module 1 and the second joint module 2 gives the transmission device two degrees of freedom, making it more flexible, with a wider range of motion and more human-like.

[0120] As an example, the output end of the connecting joint assembly is connected to the fixed end of the transmission device, and the movement of the transmission device can be controlled by connecting the joint assembly; when the transmission device is set as an ankle joint, the connecting joint assembly can be a knee joint or a hip joint. Different combinations can be designed according to actual needs.

[0121] In one embodiment, as an example, the connecting joint assembly includes a first sub-joint and / or a second sub-joint. When the transmission device is an ankle joint, the first sub-joint is a knee joint, and the second sub-joint is a hip joint. When the connecting joint assembly includes only the first sub-joint, the output end of the first sub-joint is connected to the fixed end of the transmission device, and the fixed end of the first sub-joint is used to connect to the structure to be installed 18. The movement of the transmission device is controlled by the first sub-joint, that is, the movement of the ankle joint is controlled by the knee joint. When the connecting joint assembly includes only the second sub-joint, the output end of the second sub-joint is connected to the fixed end of the transmission device, and the fixed end of the second sub-joint is used to connect to the structure to be installed 18. The movement of the transmission device is controlled by the second sub-joint, that is, the movement of the ankle joint is controlled by the hip joint. Alternatively, the output end of the first sub-joint is connected to the fixed end of the transmission device, the fixed end of the first sub-joint is connected to the output end of the second sub-joint, and the fixed end of the second sub-joint is used to connect to the structure to be installed 18. In other words, the movement of the ankle joint is controlled by the knee joint, and the movement of both the knee and ankle joints are controlled by the hip joint.

[0122] An embodiment of the present invention provides an intelligent terminal, comprising a main body, and also comprising an intelligent service system and / or an intelligent mobile system; the intelligent service system is arranged at a first position of the main body, and the intelligent mobile system is arranged at a second position of the main body.

[0123] As an example, the intelligent terminal includes a main body and also includes an intelligent service system and / or an intelligent mobile system; the intelligent service system is set at the first position of the main body, and the intelligent mobile system is set at the second position of the main body; in this example, when the control system receives the posture change information of the mechanical actuator, the control system can calculate the updated value of the joint angle of each joint module based on the inverse kinematics of the intelligent service system or the intelligent mobile system, and then input the updated value into each joint module, so that the joint angle of the joint module reaches a predetermined position, thereby driving the posture of the mechanical actuator to change.
