Problems solved by technology

[0004] The technical problem of the present invention is: to overcome the problem that the volume of the bionic eye is too large due to the large volume of the existing actuator, and replace the two single-degree-of-freedom motors with a two-degree-of-freedom electromagnetic drive rotating mechanism with few parts and simple structure. Integrated design realizes human-scale bionic eye device

Embodiment Construction

[0017] like figure 1 Shown is the structural diagram of the bionic eye device. The whole device is composed of a stator assembly and a rotor assembly. The stator assembly includes an outer spherical shell, a stator core, a stator connector, an angular displacement camera, a spherical hinge block and a winding; the rotor assembly includes a camera, Rotors, rotor attachments, ball joints and camera attachments. The four stator cores are fixedly connected with the outer spherical shell, and are evenly distributed along the large circumference of the outer spherical shell. The stator connecting piece is located at the center of the four stator cores and is used to connect and fix the four stator cores; the rotor connecting piece, the spherical hinge and the The camera connector constitutes a transmission rod, and the center of the spherical joint is located at the center of the spherical surface of the rotor, constraining the rotor assembly to move around the center of the spheric...

Abstract

The invention discloses a compact bionic eye device based on a two-degree-of-freedom electromagnetic driving rotating mechanism. The device can be used as a visual sensor of a bionic robot such as a humanoid robot and mainly comprises a rotor, a stator core, a winding, an angular displacement camera, a spherical hinge pressing block, a stator connecting piece, a camera, a spherical hinge, a cameraconnecting piece, a rotor connecting piece and an outer spherical shell. According to the device, by adjusting the winding currents of the four stators, the rotor is driven to realize limited rotation of pitching and yaw freedom; and the two-degree-of-freedom electromagnetic rotating mechanism is compact in structure, and the bionic eye device capable of realizing the human eye scale provides animportant foundation for truly applying bionic eyes to the humanoid robot.

Description

technical field [0001] The invention relates to a compact bionic eye device based on a two-degree-of-freedom electromagnetically driven rotating mechanism, which can be used as a visual sensor for bionic robots such as humanoid robots. Background technique [0002] The wide application of robots is an important pillar and development trend of industrial society. Humanoid robots imitate the results of human evolution, and have better flexibility and adaptability in cooperating with humans or replacing humans in related work. They are an important category of robots. The human eye is the most important organ for human beings to obtain information. From the perspective of imitating human beings, visual sensors will become the most important device for humanoid robots to obtain external information. The bionic eye is a visual sensor that can realize two-degree-of-freedom or three-degree-of-freedom rotational motion. By adding corresponding control hardware and processing softwa...
