The invention discloses a three-freedom-degree binocular bionic mechanism which comprises an installing rack, two eyeballs of the same structure, two photographing devices and two three-axis motor drivers. Each eyeball is a spherical cavity. Three motors are installed outside each eyeball. The three motors of each eyeball are located in the X-axis direction, in the Y-axis direction and in the Z-axis direction of the eyeball. The front half portion of each eyeball is provided with one photographing device which is located in the direction opposite to the Y-axis direction. Each three-axis motor driver is connected with the three motors outside the corresponding eyeball. The three-freedom-degree binocular bionic mechanism has the beneficial effects that the structure is simple, the integration level is high, and leftward-rightward movement freedom degree, rotation movement freedom degree and pitching movement freedom degree can be achieved. Through the arrangement of the three installing axes, omni-directional image capture can be achieved; through the arrangement of two cameras, the positioning accuracy of bionic eyes can be improved.
Description
technical field [0001] The invention relates to the technical field of bionic robots, in particular to a three-degree-of-freedom binocular bionic mechanism. Background technique [0002] As we all know, eyes are one of the most important organs of human beings, and more than 90% of the information that human beings perceive the objective world is obtained through eyes. For bionic robots, "eyes" are also an important perception device, so the study of robotic bionic eyes is a research hotspot in the field of robotics today. [0003] In the animal world, the visual range of the two eyes of animals is divided into different sizes. Some animals have two eyes that are far apart and have a relatively large visual range, which can monitor attackers in a wide range, such as chickens and horses, etc.; while some animals have two eyes. The eyes are relatively concentrated, the visual range is relatively small, the positioning is precise, and the specific position of the prey can be o...
