Abstract

The invention relates to a parallel type three-degree-of-freedom bionic eye device. The parallel type three-degree-of-freedom bionic eye device comprises a sensor component. A base plate is fixed below the sensor component; a connecting rod assembly comprises three upper connecting rods and three lower connecting rods, one end of each upper connecting rod is connected with the base plate, and the other end of each upper connecting rod is connected with the upper end of the corresponding lower connecting rod; a rotating disc assembly sequentially comprises a first rotating disc, a second rotating disc and a third rotating disc from top to bottom, the outer surfaces of the three rotating discs are respectively connected with the lower ends of the lower connecting rods, an upper fixing base is arranged above the first rotating disc, and a lower fixing base is arranged below the third rotating disc; and a motor assembly is arranged below the lower fixing base and comprises three motors, the motors penetrate through the lower fixing base to extend into the three rotating discs correspondingly, and the motors are rotationally connected with the three rotating discs correspondingly. The parallel type three-degree-of-freedom bionic eye device is convenient to miniaturize, small and compact in size and low in cost. Meanwhile, the parallel type three-degree-of-freedom bionic eye device has the advantages of being high in motion precision, high in response speed and the like.

Description

technical field [0001] The invention relates to the field of bionic robots, in particular to a parallel three-degree-of-freedom bionic eye device. Background technique [0002] The bionic eye is an artificial visual system constructed by simulating the visual system of animals. It is an important sensory device for obtaining objective world information for robots, just as the eyeball is for human beings. Improving the performance indicators of bionic eyes, such as control accuracy and sensor data processing, can make robots better used in production and life processes. [0003] As a movable sensing system, the current implementation methods of bionic eye devices mainly include series structure scheme (CN201810107465.5), parallel structure scheme (CN 201610292738.9) and series-parallel combination structure scheme (CN201610846074.6). The structure and motion control strategy of the serial structure scheme are relatively simple, but it is difficult to miniaturize, and the dir...

AI Technical Summary

Problems solved by technology

The structure and motion control strategy of the serial structure scheme are relatively simple, but it is difficult to miniaturize, and the direct drive scheme of the motor has high requirements on the performance of the motor

The parallel structure scheme is based on magnetic levitation drive. For the current magnetic levitation technology, the threshold is very high and the equipment cost is high.

The structural scheme of series-parallel combination is large in size, and there are many accessories around the eyeball, which is not conducive to integration into the robot
