A bionic vision platform driven by multi-axis linear motor

Abstract

The invention provides a bionic vision platform driven by a multi-axis linear motor, including a host, a motion control card, a motion mechanism, a camera and an image acquisition card. The above-mentioned parts are connected in series to form a closed loop, and the host controls the motion mechanism through the motion control card. , the motion mechanism drives the camera to rotate, the camera collects images, and outputs them to the host computer through the image acquisition card. The motion control card controls the movement of the vertical and horizontal linear motors. The mover of the horizontal linear motor is vertically fixed to the stator of the vertical linear motor. The connecting block is connected to the mover of the vertical linear motor. Two connecting rods are arranged in parallel. One end of the connecting rod is connected with the connection block, and the other end is connected with the camera. The platform controls the two degrees of freedom of the bionic eye through two linear motors, and the rapid movement of the two linear motors ensures that the camera can capture dynamic objects and targets, and can well complete various posture adjustments of the bionic eye, and is capable of dealing with complex work requirements in the environment.
