AI Technical Summary
Existing visual-tactile sensors suffer from insufficient light intensity of the illumination source and inconvenient assembly of various components, which affects image acquisition quality and the miniaturization design of the sensor.
The dimming assembly includes a support frame, a light source, and a light guide element. The light source is located on the side of the support frame away from the light-transmitting plate, and the light guide element passes through the light-transmitting plate to form a light transmission path. The support frame and the light-transmitting plate are detachably connected to form a modular integrated unit, ensuring uniform light distribution and stable transmission.
It improves the accuracy of image acquisition and the sensor's judgment of contact force and object shape, realizes the miniaturization and convenient assembly of the sensor, and reduces assembly complexity.
