This utility model discloses a liquid connector, which includes a female connector, a male connector, and a gasket. One end of the male connector is installed with the female connector. The outer wall of the male connector has an adjusting ring surface that surrounds it, and the adjusting ring surface is a convex arc surface that protrudes outward. The gasket is sleeved on the male connector, and the inner wall of the gasket has a mating surface that mates with the adjusting ring surface. The gasket has a first state and a second state. In the first state, the mating surface abuts against the adjusting ring surface at a first contact position, so that the male connector maintains a first angle. In the second state, the mating surface abuts against the adjusting ring surface at a second contact position different from the first contact position, so that the male connector maintains a second angle different from the first angle. Through the design of the guide sleeve, the problem of misalignment and displacement that easily occurs when the male and female connectors are docked underwater is effectively overcome, and the convenience and success rate of the docking operation of the male and female connectors are significantly improved.

The embodiment of the invention provides a robot eyeball tracking control method and device, computer equipment, a computer readable storage medium and a computer program product, and belongs to the technical field of robots. The robot eyeball tracking control method comprises the following steps: determining a three-dimensional pose of a target object in a current camera coordinate system by using a binocular camera, and determining an expected camera extrinsic parameter of the target object at a target position based on the three-dimensional pose; obtaining current steering engine control data of eyeballs of the robot, and determining current camera external parameters from a pre-constructed mapping relation table based on the current steering engine control data; and determining the difference between the expected camera external parameter and the current camera external parameter, determining a steering engine control instruction of the robot eyeball at the next moment based on the difference and the mapping relation table, and driving the robot eyeball to move based on the steering engine control instruction. According to the technical scheme, the control problem caused by mechanical uncertainty of the composite steering engine can be effectively solved, and high-precision tracking control over the object by the eyeballs of the robot is achieved.

This invention discloses a 3D printing platform leveling and printing quality monitoring system and method based on vision and laser fusion detection. The system includes a vision detection module, a laser ranging module, a fusion calculation module, an AI recognition and decision-making module, and a control feedback module. Both the vision detection module and the laser ranging module establish bidirectional communication connections with the fusion calculation module to match the timing of image and distance information acquisition. This application effectively solves the problems of insufficient accuracy and instability in traditional technologies. By constructing a collaborative detection structure through the vision detection module and the laser ranging module, a triangulation subsystem of laser and vision detection modules is formed, completely overcoming the inaccuracy problem of traditional probes on highly reflective surfaces or magnetic plates. Simultaneously, it avoids the interference of environmental temperature, humidity, and material properties on measurement accuracy, significantly improving the stability and accuracy of the detection.
