The utility model provides a small visual holder system, which belongs to the technical field of visual holders and is provided with a base and a shell, and the shell covers the base and is connected with a visual camera groove; an elliptical groove is formed in the shell; a supporting plate is arranged at one end of the base, a holder support is hinged to the supporting plate, a visual camera is arranged at the other end of the holder support, and the visual camera extends out of the oval groove; one end of the base is provided with a motor, the output end of the motor is connected to the connecting rod mechanism, and the other end of the connecting rod mechanism is connected to the pan-tilt support. According to the small visual pan-tilt system, the angle of the camera can be effectively adjusted, the equipment structure is compact, the internal space of the shell is remarkably saved, and the overall size of the system is smaller; the device is especially suitable for small visual camera equipment, and is simple in structure, convenient to maintain and low in manufacturing and using cost.

This invention relates to the field of robot control technology, specifically disclosing a vision-gimbal coordinated laser pointing device and control method for a quadruped robot. The device includes a depth camera mounted on the robot's head, a two-dimensional gimbal on its back, and a control module. The depth camera acquires the target's three-dimensional coordinates. The two-dimensional gimbal consists of a yaw servo and a pitch servo, with a laser mounted at its end. The control module calculates the target's yaw and pitch angles in real time based on a pre-calibrated rigid body transformation relationship between the camera and gimbal coordinate systems, driving the gimbal to move and precisely point the laser beam at the target. This method achieves closed-loop control through "detection-coordinate transformation-angle calculation-servo control." The system incorporates a dynamic compensation mechanism that continuously corrects the gimbal angle during the quadruped robot's movement, stably tracking the target and effectively overcoming pointing deviations caused by robot vibration, significantly improving pointing accuracy and reliability in dynamic scenarios such as inspection and security.
