A golf club for improving the training of young children is provided, comprising a grip, a shaft, and a head. The head is oversized, having a volume of about 1100 to about 1400 cubic centimeters. The ratio of the distance between the swing weight, the balance point of the club, and the grip butt portion to the overall length of the club, and / or the ratio of the overall mass of the club to the distance between the balance point of the club and the grip butt portion, are designed to improve the application for young children. A golf training system is also provided, comprising a golf club and a corresponding training glove.

The application discloses a water sports multi-dimensional motion control method and device, comprising: identifying the periodic deviation of the rowing path according to the paddle handle rotation angular velocity, the trajectory curvature radius and the deviation angle; triggering the rotation radius determination reference update when the deviation angle exceeds the standard range to obtain the adjusted rotation radius determination reference; determining the balance point of the power stroke length extension and the arc trajectory curvature according to the adjusted rotation radius determination reference, and obtaining the paddle handle rotation radius set value corresponding to the balance point; evaluating whether the corresponding proportion of the direction deviation angle and the work stroke length meets the efficiency stable output requirement, identifying the real-time adjustment feedback of the rotation angular velocity after the improvement of the rower's body coordination, and obtaining the stable output level of the propulsion efficiency; and updating the monitoring period of the trajectory curvature radius according to the ship body posture sensing module to maintain the continuity of the holding stability, the power rhythm coherence and the trunk rotation amplitude at the optimal balance point.

This invention discloses a robot balance control method and apparatus, relating to the field of robotics, to ensure the balance of a robot when performing multiple coordinated actions. This application separately calibrates the independent dynamic balance points for each independent action performed by the robot. Based on these independent dynamic balance points, a comprehensive dynamic balance point for the robot performing a composite action is determined. According to a set static balance point, it is determined whether the comprehensive dynamic balance point exceeds the range constrained by set balance limitations. If so, a compensation action is determined based on the difference between the comprehensive dynamic balance point and the static balance point. This compensation action is used to compensate for the imbalance at the comprehensive dynamic balance point, thereby balancing the robot. This application solves the imbalance problem when multiple independent actions are linked, and features strong scalability and a good user experience.

This invention provides a novel badminton racket design, including an adjustable handle for shaft curvature and balance point, and a double-layered frame. The adjustable handle addresses the limitation of traditional badminton rackets in adjusting shaft stiffness and balance point, allowing users to fine-tune the racket to suitable parameters. The double-layered frame solves the problems of insufficient stability in traditional aerodynamic frames and slow swing speed in box-type frames.
