A method of providing a sports participant on a playing surface with a towel during play includes providing a robot having a towel dispenser or a towel holder holding a towel, a robot controller, and a means responsive to the controller for driving and maneuvering the robot; positioning the robot at a first location off the playing surface at a standby location; directing the robot via control commands to move from the standby location toward the playing surface to provide the towel; and directing the robot via control commands to return to the standby location.

Disclosed is an intelligent learning and adjustment system for a tennis training robot, including an image recognition system, an algorithm model, a back-end processing platform, and an optimization model. Preprocessing of incoming ball data is performed, various necessary data, such as speeds and directions of flying tennis balls, spinning and placements, are collected, various data sets are processed by using various machine learning algorithms, effective predictions and decisions are generated to facilitate the prediction of the placement and difficulty level of the incoming ball, so that a capability and level of a sparring athlete can be evaluated, the tennis training robot accordingly makes prediction and recognition, and carries out interactive feedback actions in a timely manner. The entire training process involves continuously updating of weights and bias values to make the predictions increasingly accurate, and the tennis training robot can provide an interactive intelligent training method.

An AI-assisted mobile tennis training system integrates a motorized ball delivery device, multi-camera vision, autonomous navigation, and artificial intelligence for adaptive, data-driven player development. The device includes a motorized chassis, ball hopper, programmable ball delivery mechanism with variable spin, speed, and trajectory control, and a navigation subsystem employing omnidirectional wheels and localization based on court line recognition. A multi-camera array captures real-time player and ball movement, while onboard and remote computing modules process the data to determine player position, shot type, and performance metrics. An AI model predicts optimal ball delivery parameters and adapts drills based on player progress. A mobile application provides remote control, drill customization, and performance analytics. The system supports autonomous repositioning, safety monitoring, and individualized training plans, enabling dynamic, responsive, and efficient tennis practice for skill acquisition and improvement in both amateur and professional players.

A method, apparatus, and system are disclosed for a robot with tennis ball gathering capabilities. A robot is configured to collect, transport, and deposit for storage tennis balls and other light-mobile sports equipment such as are used in table tennis, badminton, squash, pickleball, golf, basketball, dodgeball, floor hockey, indoor soccer, etc., to assist a player in practice without need for additional support personnel or manual ball retrieval by the player.

An apparatus for target shooting includes a motorized carriage, a target mount configured to support a target, and a dummy that serves as the target for firearm projectiles. The carriage includes an assembly of metal and/or heavy duty plastic parts forming a frame, a motor box, and mounting surfaces and attachment points for the carriage electrical and electronic components and drive system. The drive system includes a motor mechanically connected to one or both of a front and rear axle, to which wheels are mounted. The drive system may include or be in signal communication with a wireless receiver or transceiver that receives control signals from a remote controller. The target mount may comprise metal members including a base member attached to the frame of the carriage, a pole attached to the base member and extending upward therefrom, and a mounting assembly attached at the top of the pole.

An entertainment system including at least one support pole, at least one attachment cord, a motor, wherein the motor is associated with the support pole and the attachment cord and a target, wherein the target is connected to the attachment cord, and wherein the motor is operable to cause the target to move in at least one of a vertical direction, a horizontal direction and a circular direction relative to the at least one support pole via the attachment cord.
