An apparatus for racket sports practice (such as tennis, pickle ball, padel, squash, racquet ball, table tennis and the like) is disclosed. The apparatus being comprised of a tubular frame, lightweight cloth, a swivel bounce board and unique side shields that prevent balls from straying. The curved area of the rebound sheet allows users to hit balls into the apparatus and have them returned at various speeds and angles. The apparatus being of such a size that, when broken down after practice, can be easily transported by a single person. An object of the invention is to provide an affordable means for racket sports enthusiasts to practice independently.

Systems, methods, and computer-readable media are disclosed for autonomous tennis assistant systems having autonomous ball machines such as an autonomous and interactive tennis ball ejection robot. Example methods include determining, by a device, the position of a first player on a tennis court, determining a first target location for a first tennis ball to be ejected toward the first player, generating a trajectory for the first tennis ball to reach the first target location, and causing ejection of the first tennis ball from the tennis ball ejection robot along the generated trajectory toward the first target location. A base station may be used to provide image data for use by the tennis ball ejection robot from one or more additional vantage points.

A device for practicing hitting a ball may comprise a bat and a flag portion. The bat may comprise a bat stick comprising a bat handle and a bat barrel coupled to the bat handle; and a weight coupled to the bat barrel. The bat may comprise a rigid material. The flag portion may comprise a flag coupled to the bat barrel, wherein the flag is configured to extend from the bat barrel. The flag may comprise a flimsy material.

An apparatus includes a training area in the form of an enclosed space in which light levels can be controlled, at least one physical element related to a task for which an individual is to be trained, and a lighting arrangement. The lighting arrangement generates a background luminance level in the training area sufficient to cause the vision system of the individual to function in the mesopic or low photopic range of vision, and the physical elements are themselves illuminated by an illumination means. The luminance level of the physical elements is greater than the background luminance level.

A smart ball-machine uses artificial intelligence to train a player or to play with a player. For example, the ball-machine can adjust the tennis ball speed, topspin, bounce according to the player's successful ball return rate. The ball-machine can be preconfigured with a profile of a player. For example, the ball-machine may download a complete profile of a tennis player from a game recording, or may download a file with a customized profile of a player to train a player using the ball-machine. The ball-machine is equipped with a plurality of wheels, motors, and shafts to provide a fully customizable launch of one or more balls. For example, the ball can be launched from the machine from one side of a tennis court to another side of a tennis court with a variety of speeds, trajectories, topspin, bounce etc.
