System and method for launching a ball onto the ground of a playing field. The system includes an outlet chamber configured to receive the ball therein; an outlet conduit or frame configured to contain the outlet chamber and allow the same to move through the outlet conduit towards a second position on the ground; movement capability of the outlet chamber, connected to and configured to move the outlet chamber between at least the first position and the second position, where the outlet chamber includes an outlet mouth and launching means for launching the ball arranged in the outlet chamber. A field including the system is also described.

The utility model discloses an automatic ball launcher. The automatic ball launcher includes a ball launcher shell, in which an accommodating space is arranged; a ball launching channel, arranged in the accommodating space and provided with a ball launching inlet and a ball launching outlet; an acceleration mechanism, arranged in the accommodating space for pushing and accelerating the ball that enters the ball launching channel to a preset speed; and a ball launching mechanism, arranged in the accommodating space and close to the ball launching outlet for receiving the ball that is pushed by the acceleration mechanism and launching the ball from the ball launching outlet to the outside of the ball launching channel. The utility model can launch the ball more stably.

A projection system includes a control module, a projection tube, an aiming driver, an observation device and an observation driver. The control module is configured to issue a first control command and a second control command. The aiming driver is electrically connected to the projection tube and configured to control, in response to the first control command, a projection viewing-line of the projection tube to be aligned with a calibration point. The observation driver is electrically connected to the observation device and configured to control, in response to the second control command, an observation viewing-line of the observation device to be aligned with the calibration point. The projection tube and the observation device are controlled asynchronously.

The present invention relates to an improved ball tossing device that is portable and adjustable to accommodate a variety of different balls and lobbing preferences. This may be achieved through various features including some or all of the following: a ball feeding mechanism using a rotating disk with an offset feed channel to deliver balls to the ball tossing queue; a catapult arm that uses a motor/spring mechanism to toss balls in the queue out of the machine; an indexer feature for isolating the ball to be tossed from the other balls in the queue; and adjustable features that allow users to vary ball trajectory of the ball being tossed.

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.

A softball pitching machine in accordance with the present disclosure is configured to lob a softball along an arcuate path with forward spin to mimic the motion of an underhand, slow pitched softball from a human pitcher. The softball pitching machine includes a throwing arm having a curved hand configured to move along a predetermined arcuate path to a preset stopping point that imparts the arcing path and the forward spin on the softball.
