A ball net structure arranged to be portable, collapsible, and able to be configured into different arrangements for different nets and/or different sports-related activities. The ball net structure comprising a base structure including at least one support portion, at least one base extension, and at least one base extension hinge, wherein the at least one support portion and the at least one base extension are coupled to the at least one base extension hinge. At least one rod is removably coupled to the base structure and received by a net, wherein the net is adapted to exert a force on the at least one rod causing the at least one rod to exert a force onto said base structure.

A net system comprising a first net module including a first housing, a first net and a first connector connected to the first net. The first net being retractably connected to the first housing. The net system additionally includes a second net module including a second housing, a second net and a second connecter connected to the second net, the second net being retractably connected to the second housing. The first connector is connectable to the second connector to detachably connect the first net module to the second net module.

The scorekeeping system includes a plurality of scoring elements. An upper bracket can be secured a first string having a first portion of the plurality scoring elements and a second string having a second portion of the plurality of scoring elements. The first string can have a first thread and a second thread, each of the first thread and the second thread being threaded through the first portion of the plurality of the scoring elements. The second string can have a third thread and a fourth thread, each of the third thread and fourth thread being threaded through the second portion of the plurality of the scoring elements.

A method and automatic ball machine comprise an imaging system, a ball launching system, a mobility system, and a controller. The imaging system produces image data related to an environment of the automatic ball machine including a player to receive a ball. The ball launching system launches the ball to place the ball at a location proximate to the player. The mobility system automatically moves the automatic ball machine about the environment to change a trajectory of the ball based on the image data. The controller detect a location of the automatic ball machine relative to the environment based on the image data, adjust the ball launching system to place the ball at the location proximate to the player based on the image data, and control the mobility system to automatically move the automatic ball machine about the environment based on the image data.
