Smart tennis ball machine

Abstract

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.

         7 . The ball-machine of  claim 1  further comprising a motor coupled to the wheel to rotate the wheel according to one or more settings. 
     
     
         8 . The ball-machine of  claim 1  further comprising a mechanism coupled to the bag, wherein the mechanism is configured to attach a ball holder. 
     
     
         9 . The ball-machine of  claim 1 , wherein the housing is configured to oscillate via a stage that lifts the housing. 
     
     
         10 . A ball-machine housed in a bag, the ball-machine comprising:
 a set of wheels to roll the ball-machine from one location to another location;   a housing that sits adjacent to the set of wheels;   a ball ejector inside the housing, wherein the ball ejector includes a wheel to control speed of a ball;   a memory inside the housing;   an antenna to receive data including a profile of a player;   a processor coupled to the memory, the processor inside the housing, wherein the processor is to apply artificial intelligence to the received data and to determine a control setting for the wheel;   a battery to power the processor;   an interface to charge the battery; and   a mechanism coupled to the bag, wherein the mechanism is configured to attach a ball holder.   
     
     
         11 . The ball-machine of  claim 10  further comprising a motor coupled to the wheel to rotate the wheel according to one or more settings. 
     
     
         12 . The ball-machine of  claim 10 , wherein the housing is configured to oscillate via a stage that lifts the housing. 
     
     
         13 . The ball-machine of  claim 10  further comprising a connectivity interface to connect the processor with one or more external devices. 
     
     
         14 . The ball-machine of  claim 10 , wherein the processor is to change one or more controls of the ball-machine according to a performance of a player receiving the ball. 
     
     
         15 . The ball-machine of  claim 10 , wherein the antenna is to receive the data via a smart phone. 
     
     
         16 . The ball-machine of  claim 10 , wherein a camera is coupled to the bag. 
     
     
         17 . The ball-machine of  claim 10  further comprising a ball feeder to store two or more balls, wherein the ball feeder is coupled to the ball ejector. 
     
     
         18 . A ball-machine housed in a bag, the ball-machine comprising:
 a set of wheels to roll the ball-machine from one location to another location;   a housing that sits adjacent to the set of wheels;   a ball ejector inside the housing, wherein the ball ejector includes a wheel to control speed of a ball;   a memory inside the housing;   an antenna to receive data including a profile of a player;   a processor coupled to the memory, the processor inside the housing, wherein the processor is to apply artificial intelligence to the received data and to determine a control setting for the wheel;   a battery to power the processor;   an interface to charge the battery; and   a lifting mechanism configured to lift the housing to change a position of the ball ejector.
