Omnidirectional system for expelling and collecting balls adapted to reproduce a real playing and/or training dynamics, said system being equipped with: - at least one closing element connected to at least one expelling device of said system arranged orthogonal to said expelling device when expelling at least one ball from said system, said ball bouncing on an upper surface of said closing element going towards at least one user; - at least one net element of at least one collecting element of said system, said net element being composed of a first net element fastened on its top and side to a chassis, and on its bottom not constrained to said chassis, and of a second net element placed before said first net element and fastened on its top and side to said chassis, and on its bottom to at least one channeling means; - said at least one channeling means connected on its perimeter to the chassis, and equipped at its center with at least one opening, adapted to be connected to at least one collecting means of the expelling device for collecting the ball, said channeling means further allowing to transport said system by allowing a closure of said collecting element; said expelling device being equipped with: - at least one case equipped on its bottom with a plurality of castor wheels adapted to move said expelling device, and equipped on its front with said closing element, the lower portion of said closing element being connected to a front lower edge of said case; - said collecting means, adapted to be connected to said recess of said collecting element; - two or more propelling means, adapted to enable expelling said ball; - a plurality of motors, adapted to manage said propelling means, to rotate and to incline said expelling device; - an electric apparatus adapted to electrically and mechanically manage said plurality of motors and said propelling means, through at least one managing unit, regulating the launching speed of the ball, managing a launching timing of two or more balls, the rotation, the height and the slant of said expelling device, allowing the user to perform a different training and/or play by making it quicker or slower; and - at least one framework, adapted to include said collecting means, said two or more propelling means, said plurality of motors, said closing element, said framework being equipped on its bottom with a plurality of mechanical devices, adapted to enable the rotation of said expelling device, and on its front being equipped with at least one constraining means adapted to enable a clockwise slant of said expelling device, through said plurality of motors. - at least one closing element connected to at least one expelling device of said system arranged orthogonal to said expelling device when expelling at least one ball from said system, said ball bouncing on an upper surface of said closing element going towards at least one user;
