A system includes a blocking machine having at least one court detection device and at least one robotic blocker simulating human movement relating to a sport. Images captured from the at least one court detection device are utilized for determining a speed, trajectory, and/or position of a sports ball. Based on the determined speed, trajectory, and/or position of the sports ball, rotational and/or translational movement of the robotic blocker simulates a human blocker attempting to block the sports ball.

A ball game is submitted. The ball game has an elevated, flat surface which resembles a volleyball net, but where there are three rows of ten boxes. Each hole (box) in the net is 12 inches12 inches, and the game ball is around 5 inches in diameter. A user stands on either side of the elevated, flat surface and may throw the ball through one of the holes (boxes) in the elevated, flat surface. Another user stands on the opposite side of the elevated, flat surface and may catch the ball and return it in the same way. The height of the elevated, flat surface which resembles a volleyball net, the number, and dimensions of the holes (boxes), and the size of the game ball may be changed/adjusted. However, the holes (boxes) in the net are at least 50% larger than the diameter of the game ball, e.g., in another embodiment, there are three rows of eight boxes, where each hole (box) in the net is 14 inches14 inches, and the game ball is around 6 inches in diameter.

A volleyball training system incorporates a training volleyball with ball attachment panels with ball hook-and-loop fastener exposed for detachable attachment of a tether panel by the panel hook-and-loop fastener. The tether panels have an attachment side with the panel hook-and-loop fastener and an exposed side having a tether coupler, such as a tether coupler loop configured to detachably attach with a tether. A single tether may be attached to one of the tether panels and may be attached to a belt, or two tethers, such as suspension tethers may be coupled to two separate tether couples, preferably on opposing sides of the training volleyball to enable the training volleyball to be suspended from supports. The detachable tether couplers enable a person to use the training volleyball for normal play with the tether panels removed. A variety of volleyball hitting types may be practiced with the volleyball training system.

A volleyball trainer, and more particularly, a volleyball trainer that is adjustable to various heights, hoop sizes, and hoop angles to accommodate different training drills such as volleyball setting, passing, spiking, or bumping, is disclosed. The volleyball trainer enables players to hone their volleyball skills alone and at any time regardless of their levels of expertise. For beginners, the hoop of the volleyball trainer can be expanded to a larger perimeter. More advanced volleyball players can adjust the hoop to have a smaller perimeter. By enabling adjustment of the hoop angle and height, the volleyball trainer can accommodate multiple sports and practice drills. An elongated net that exits into a volleyball bag ensures that successful volleyball hits are easily retrieved for continuous practice. The volleyball bag is also a convenient carrying case for volleyballs or other balls after use because it is detachable from the base of the volleyball trainer.

A volleyball training device, including: a mounting mechanism, a collection mechanism and a ball-control mechanism. The mounting mechanism is configured to secure the volleyball training device to a position for use. The collection mechanism is configured to receive and temporarily store balls. The ball-control mechanism and/or the collection mechanism are connected to the mounting mechanism, and the ball-control mechanism is located below the collection mechanism. The ball-control mechanism includes a ball-control assembly and an abutment member, and the ball-control assembly defines a spiking position and configured to position a first ball the abutment member rotatably connected to the ball control assembly and configured to selectively abut or release a second ball from the collection mechanism; when the first ball is spiked and moves out of the spiking position, the abutting member rotates from an abutting state to a released state, allowing the second ball to descend to the spiking position.

A volleyball training apparatus is provided for simulating blocking, setting, and other training scenarios. The apparatus includes a mobile base with lockable wheels, optional storage compartments, and a vertical frame supporting a forward-facing mounting plate. The mounting plate is vertically adjustable by a worm-gear crank and cable system with self-locking features, or by alternative pin-and-hole or friction mechanisms. The plate may also tilt forward or backward using manual locking elements to replicate realistic game conditions. One or more arm replicas are mounted to the plate and may be repositioned laterally to simulate different formations. The adjustable height, tilt, and arm positioning enable rapid reconfiguration, allowing coaches to efficiently conduct diverse offensive and defensive training drills.
