A tennis ball retriever for retrieving a tennis ball on and about a tennis court and for controllably releasing the ball includes a front-end ball collector having two spaced-apart blades defining a ball collection space. The retriever includes a means for gripping and securing a ball positioned at the fore end, and one or more detents for retaining the collected ball in the collection space until a programmed or manually-directed release toward a target location such as a tennis baseline. The retriever includes a processor-controller for controlling and directing the retriever during a retrieval session. The retriever may be remote-controlled such as by voice commands.

The present disclosure provides a golf club and golf club head which integrate a bottle opener mechanism onto a rear wall of the head so as to provide bottle cap removal functionality without interfering with the shape that allows players to scoop balls from the ground without bending down. The golf club head may also have a permanent magnet disposed adjacent to the bottle opener mechanism to prevent removed bottle caps from falling to the ground.

Provided is a highly reliable, cost-effective scattered object collection system that can determine the correct position of each scattered object on the ground, such as a ball, and efficiently collect scattered objects by reducing unnecessary traveling of an autonomous collector. The scattered object collection system includes an autonomous collector that performs a collecting operation by picking up balls B while traveling in a work area W and a collector management unit that manages the autonomous collector. The collector management unit acquires positional information on the autonomous collector, identifies an actual position where each ball B was picked up in the work area W using the acquired positional information, and allows the autonomous collector to perform a collecting operation in a place having a high density of balls B with higher priority than a place having a low density of balls B using the identified actual positional information on each ball B.

A ball supply apparatus includes: a housing coupled to the upper portion of the column structure, wherein a top portion of housing is partially opened, wherein the housing is divided by a partition into a ball storage portion and a ball discharge portion, wherein a bottom face of the ball storage portion is inclined downward toward the ball discharge portion, wherein a first opening is formed in a bottom of the ball discharge portion, and a second opening is formed in the partition at a lower portion thereof; a rotatable opening/closing plate rotatably coupled to the partition, wherein the rotatable opening/closing plate is configured to rotate to open/close the second opening; and a ball discharge tube rotatably coupled to the ball discharge portion at the first opening, wherein the ball discharge tube ball-communicates with the ball discharge portion via the first opening.

The current invention is a golf ball retriever that enables an individual to pick up a golf ball without requiring the user to bend over. The golf ball retriever includes an extendable rod with a cup configured to receive a golf ball disposed at a distal end of the rod. In one embodiment, the extendable rod is in a telescopic arrangement movable between an extend position and a retracted position. In use, the rod is extended and the cup is pressed over the ball. The cup receives the ball, and the ball remains within the cup until removed by a user.

Various embodiments of a golf putter having a putter head attached to an elongated shaft with the putter head defining a retention cavity configured to engage and retain a golf ball therein are disclosed. The retention cavity is formed along the back region of the putter head and is configured to have a diameter that is slightly less than the diameter of a regulation sized golf ball such that the golf ball is retained therein when urged into the confines of the retention cavity by the putter head. The putter head further includes an alignment aid that cooperates with the retention cavity to assist in aligning the golf putter during a putting stroke.

A golf ball pickup tool is provided. The golf ball pickup tool can be extended to an appropriate length when picking up a golf ball and can be shortened when carrying. The grip 10 is sized so as to accommodate holder pieces 11a and 11b that are slidable along the slide guide 17. The holder pieces 11a and 11 b are joined and fixed to each other at one ends thereof and are urged so as to close the other ends. A golf ball is held between the other ends of the holder pieces 11a and 11b in the state of the holder pieces 11a and 11b being taken out of the grip 10.
