Abstract: An unmanned ground vehicle (UGV) includes one or more motors configured to drive one or more wheels of the UGV, a memory storing instructions, and a processor coupled to the one or more motors and the memory. The processor is configured to execute the instructions to cause the UGV to determine location information of a movable target; calculate a direction and a speed for the unmanned ground vehicle based on the determined location information; and drive the one or more motors to move the unmanned ground vehicle in the calculated direction at the calculated speed to follow the movable target when the movable target moves.

Abstract: A football game machine includes a goal device divided into multiple strike areas that respectively indicates different score marks. Each strike area has multiple pressure sensor mounted therein. Two casing mounted to two opposite sides of the goal device. Each casing has an inner side having a series of photoelectric cells mounted thereon. The football game machine can calculate the speed of the flying ball by using the time difference of the photoelectric cells and the pressure sensor. A display device is mounted on the goal device for displaying the total scores and the speed of the flying ball. A ball recycle device is mounted in one of the two casings. A football is connected to the ball recycle device via a rope. The ball recycle device can recycle the ball when the game is finished and release the rope before playing the ball.

Abstract: A cotton candy machine includes a housing and a stick grabbing device mounted in the housing. A stick rotating device is mounted in the housing and aside corresponds to the stick grabbing device. A feeding device is mounted in the housing and a sugar floss maker is horizontally mounted in the housing under the stick rotating device. The stick grabbing device provides stick one by one and conveys the stick to the stick rotating device. The stick rotating temporarily holds the stick, rotates the stick and makes the stick longitudinally insert into the sugar floss maker for coiling the sugar floss from the sugar floss maker after the feeding device providing sugar material into the sugar floss maker.

Abstract: A shooting game machine includes a shell, a gun, and at least one goal-and-carrier assembly. The goal-and-carrier assembly includes a base located in and attached to the shell, a carrier movably supported on the base, and at least one goal unit. The goal unit includes a frame supported on the carrier, a goal pivotally connected to the frame between a raised position and a shut-down position, a crank rotationally connected to the frame, a lever connecting the goal to the crank, a turntable rotationally connected to the frame, magnets attached to the turntable. The magnets attract the crank so that the goal is retained in the raised position until it is effectively hit by a bullet. A motor is operatively connected to the turntable. The motor rotates the turntable when the goal reaches the shut-down position and stops when the goal reaches the raised position.

Abstract: A doll-based game machine includes a frame, a doll-hanging unit, a displacement unit, a string-cutting unit and an operation unit. The frame includes an opening defined therein. The doll-hanging unit is located in the frame and used to hang dolls. The displacement unit includes an X-axis displacement unit located in the frame, a Y-axis displacement unit connected to the X-axis displacement unit, and a cutter-carrying unit connected to the Y-axis displacement unit. The string-cutting unit is carried by the cutter-carrying unit. The operation unit is located on the frame and operable to cause the X-axis displacement unit to move the Y-axis displacement unit along an X-axis, to cause the Y-axis displacement unit to move the cutter-carrying unit along a Y-axis, and to turn the string-cutting unit into a cutting mode from an idle mode.

Abstract: Disclosed is an apparatus for supporting and decorating a window. The apparatus includes a frame, a lamp and a lens assembly. The frame includes a middle slab formed between two lateral slabs. Each of the lateral slabs includes a window-receiving groove, a V-shaped groove and a lens-receiving groove. The depth of the window-receiving groove of each of the lateral slabs is at an angle from that of the window-receiving groove of the other lateral slab. The middle slab is in parallel to a plane in which valleys of the V-shaped grooves of the lateral slabs lie. The lamp includes illuminators supported on a board. The board includes two edges inserted in the V-shaped grooves. The lens assembly includes lenses each including at least two tongues each extending from a side and including a tip movably inserted in the lens-receiving groove of a related one of the lateral slabs.
