Technical Field
[0001] This invention relates to the field of robotics, specifically to an intelligent projection robot. Background Technology
[0002] "Pitch-pot" is an ancient Chinese traditional etiquette and game. During the Spring and Autumn and Warring States periods, one of the rituals for feudal lords when entertaining guests was to invite them to shoot arrows, called "archery ceremony." Later, to allow guests who were not good at archery to participate in the game, arrows were thrown into a wine pot instead, to entertain the guests and to teach etiquette. Over time, pitch-pot became a way to entertain guests at banquets and an elegant competition. However, current pitch-pot robots require manual arrow release, resulting in low accuracy.
[0003] This invention is applicable to various types of robot competitions, and the finished product has strong application value. It is easy to assemble, uses pneumatic and electric power as the main power source, and the structure is mainly made of steel such as aluminum alloy, so the material cost is low. It can also be used in life and entertainment, and is open to the general public. Summary of the Invention

[0014] In one embodiment of the present invention, an arrow support plate is provided on the top surface of the main rod near the end of the damper.

The bottom surface of the single chain of the chain moving bar with the grippers can slide on the surface of the third slide rail by a sliding block.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. The four brushless motors rotate, driving the four omnidirectional wheels to rotate, thereby enabling the projection robot to move. The gas cylinder is installed through the gas cylinder fixing plate, thereby supplying gas to the gas-using device in the projection robot and enabling the projection robot to work normally.
[0020] 2. When retrieving the arrow, the fourth cylinder retracts, causing the rocker arm to move outward around the hinge with the connecting rod. During the movement, the rocker arm meshes with the fixed second spur gear and the bearing-mounted third spur gear, causing the third spur gear to rotate around the second spur gear. This, in turn, drives the first synchronous wheel to rotate forward. The crossbar is hinged to the rocker arm, and the first synchronous wheel is driven by a belt to the fixedly mounted second synchronous wheel, causing the crossbar to move outward. The extension of the third cylinder causes the chain moving bar to extend, and the gripper grasps the arrow. When releasing the arrow, the third cylinder retracts, causing the chain moving bar to fold and the grippers to move closer together. The fourth cylinder extends, moving the rocker arm closer to the projection mechanism. This, along with the second and third spur gears, the first and second synchronous pulleys, moves the crossbar closer to the arrow placement mechanism, and the grippers place the retrieved arrow onto the mechanism. When loading the arrow, the fifth brushless motor rotates, driving the gear set. The centers of the spur gears on both sides are hinged to the surface of the first arrow lifting plate via a first connecting rod. The centers of the spur gears on both sides are also fixedly connected to a second connecting rod via a drive shaft passing through the first arrow lifting plate. The other end of the second connecting rod is hinged to the surface of the second arrow lifting plate, thus enabling the movement of the first and second arrow lifting plates, placing the arrow on the power storage mechanism, and ensuring accurate projection. In preparation, the second cylinder retracts, causing the puller to move diagonally upwards. When the hook in the puller contacts the arrow-pushing slider, the servo motor inside the puller controls the hook to engage with the arrow-pushing slider. After engagement, the second cylinder extends, causing the puller to pull the arrow-pushing slider to its extension limit. After the arrow-retrieving mechanism releases the arrow, the fifth brushless motor loads the arrow. The arrow body is supported by the arrow holder and the arrow-pushing slider. The fourth brushless motor rotates, driving the second lead screw to rotate, causing the rubber band fixing block to move on the second lead screw. A rubber band is provided between the rubber band fixing block and the arrow-pushing slider, and the rubber band passes around the rubber band pulley. Therefore, by controlling the number of rotations of the fourth brushless motor, the distance between the rubber band fixing block and the rubber band pulley is controlled, thereby controlling the pulling force of the rubber band on the arrow-pushing slider, thus achieving control of the arrow projection distance. During projection, the servo control hook in the puller releases the arrow-pushing slider. The arrow-pushing slider slides rapidly on the first slide rail under the pull of the rubber band, and pushes the arrow support plate through the first cylinder, making the arrow support plate horizontal at the moment of arrow projection, thus realizing the projection of the arrow.
[0021] 3. The horizontal angle adjustment of the projection mechanism is achieved by the main control mechanism sending a signal to the encoder, which in turn sends an electrical signal to the third brushless motor. The third brushless motor drives the first spur gear to rotate, and the first spur gear meshes with the internal gear ring. The chassis ring bearing is mounted on the top surface of the internal gear ring. Therefore, the horizontal adjustment of the projection mechanism can be achieved when the third brushless motor rotates forward and backward. For vertical angle adjustment, the main control mechanism sends a signal to the encoder, which in turn sends an electrical signal to the second brushless motor. The second brushless motor rotates, causing the lead screw nut to rotate. The inside of the lead screw nut is threadedly connected to the surface of the first lead screw. The first lead screw can pass through the second brushless motor. The top of the first lead screw is hinged to the bottom surface of the damper near the top, and the top of the first vertical frame is also hinged to the bottom surface of the damper near the bottom. Therefore, during the rotation of the four-bar nut, the first lead screw pulls the damper in the projection mechanism downward or upward, thereby driving the main rod to achieve vertical angle adjustment.
[0022] 4. This invention enables the movement of the projection robot through a base mechanism, the retrieval and release of arrows through an arrow-collecting mechanism, and the projection mechanism for projecting the arrows. The projection mechanism includes an angle adjustment mechanism, a power storage mechanism, and an arrow placement mechanism. The angle adjustment mechanism includes horizontal and vertical angle adjustment, thus enabling precise arrow projection. This invention is suitable for various types of robot competitions and has strong application value. It is simple to assemble, uses pneumatic and electric power as the main power sources, and is mainly made of aluminum alloy and other steel materials, resulting in low material costs. It can also be used in daily life and entertainment, making it accessible to the general public.

Through the second spur gear 4010, the third spur gear 4011, the first synchronous wheel 4012, and the second synchronous wheel 4013, the crossbar 4003 moves towards the arrow body placement mechanism, and the grippers 4009 place the retrieved arrow onto the arrow body placement mechanism.
[0040] For details, please refer to the appendix. Figure 4-6As shown, when the arrow is loaded, the fifth brushless motor 3033 rotates, driving the gear set 3034 to rotate.

[0041] The projection mechanism 300 includes an angle adjustment mechanism, a power storage mechanism, and an arrow placement mechanism. The angle adjustment mechanism includes horizontal and vertical angle adjustment. The arrow placement mechanism is located on one side of the power storage mechanism. The power storage mechanism includes a damper 3012. The angle adjustment mechanism includes an internal gear ring 3001, a chassis ring 3002, a first vertical frame 3003, a first horizontal frame 3004, a second brushless motor 3005, a third brushless motor 3010, an encoder 3009, and a first lead screw 3007. One end of the first lead screw 3007 is hinged to the bottom surface of the damper 3012 near the top end. The top end of the first vertical frame 3003 is hinged to the bottom surface of the damper 3012 near the bottom end. The second brushless motor 3005 is used for vertical angle adjustment, the third brushless motor 3010 is used for horizontal angle adjustment, and the encoder 3009 is used to transmit electrical signals to the second brushless motor 3005 and the third brushless motor 3010.
[0042] There are two sets of the first vertical frame 3003 and the first horizontal frame 3004. The internal gear ring 3001 is fixedly installed on the top surface of the base frame 2001. The chassis ring 3002 is mounted on the top surface of the internal gear ring 3001. Both sets of the first vertical frame 3003 are set on the top surface of the chassis ring 3002 by tripods. The encoder 3009 and the third brushless motor 3010 are both set on the tripod at the bottom of the first vertical frame 3003. The output end of the third brushless motor 3010 is provided with a first spur gear 3011, and the first spur gear 3011 meshes with the internal gear.
[0043] For details, please refer to the appendix. Figure 4-5 As shown, the horizontal angle adjustment of the projection mechanism 300 is achieved by the main control mechanism sending a signal to the encoder 3009, which in turn sends an electrical signal to the third brushless motor 3010. The third brushless motor 3010 drives the first spur gear 3011 to rotate. The first spur gear 3011 meshes with the internal gear ring 3001, and the chassis ring 3002 bearing is mounted on the top surface of the internal gear ring 3001. Therefore, the horizontal adjustment of the projection mechanism 300 can be achieved when the third brushless motor 3010 rotates in both directions.
[0044] One end of each of the two sets of first horizontal frames 3004 is horizontally mounted near the top of the two sets of first vertical frames 3003. The bearings on both sides of the second brushless motor 3005 are mounted between the ends of the two sets of first horizontal frames 3004 away from the first vertical frames 3003. The output end of the second brushless motor 3005 is connected to a lead screw nut 3006, and the second brushless motor 3005 is hollow. The inside of the lead screw nut 3006 is threadedly connected to the surface of the first lead screw 3007, and the first lead screw 3007 can pass through the second brushless motor 3005.
[0045] For details, please refer to the appendix. Figure 4-5 As shown, the projection mechanism 300 adjusts its angle in the vertical direction. The main control mechanism sends a signal to the encoder 3009, which in turn sends an electrical signal to the second brushless motor 3005. The second brushless motor 3005 rotates, causing the lead screw nut 3006 to rotate. The inside of the lead screw nut 3006 is threadedly connected to the surface of the first lead screw 3007. The first lead screw 3007 can pass through the second brushless motor 3005. The top of the first lead screw 3007 is hinged to the bottom surface of the damper 3012 near the top, and the top of the first vertical frame 3003 is hinged to the bottom surface of the damper 3012 near the bottom. Therefore, during the rotation of the four-bar nut 3006, the first lead screw 3007 pulls the damper 3012 in the projection mechanism 300 to move downwards or upwards, thereby driving the main rod 3013 to achieve angle adjustment in the vertical direction.
[0046] The power storage mechanism includes a damper 3012, and the angle adjustment mechanism includes an internal gear ring 3001, a chassis ring 3002, a first vertical frame 3003, a first horizontal frame 3004, a second brushless motor 3005, a third brushless motor 3010, an encoder 3009, and a first lead screw 3007. One end of the first lead screw 3007 is hinged to the bottom surface of the damper 3012 near the top end, and the top end of the first vertical frame 3003 is hinged to the bottom surface of the damper 3012 near the bottom end. The second brushless motor 3005 is used for vertical adjustment. The vertical angle adjustment is provided, while the horizontal angle adjustment is provided by the third brushless motor 3010. The encoder 3009 transmits electrical signals to the second brushless motor 3005 and the third brushless motor 3010. The power storage mechanism also includes a main rod 3013, with a damper 3012 sleeved on the surface of the main rod 3013 near one end. The top and bottom surfaces of the main rod 3013 are respectively provided with a first slide rail 3023 and a second slide rail 3032. The top surface of the main rod 3013 has clearance grooves on both sides of the first slide rail 3023. Inside the rod 3013, near the damper 3012, is a second cylinder 3016 aligned with the central axis of the main rod 3013. The pushing end of the second cylinder 3016 is fitted with a puller 3021 via a connecting block passing through a clearance groove. The pulling end of the puller 3021 is positioned opposite to the working end of the damper 3012. A pusher slider 3022 is mounted on the first slide rail 3023, and a rubber band fixing block 3019 is mounted on the second slide rail 3032. The interiors of the main rod 3013 and the damper 3012 are located within the second cylinder 3016. A rubber band pulley 3020 is also provided on one side of the cylinder liner of 016. A fourth brushless motor 3018 is also provided at the bottom end of the main rod 3013 away from the damper 3012. The output end of the fourth brushless motor 3018 is connected to a second lead screw 3017. The other end of the second lead screw 3017 passes through the rubber band fixing block 3019 and is mounted on the opposite end surface of the damper 3012 and the fourth brushless motor 3018. A rubber band is provided between the rubber band fixing block 3019 and the push arrow slider 3022, and the rubber band passes around the rubber band pulley 3020.
[0047] An arrow support plate 3014 is provided on the top surface of the main rod 3013 near the damper 3012. The top of the arrow support plate 3014 is used to support the arrow. The arrow support plate 3014 is hinged to the main rod 3013 near the center. The bottom of the arrow support plate 3014 is hinged to the pushing end of the first cylinder 3015. The cylinder sleeve end of the first cylinder 3015 is located inside the damper 3012. The arrow pusher slider 3022 can engage with the hook in the puller 3021. The puller 3021 includes a hook and a servo motor. The servo motor is used to control the engagement and disengagement of the hook and the arrow pusher slider 3022.
[0048] For details, please refer to the appendix. Figure 6As shown, during the projection preparation, the second cylinder 3016 retracts, driving the puller 3021 to move obliquely upwards. When the hook in the puller 3021 contacts the arrow-pushing slider 3022, the servo motor inside the puller 3021 controls the hook to engage with the arrow-pushing slider 3022. After engagement, the second cylinder 3016 extends, causing the puller 3021 to pull the arrow-pushing slider 3022 to its extension limit. After the arrow-retrieving mechanism 400 completes the arrow release, the fifth brushless motor 3033 completes the arrow loading. The arrow body is supported by the arrow support plate 3014 and the arrow-pushing slider 3022. The fourth brushless motor 3018 rotates, driving the second lead screw 3017 to rotate, thus realizing the rotation of the rubber band fixing block 3019 on the second lead screw. The arrow moves on 3017, and a rubber band is provided between the rubber band fixing block 3019 and the arrow pusher slider 3022. The rubber band passes around the rubber band pulley 3020. Therefore, the distance between the rubber band fixing block 3019 and the rubber band pulley 3020 is controlled by controlling the number of rotations of the fourth brushless motor 3018, thereby controlling the pulling force of the rubber band on the arrow pusher slider 3022. Thus, the arrow projection distance is controlled. When projecting, the servo control hook in the puller 3021 releases the arrow pusher slider 3022. The arrow pusher slider 3022 slides rapidly on the first slide rail 3023 under the pull of the rubber band, and pushes the arrow support plate 3014 through the first cylinder 3015, so that the arrow support plate 3014 is flattened instantly when the arrow is projected, thus realizing the arrow projection.
