Multiple robots may be grouped together to make a counter-blow to form a robot race.

A pan head, a projectile launching system and a robot according to some embodiments of the present invention are described below with reference to fig. 1 to 21.

As shown in fig. 1 and 2, an embodiment of the first aspect of the present invention provides a cloud deck, which is configured to be connected to a projectile launching device 500, where the projectile launching device 500 is configured to launch a projectile 700, where the cloud deck includes: a first motor 100 and a projectile tube 200. Specifically, one end of the shot pipe 200 is used to connect the shot-firing device 500, and the other end is connected to the first motor 100. It will be appreciated that the projectile tube 200 may be directly connected to the first motor 100 or indirectly connected through an intervening component, such that the first motor 100 can drive the projectile tube 200 to rotate. The first motor 100 comprises a motor shaft 110, a through hole 111 penetrating in the axial direction is formed in the motor shaft 110, and the aperture of the through hole 111 is larger than the outer diameter of the projectile 700, so that the projectile 700 can sequentially pass through the through hole 111 and the projectile pipeline 200 and be conveyed to the projectile launching device 500.

Wherein, the first motor driving the pellet pipeline 200 to rotate may be used for realizing the rotation of the pellets 700 in the pellet pipeline 200, for example, when the pellet pipeline 200 is a spiral pipeline, the rotation of the pellets 700 may be realized through the rotation of the pellet pipeline 200. Alternatively, the projectile tube 200 may be driven to drive the projectile launching device 500 to rotate or directly drive the projectile launching device 500, so that the projectile launching device 500 has at least one rotational degree of freedom, and a plurality of angles of projectile launching are realized, and thus, the first motor 100 is used to drive the projectile tube 200 and the projectile launching device 500, so that the rotational synchronism of the projectile tube 200 and the projectile launching device 500 is more reliable, and the communication effect between the projectile tube 200 and the projectile launching device 500 is more stable and reliable.

Meanwhile, the shot 700 in the structure can be directly transmitted along the motor shaft 110 of the first motor 100, so that the driving work of the first motor 100 cannot be hindered, the integrated connection of driving and conducting between the shot pipeline 200 and the first motor 100 is realized, and the shot pipeline 200 does not need to be driven to rotate through a huge and complex transmission mechanism, so that the cradle head structure is simpler, the size is smaller, the problems of control response speed and precision caused by the transmission mechanism are solved through the direct driving of the first motor, the compatible effect between the cradle head and the shot launching device 500 is better, and the overall precision of the cradle head is correspondingly improved. In this embodiment, as shown in fig. 3, the cradle head further includes a connecting assembly 300, and the connecting assembly 300 is disposed on the first motor 100 and is used for supporting the projectile launching device 500; the first motor 100 is also used to drive the connection assembly 300 to rotate. Like this, utilize first motor 100 simultaneous drive coupling assembling 300, shot emitter 500 and shot pipeline 200 to rotate, the adaptation effect between shot emitter 500 and the coupling assembling 300 is better, and also more do benefit to the rotation synchronism who guarantees between shot emitter 500 and the shot pipeline 200, it drags a tub problem to avoid appearing between shot emitter 500 and the shot pipeline 200 because of rotating asynchronous appearance, thereby the connection reliability of shot pipeline 200 and shot emitter 500 has been promoted.
