Description

TECHNICAL FIELD

[0001] The present application belongs to the field of robots, and in particular to a directional rotation method. BACKGROUND

[0002] As a small type of separator, darts are increasingly popular as a form of entertainment for people. With the development of automated equipment, users can use small aircraft launchers to replace manual dart launching for entertainment. At the same time, small aircraft launchers need to launch darts to hit an armored plate the size of a half A4 paper 16 meters away and 20 meters away to achieve the ability to attack buildings at a long distance and high damage. The launch structure of the small aircraft launcher is similar to that of the ball launcher, which needs to throw objects such as shuttlecocks, tennis balls, and table tennis balls.

[0003] The existing Chinese patent application No. 202122973792.9, published on April 8, 2022, relates to a dart continuous launcher in the field of robots. It includes a direction adjustment module, a launching module, a bottom plate, and a dart. The launching module is located above the direction adjustment module, which is fixed on the bottom plate. The dart is installed in the launching module. The direction adjustment module includes an electric turntable and an electric telescopic rod, which control the yaw angle and pitch angle of the launching module, respectively. The launching module is composed of a bullet feeder, a dart holder, an accelerator, and a direction stabilizer. The bullet feeder can push the dart from the standby position to the launcher position and engage with the friction wheel of the accelerator. The dart holder is used to store the dart ready for launching and can complete reloading under the action of gravity. The accelerator uses a pair of friction wheels to accelerate the dart. The direction stabilizer is used to stabilize the launching direction. It has a small volume and is easy to carry. It can store multiple darts and achieve automatic loading and launching. It can be remotely controlled and automatically operated. It has high running speed and efficiency and can be suitable for teaching experiments, robot training, and competitions. However, the utility model directly adjusts the launcher through an electric turntable, which has a large load and slow rotation speed, and the rotation structure is unreliable. SUMMARY
