A dual-purpose auxiliary training robot for tennis and badminton driven by soft cables

Abstract

The invention provides a novel flexible cable driving tennis badminton biservice auxiliary training robot. The robot comprises four flexible cable driving devices which are distributed on the four corners of a court, eight flexible cables and an end launch device, wherein each flexible cable driving device comprises a base, a stand column which is arranged on the corresponding base, a pair of flexible cable actuators and a top pulley which is mounted at the top end of the corresponding stand column, and each flexible cable actuator is connected to one flexible cable; of the two flexible cables which are driven by the same flexible cable driving device, one is directly connected with the end launch device, and the other one passes round the top pulley and then is connected with the end launch device; the position and launch angle of the end launch device are controlled by the eight flexible cables. The novel flexible cable driving tennis badminton biservice auxiliary training robot has the advantages that the design is scientific, the mobile serve space is big, the serve actions can be electrically controlled, the serve frequency is improved and the expansibility is good.

Description

technical field [0001] The invention relates to a robot, in particular to a novel flexible rope-driven tennis and badminton dual-purpose auxiliary training robot. Background technique [0002] Tennis players usually practice only by hitting the ball against a wall without being accompanied by a training staff. However, the direction and speed of the ball after rebounding are difficult to control and lack of interaction. This method is difficult to effectively standardize and improve the practicer's hitting technique. [0003] And for badminton training, its self-training method is more limited. [0004] Most of the tennis or badminton trainers on the market adopt the counter-rotating double-wheel mechanism similar to the baseball launching device to launch the tennis balls. Such tennis or badminton auxiliary training devices are usually bulky and fixed in position, and their service range can only cover a limited fan-shaped area of ​​the court in front of the device, which...

AI Technical Summary

Problems solved by technology

Such tennis or badminton auxiliary training devices are usually bulky and fixed in position, and their serving range can only cover a limited fan-shaped area of ​​the court in front of the device, which cannot meet the requirements of flexible serving on the whole court

[0005] Although some designers have also proposed training devices that use pneumatic devices to serve to reduce weight, such devices also have the disadvantage of limited coverage of the ball. In addition, how to provide a stable and quiet air source for this type of pneumatic device has also become a challenge. major barriers to adoption
