A visual-based badminton picking trolley

Abstract

This invention discloses a vision-based badminton shuttlecock retrieval cart, comprising a frame, a front collection assembly, a lifting platform, an electric push rod, drive wheels, a main control and power supply box, a vertical support, a vision sensor assembly, a rear guide ramp, and a shuttlecock storage cylinder. The main control and power supply box is located in the middle of the frame. The vision sensor assembly is mounted on the vertical support for identifying badminton shuttlecocks. The front collection assembly is located at the front of the frame, sweeping badminton shuttlecocks from the ground into the lifting platform at the bottom. The lifting platform is located behind the front collection assembly, and its bearing surface is set as a rearward inclined ramp. The electric push rod is connected to the lifting platform, driving it to move up and down along the vertical support. When the lifting platform rises to its highest position, the badminton shuttlecocks, under the influence of gravity, naturally slide down the inclined surface to the rear guide ramp, and finally fall into the shuttlecock storage cylinder. This invention achieves smooth transport of badminton shuttlecocks from the ground to the storage cylinder through the cooperation of the push rod and the inclined platform, resulting in a high degree of automation.

Description

Technical Field

[0001] This invention relates to the field of intelligent service robots, and more particularly to a vision-based badminton shuttlecock retrieval vehicle. Background Technology

[0002] During daily badminton training or matches, a large number of shuttlecocks are scattered on the court. Traditional cleanup methods rely heavily on manual bending and picking them up, which is not only labor-intensive and physically demanding but also inefficient, wasting valuable court time. With the popularization of machine vision and automation technologies, some shuttlecock-collecting aids have appeared on the market, but most are semi-manual trolley structures or lack precise autonomous shuttlecock-finding capabilities. Therefore, there is an urgent need for an automated device that can automatically identify, accurately locate, and efficiently collect shuttlecocks. Summary of the Invention

[0003] The purpose of this invention is to provide a vision-based badminton shuttlecock retrieval cart, which aims to solve the problems of low efficiency, high physical exertion, and insufficient automation of traditional manual shuttlecock retrieval.

[0004] To achieve the above objectives, the present invention provides a vision-based badminton shuttlecock retrieval cart, comprising a frame, a front collection assembly, a lifting platform, an electric push rod, drive wheels, a main control and power supply box, a vertical support, a vision sensor assembly, a rear guide ramp, and a shuttlecock storage cylinder; the main control and power supply box is located in the middle of the frame; the drive wheels are mounted at the four corners of the bottom of the frame; the vertical support is fixed to the front-middle part of the frame; the vision sensor assembly is mounted on the vertical support for target identification; the front collection... The component is located at the front bottom of the frame and is used to sweep badminton shuttlecocks from the ground backward; the lifting platform is located directly behind the front collecting component and is used to receive the badminton shuttlecocks, with its bearing surface sloping downward and backward; the electric push rod is symmetrically installed on both sides of the vertical support, and its telescopic end is connected to the lifting platform to drive the lifting platform to move vertically; the rear guide plate is fixed to the rear of the vertical support; the shuttlecock storage cylinder is placed vertically at the rear of the frame to receive the badminton shuttlecocks that slide down from the guide plate.

[0005] The drive wheels are Mecanum wheels, with a total of four, which enable translation, rotation, and omnidirectional movement on the badminton court to align with the shuttlecock via the fastest path.

[0006] The visual sensor assembly includes two sets of sensors respectively installed at the top and upper middle part of the vertical support, forming a visual coverage angle with varying heights, thereby improving the accuracy of identifying badminton shuttlecocks at close and long distances.

[0007] The front collecting assembly includes a front bucket that is inclined and close to the ground and a collecting roller that spans above the bucket. The collecting roller is driven to rotate by a roller drive motor, and the flexible lever on its surface pushes the shuttlecock along the inclined surface of the bucket into the lifting platform behind it.

[0008] The lifting platform is equipped with side baffles on both sides to prevent it from falling. When the electric push rod raises the lifting platform to its highest position, the lowest end of the inclined bearing surface of the lifting platform is flush with the highest end of the rear guide plate, allowing the shuttlecock to pass smoothly.

[0009] The lowest end of the rear guide plate is directly opposite the opening of the ball storage cylinder; the ball storage cylinder is fixed to the base at the rear end of the vehicle frame.

[0010] This invention discloses a vision-based badminton shuttlecock retrieval cart. Utilizing a visual sensor for precise positioning, its omnidirectional drive wheels flexibly approach the target. After the shuttlecocks are swept into the lifting platform by the front collection component, an electric push rod lifts the inclined platform to a higher position, allowing the shuttlecocks to slide naturally down the slope into the storage tank under gravity. By using a ramp for guidance, the complex tracked or piped conveying mechanism is eliminated, reducing the shuttlecock jamming rate and significantly improving the automation level of court cleaning.

[0016] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0017] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] Please see Figures 1 to 2 This invention provides a vision-based badminton shuttlecock retrieval cart. The entire structure is based on the frame 4, with four Mecanum wheels 3 installed at the bottom as drive wheels. Combined with the main control and power supply box 5 in the middle, the cart has the ability to move flexibly in all directions and turn on the spot, and can quickly aim at scattered badminton shuttlecocks.

[0019] A vertical bracket 6 is fixed at the front of the frame 4, on which visual sensor components 7 are mounted at varying heights. During operation, the long-focus sensor at the top is responsible for wide-area searching, while the short-focus sensor in the middle is responsible for precise close-range aiming. Once the main controller and power supply box 5 lock onto the target, the vehicle is driven forward.

[0020] At the very front of the trolley is a front collecting assembly consisting of a front bucket 2 and a collecting roller 1. The roller drive motor 10 drives the collecting roller 1 to reverse at high speed. When the trolley approaches the shuttlecock, the front bucket 2 inserts under the shuttlecock, and the flexible lever on the collecting roller 1 quickly pushes the shuttlecock backward along the inclined surface of the bucket.

[0021] At the rear receiving position of the bucket, there is a vertically movable lifting platform 11. The bearing surface of the lifting platform 11 is designed as a slope sloping backward (i.e. towards the collection bucket), and it is equipped with curved side plates on both sides to prevent badminton shuttlecocks from rolling off. In the initial state, the lifting platform 11 is at its lowest position, just catching the badminton shuttlecocks swept in by the collecting roller 1.

[0022] Two electric push rods 12 are installed in parallel on both sides of the vertical support 6. The telescopic rods of the electric push rods 12 are fixedly connected to the lifting platform 11. When the sensor detects that a badminton shuttlecock has entered the lifting platform 11, the main controller and power supply box 5 immediately control the two electric push rods 12 to extend synchronously, so as to smoothly lift the lifting platform 11 carrying the badminton shuttlecock in the vertical direction.

[0023] At the upper rear of the vertical support 6, a downward-sloping rear guide plate 8 is fixed. When the lifting platform 11 is pushed to the set height by the electric push rod 12, the tail end of its inclined bearing surface is precisely connected with the front end of the rear guide plate 8. Because the lifting platform 11 itself has a backward slope, the shuttlecock will automatically slide out along the slope of the lifting platform 11 under the action of gravity without any other external force, and transition to the rear guide plate 8.

[0024] Finally, the shuttlecock continues to slide down the rear guide ramp 8 and falls accurately into the shuttlecock storage cylinder 9 located at the rear of the frame 4. Subsequently, the electric push rod 12 retracts, and the lifting platform 11 quickly returns to its bottom position, ready to receive the next shuttlecock.

[0025] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
