A Unique 3D-Printed Shuttlecock Launcher With Three-Layer Sorting, Adjustable Positioning Barrier, and Dynamic Motor Holder

Abstract

Currently, 3D printing technology enables the production of lightweight, durable, and precise parts constructed from readily available materials in the general market. In this study, the prototype of a shuttlecock launcher was designed and created using this technology. 57% of the total weight is attributed to components constructed from polylactic acid (PLA+). Based on the analysis, the prototype was able to operate on a stable structure with three functions: sorting, passing, and launching the shuttlecocks. The performance focused on measuring the delay in response to commands and previous shots, as well as the launch velocity and distance of the shuttlecock traveling parallel to the ground of this prototype. The evaluation demonstrated that the shuttlecock launcher effectively propelled shuttlecocks forward, achieving a maximum initial velocity of 11 m/s and covering a distance of 3.365 m. The launching process, initiated upon receiving a command, required 1.0–1.1 s, with an interval of 1.4–1.5 s between consecutive launches. Additionally, the system could accommodate shuttlecocks of varying usage levels, with an observed error margin of approximately 4%. This model is registered under Thailand petty patent No. 21044 and patent No. 2101004228(A). With its demonstrated shuttlecock launching performance and lightweight design, this prototype can be practically utilized on badminton courts and in specific court areas for training purposes, offering easy portability and convenient setup
