Development of an Archery Robot for the Selection of Arrows

Abstract

The appropriate selection of arrows in the sport of archery is important to the achievement of high-quality results. In this regard, a shooting machine that is compatible with the wide variety of available bows and arrows is necessary. However, bow strength and arrow length vary among different athletes. It is also important to develop a shooting machine that reproduces the movement of the right fingers that releases an arrow, and the forward jump of a bow after shooting an arrow. In this study, a shooting machine was developed that considered these factors. Its efficacy was examined in terms of its ability to determine the characteristics of each arrow, and to distinguish between normal and flawed arrows. Based on the experimental results, we identified the factors that affected the shooting accuracy of arrows. In addition, the developed shooting machine was able to distinguish between normal and flawed arrows.

“…While no research has been done on the specific shooting robot created by Hyundai Motor Group, a research experiment was run in Japan, where experimenters designed and developed their own shooting machine that could shoot at a target 70 meters away (Ohara et. al., 2020).…”

“…al., 2020). The research designed the shooting robot to be highly advanced and closely replicate a human's shot cycle, incorporating details such as allowing the bow to naturally jump forward as a reaction of the shot and creating a realistic human hand model to draw and pull the bow (Ohara et. al., 2020).…”

“…al., 2020). The machine was designed to be over 100kg to limit its movement after a shot, as the recoil can cause lighter robots to potentially shift, reducing the consistency of the robot (Ohara et. al., 2020).…”

“…al., 2020). The experimenters used the robot to shoot six arrows to a target 70 meters away, but two arrows were intentionally abnormal and slightly altered (Ohara et. al., 2020).…”

“…al., 2020). They found that the machine could successfully identify the abnormal arrows from the normal arrows, as two arrows would always hit the target in a vastly different area than the four normal arrows (Ohara et. al., 2020).…”
