Development of the crossbow-type launcher for a small reconnaissance robot based on the axiomatic theorem

Recently, the development of small reconnaissance robots has been actively studied for the purpose of remote monitoring. However, difficulties related to the robot gaining access to a distant target area have been encountered in this research area. In this paper, a cross-bow-type launcher, which uses elastic energy to launch, was developed to launch a small robot to a designated target location. The design parameters were determined based on commercial users' comments and axiomatic design methodology to optimize the launcher system. This crossbow system was developed to satisfy functional requirements, such as protecting the robot during the launching process and achieving long-range shooting over 100 m, an accurate shooting range, high portability and ease of operation. In addition, field experiments were conducted to validate the performance of the developed launcher system.
