The BOSON Inventor Series Royal Guard Kit is a coding-free STEAM project for students in Grades 1–3. Using plug-and-play BOSON modules, learners build a royal guard that begins patrolling when it detects someone approaching — teaching the fundamentals of motion sensors and servo control through hands-on assembly.

The kit includes all electronic modules, craft materials, and a paper model sheet. No coding or soldering is required. The workshop takes approximately 45 minutes to complete.
