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.\n\nThe 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.\n\nKey Features\n\n\nPlug-and-Play – No coding or soldering required\n\nComplete Kit – Electronic modules, craft materials, and lesson plan included\n\nInteractive Project – Motion sensor triggers servo-powered patrol movement\n\nGrades 1–3 – Designed for approximately 45-minute workshops\n\n\nLearning Objectives\n\nUnderstanding motion sensors and how they detect movement\nLearning how servos convert electrical signals to mechanical motion\nBuilding and wiring a simple interactive circuit\nHands-on craft and assembly skills\n\n\nSpecifications\n\n\nOperating Voltage – 4.5–5.5 V (3× AAA batteries)\n\nDimensions – 355 × 240 × 40 mm (packaged)\n\nWeight – 197 g\n\n\nPackage Contents\n\n1× BOSON Mainboard-1IO\n1× BOSON Motion Sensor\n1× BOSON Servo Controller Module\n1× BOSON 9 g Metal Gear Micro Servo\n1× BOSON 3× AAA Battery Holder\n2× 3-pin cables (100 mm)\n2× Paper model sheets\n1× Quick start card\n","vendor":"DFRobot","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":568,"title":"Default Title","sku":"DF-TOY0083-1","mpn":"TOY0083-1","price":56.0,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
