Class 4 Explorer Kit: Smart Circuits & Autonomous Systems

Original price was: ₹ 8,000.00.Current price is: ₹ 5,559.00.

Turn curiosity into autonomous creation. The Class 4 XR4STEM Kit introduces 9-year-olds to the magic of smart electronics, structural engineering, and optics—empowering them to build automatic doors, fire alarms, and 3D holograms from scratch.

The leap from simple toys to intelligent systems begins here. The Class 4 Explorer Kit is an immersive, hands-on laboratory designed to introduce students to the fundamentals of autonomous input/output logic, basic structural engineering, and optical physics.

Engineered by XROBOTICS WORKS PVT LTD, an IIT Bhubaneswar-incubated tech ecosystem, this kit is perfectly mapped to accelerate students into PM Shri Labs and advanced Composite Skill Labs. Instead of just reading about circuits, students will actively program the Arduino UNO SMD to read real-world data. They will wire a Flame Sensor to trigger a 5V buzzer for a Fire Alarm, use an IR Sensor and an SG90 Servo to build an Automatic Door, and utilize an LDR (Light Dependent Resistor) to design energy-saving Smart Street Lights.

Beyond coding, the kit dives deep into applied science. Students will explore image formation by building a Pinhole Camera and a Hologram projector, understand the states of matter by mixing Slime and Corn Starch semi-solids, and test chemical electricity with a Lemon Battery. With 16 distinct projects, this kit transforms passive learning into dynamic, autonomous engineering.
