Clear Answers
Frequently Asked Questions (Robotics & STEM)
Safety, shipping, and online vs offline hardware mentoring.
How safe are these electronics kits for children at home?
100% safe! Everything runs on low-voltage 5V USB or AA batteries using push-in jumper wires — no soldering iron or high-voltage AC required.
How do mentors guide hardware wiring during online 1-on-1 classes?
Students first verify circuits in Tinkercad 3D simulator, then mentors inspect physical breadboard pins live over camera step-by-step.
When is the STEM hardware kit delivered?
Within 5–7 business days of track enrollment across all Indian cities (plus UAE/Singapore shipping supported).
Can students reuse kits for school science exhibitions and WRO?
Yes! The Arduino and sensor kits are permanent ownership — kids proudly enter them in school exhibitions and NITI Aayog ATL marathons.
