Coordinators often ask for “a STEM lab” when they mean three different rooms. iLab School treats them as related, but they are not the same purchase.
STEM classroom lab
A STEM room is for science and electronics periods: boards, sensors, power, and measurement that more than one grade can share. It does not have to follow the AIM ATL sheet. Start here if there is no grant and the school wants weekly making without ATL documentation.
Atal Tinkering Lab
An Atal Tinkering Lab is an AIM / NITI Aayog shaped lab. The bill of materials is the four packages (electronics, 3D, tools, safety). Buy this when the school has an ATL code, a grant, or wants that exact compliance language on the GST invoice.
Robotics lab
A robotics lab for schools is a narrower kit: chassis, motors, sensors, and projects students finish in a period (path-follow, RC, vision). It is the right first buy for a robotics club or a single period, and it can sit inside a STEM or ATL room later.
AI classroom
An AI lab is software-plus-kits for grades 6–12: coding platforms and a first vision or chatbot lab. It needs teacher plans more than a 3D printer.
A practical order for a CBSE school in NCR
If a grant exists, buy the ATL complete lab and add robotics projects from the same boards. If there is no grant and one period, buy the robotics lab. If the school wants coding and AI on the timetable, add the AI classroom on the same PO. iLabTek can mix all three on one invoice from Noida.
